What is the longest you waited in between auto oil changes?

That was not my experience. Got my first car in 1974 and the owners manual said the oil filter only needed to be changed every other oil change. So oil at 3 months, 3,000 miles, oil and filter every 6 months or 6,000 miles I did ask my mechanic about it and he says that kind of went away just because of how inexpensive an oil filter is. May as well change it.
I found an old student coupon book from my College years (1975-79). Firestone had a coupon in there for an oil and filter change for $2.99! Of course that was a way to lure in people and try and get people to have more work done. Not an issue for me as my car was new. A Fraternity brother of mine had a 12 year old Rambler station wagon with well over 100,000 miles on it. He picked it up and they handed him an estimate for about $1,000 in repairs as I recall. He laughed and pointed out he only paid $200 for the car, so no way he was spending $1,000 on it. He also pointed out that all the safety items, tires, brakes, lights, worked perfectly. Most of the repairs were for the engine, and transmission weeping fluid.
My wife got caught in that too with Firestone. When we first started dating, her 1970 Ford had over 100,000 miles on it and she took it to Firestone for an oil change and they told her she needed a new carburetor, at a cost of $150 with labor. She asked me if it was normal to need another carburetor at every oil change as they had replaced the carb 3 months before. I looked at the paperwork and it said the warranty was 6 months of 6,000 miles. I went with her to pick it up, and asked the guy what the warranty was on the carburetor and he confirmed 6 months, 6,000 miles. She handed him the last bill, and I said, "so this second carb replacement would be covered under warranty?". She looked at the last bill, and said it was. That turned a $160 bill into a $10 bill for just an oil change.

r.e. bold -- Back during my Engineering College education in 1969 my Chemical Engineering Professor who was retired from one of the MAJOR petroleum industry companies informed us Gear Head individuals that oil is forever but oil filters should be changed every 3,000 miles. His advice was for every day family vehicles NOT the HiPo toys.

Just did an oil/filter on rarely driven 2008 Taurus that replaced oil from 2022.
 
The computer in all modern cars does a calculation to determine what your remaining oil life is. I believe it uses various factors besides mileage/time
My car has the same. It takes into consideration 'how' the car is driven. Long drives, allowing proper heating of the engine, short drives, tough on engines, stop and go, freeway type driving, along with weather, hot, cold, etc. The manual states at least every 7,500 or one year, whichever is first. The onboard computer usually tells me to change about every 5-6 months, around 4,000 miles. Since retired, my driving is significantly different than before. Shorter drives, fewer miles.
 
I have a home gas-powered backup generator to use when the power happens to go out. It is a state law that you can power your home from the grid OR a backup generator but not BOTH at the same time. There is a master switch in my main electrical panel where you chose which way to get your power. Clearly back feeding power from a generator can injure/kill someone from the electrical company who happens to be working on the powerlines.

Yet the owners manuals said every other oil change for the filter. As for oil, my FIL's neighbor worked on the development of Mobil 1 full synthetic at Mobil in Beaumont, Texas. What did he use in his truck? The cheapest conventional oil he could find. Never had an engine problem.
 
All systems by law are required shut down power to the grid during a grid outage. It's called anti islanding protection.

Most systems will still provide power to the home.
Interesting. Mine does not. Panels shutdown.
 
No matter how expensive it may seem to have the oil changed it is nothing compared to replacing the car or the engine because it just gave out because it became all clogged up with sludge.
And despite me harping to DS to change, or at minimum CHECK his oil for MONTHS, he didn't, drove 15 miles with the oil light on, and has basically trashed his engine
 
EV's is a totally different discussion and you can find a few older threads on here. Generally seems like those who have an EV think they are wonderful/amazing and can't understand that where/how far they drive might not be the same as everyone else.

Or the people who have not yet experienced an EV think that every "truth" they have heard about an EV is true.

The inability to see the other view point goes both ways.
Chiming in on this. I am a diehard SUV driver. I have a diesel Yukon which gets 25-27 mph. My best friend could not be more opposite lol. She has a Prius Prime and her husband drives a Chevy Bolt. Her Prius is a hybrid so can be just electric then switch to gas. This would be ideal for me, but like, in a big SUV lol. Neither of them drive much and their kids aren't in sports that require them to go all over the place, and they don't really vacation either, so EVs work great for them. My kids on the other hand are both in different sports, and we frequently drive to tournaments over 200 miles away. Those tournaments are never in places where there are chargers tho. Wrestling tends to be in high school gyms in small towns here. For us, an EV would be much more difficult, because while there are some with a 400 mile range, thats like depending on actually getting an extra 60 miles after your low fuel light comes on lol. It's possible, but most of us don't take that chance. I am hopeful that eventually the infrastructure gets to the point where chargers are everywhere, but for those who live rurally or travel a lot in rural destinations, we aren't there yet. And while I know there are probably chargers available along the route somewhere, but we don't want to add that much extra time to an already horribly long day.

Even taking the range anxiety out of the equation there's this. In the same week, they both hit small deer on a county road. One of them was on gravel, so maybe 40 mph. The other one was maybe at 50 mph. The damage to the batteries alone in the Prius was enough to total out the car. It was only 2 year old with like 10K miles. Took her almost 6 months to find another one to replace it, and the insurance payout was not enough to cover the full cost of a new(ish) one. Her husbands wasn't totaled, but it was close. 2 weeks after that, I hit a deer at around 60. It broke my grill. That's it. I drove it around for 2 months before I got it fixed. So it's not even just the worry about will the battery need to be replaced before I am ready to get rid of the car. There are things outside of warranty issues to be considered as well. Usually when people mention the cost of the batteries, the response is most people will never have a car long enough to have to worry about it. But stuff happens. And I know many people don't carry full coverage insurance if their car is paid off, esp now when money is tight. So if you hit a deer, or are hit by an uninsured motorist, it could certainly be very expensive to fix.

I think this is a thing where unless you have experienced a thing, you can't really get it. Like I have always lived in a rural area. I cannot fathom driving less than 20K miles a year, or having everything I could possibly ever need in a 10 mile radius. Heck my kids school isn't even in a 10 mile radius. People who have always lived in metropolitan areas have a hard time (or seem to) in understanding that many of us do often travel farther than an EV can go in a day, and that there aren't chargers at our destination. Or that people do that often enough that it is a valid concern.

Everybody had a different experience but logically what would running clean oil through a dirty filter have for a benefit. On the other hand using a clean filter to filter dirty oil, might have some advantage. At least that was the thought back then from everyone that I knew, but I always change the filter when I drained the oil. It just always made more sense to me and a filter was not all that expensive. I bought my first new car in 1970. It was a Buick Skylark with a 350ci engine. ($3100 can you imagine that) I got that to go for 130,000 miles when most cars back then were retired at 80,000 miles at the most. It still ran great but the seven, heavy salt Vermont winters did the body and frame in.
 
I just go when my light comes on and tells me it's time, which is usually about 7000 miles. We have a truck that isn't really driven much and it has probably gone several years between oil changes at times.
 
8 years, 100,000 miles for all automakers.
How does this effect depreciation? We haven't had this sort of car in the world that long but how does this work on the resale market? Like I have a 10 YO civic that still runs and has a decent resale that could get me into another car. How would it work with an EV. Does the owner just willingly eat the battery loss on top of depreciation or are these things so amazing they hold the value and the resale can absorb the battery expense? IS the rest of the vehicle so amazing it is like new and no replacement? I imagine new parts could be tough without a ton of generics on the scene, maybe they are out and about or are they still so new its all OEM this and OEM that?



All these things factor into vehicle decisions for most people

I don't know how rural you live but I know I frequently visit middle Georgia, and I don't think you can get much more rural and isolated than middle Georgia. Often spending weeks at a time there visiting family. I drive right at 20,000 miles a year and my wife another 8,000. My cost for that is about $600 a year in electricity. If I drove those same 28000 miles at 25 MPG I would be looking at $4000+. I'll take that $3400 a year in savings and go on vacation.

Charging in middle Georgia was annoying but is now a breeze. The same for our trips to Panama City Beach. Trips there required lots of planning because there was NO DCFC but now there are several options.

Now that the Tesla Supercharger network has opened up to Ford EV I no longer feel the need to do any sort of trip planning for charging when taking a road trip anywhere in the southeast. Any further than that and I would just fly but people drive EV across the country every day. I know I am 50 miles or less at the vast majority of times from a compatible and working DCFC. The built in route planning or the route planning in Apple maps will take me to a charger if needed.

As for repair times and costs, they currently stink for virtually any newer car. There are so many sensors to support lane keeping, adaptive cruise control, parking, etc, that the slightest bump causes $10,000 or more in damage. Set off an airbag and the car is totaled no matter what energy is used to drive the wheels.

Cars are designed to sacrifice themselves to save the occupants.

There are hundreds of thousands of rural EV drivers who drive everyday. I see more and more in rural Georgia when visiting my family.

On the sports kids theme, my neighbors son plays travel lacrosse. One of the other parents on the team rents a Tesla for every sports road trip because he has found it cheaper to rent an EV and drive than drive his own Tahoe and pay for gas and wear and tear. So far he has driven from Georgia to Maryland, Virginia, North Carolina, New Jersey, and Pennsylvania. All as someone who does not own an EV and has not had any issues. Another parent saw his success and thought he would do the same. He rented a Chevy Bolt, as a non EV owner did no research about public charging, and ended up having to abandon the car part way and fly the rest of the way. So yeah, not for everyone.

As you said:
I think this is a thing where unless you have experienced a thing, you can't really get it.

That is very true for many people and EV. Many people are not going to believe driving an EV is possible for their lifestyle until they see a friend or neighbor that has already switched and lives a similar lifestyle.

As for the diehard fullsize SUV in you, I have been working on convincing my wife that we should look at the KIA EV9. Dimensionally it is very similar to a regular Yukon but only has the option for 7 and not 8. All for very similar pricing but far cheaper operating costs in favor of the EV9.

Cars are depreciating assets, EV are no different.

The Tesla Model S has been around for 12 years.

Searching online I see 2012 Tesla Model S near me listed for sale in the $12,000 to $25,000 price range. The list price would have been $60,000 to $100,000 depending on model. I assume the $12,000 ones are the $60,000 and the $25,000 are the $100,000 ones.

The federal tax credit does influence EV depreciation. A car is expected to lose 20% or more of its value the first year. An EV that qualified for the full $7500 federal tax credit will generally have that taken into account for the used value making the first year depreciation more.
 
I went from being an every other month (due to miles) to a once a year (due to time).

Years ago I went by the 3,000 mile rule, then moved into 3-5,000 when most of the driving shifted to more of a highway type situation. That period was decades of every other month changes. I did them myself, until I purchased a vehicle that included lifetime oil changes.

Now my current car uses synthetic and the owners manual says to go by the sensor, within something like 600 or 1000 miles of when the system says to change it. But I read elsewhere that the manufacturer recommends 7500 miles. I am not sure if the sensor is just a timer countdown type thing, as the percentages shown seem to mesh pretty closely to the months since the last change (such as 50% at six months). But have been basically going right around the 1 year mark now anyway.
 
Awesome, I find myself wondering though, how long is battery life? Is it expensive to replace? Hoping they got this figured out, it is the biggest deterrent for me.
DH's car has about 220k miles on it, no problems with batteries. He's got an older battery technology, too. The newer batteries are expected to last a good million miles.
 
EV's is a totally different discussion and you can find a few older threads on here. Generally seems like those who have an EV think they are wonderful/amazing and can't understand that where/how far they drive might not be the same as everyone else.
We take cross country trips on a fairly regular basis. We drive 200+ miles one way to see family on an even more regular basis. If that's not as far as most people drive, I guess an electric car wouldn't work for them...

I live in the kind of rural area where my kids school has less than 800 kids pre-k-12th. And 85-90% of those kids live on gravel roads. We quite frequently travel to tournaments 2-3 hours away and never see an interstate. There certainly aren't chargers in the school parking lots when we reach our destination, and why would there be when the normal users of that lot live in the district and wouldn't need to charge after driving to the school. Even my friend who has 2 EVs admits they wouldn't work for us. It's great that they work for many, many people. But that doesn't mean they are a perfect fit for everyone. Like many other things in life, cars are not one size fits all. There is one public charger in the town I work in. Most towns around here are like that. Heck, even the capital city in this state only has 4 charging stations. 2 at car dealerships, and 2 at hotels.

We also tow a boat and a camper(not at the same time obv). That drops the range of an EV by about half. So having to charge every 150 miles or so? That adds a considerable amount of time to a trip.

Like I said before, I hit a deer at 60 mph in my yukon that was less than 6 months old just a few months ago. $1500 in damage. Not even close to 10K. Compared to totaling her car out at 40 mph. Those batteries are pretty pricy if you have to replace them for non warranty reasons.

I would totally love a hybrid yukon xl. I'd love to have that option for my daily drive. But just an ev wouldn't work for our family at this time. Like I just can't see getting my kids up at 4 am to drive to a tournament, having them play for several hours, then have to go sit somewhere else for an hour or so while waiting for my car to charge so we can make it back home. Now if your route takes you mainly on the interstate, then it's probably way more convenient to find a place to charge along the way. Hopefully one day we will be there, where it's totally reasonable and feasible for everyone to drive an EV. We just aren't there yet where I live, and even the die hard EV lovers where I live admit that. They are just in a stage of life where it works for them.

Or that people do that often enough that it is a valid concern.
I live in the middle of basically nowhere. It's 15 miles to a small town, 20+ miles to a larger, and a good 50 miles to a city. If I want to go anywhere, it's a drive. I do drive a Tesla - I wouldn't have bought an electric car that I couldn't find charging for. Our very first long trip was a little hairy with the charging situation, but in the 7 years since then, we haven't had a problem finding a charger somewhere, and we've had many chargers added to the routes we drive most often. On some routes, it takes a little longer than others. Sometimes it's an overnight charge at a hotel's destination charger. Heck, you can find free charging at hospitals quite often - it's not fast, but it works. There are also people that share their home chargers, and apps that will help you find them. I don't have an ICE vehicle to fall back on, and I don't sit at home. If you don't want to consider it, that's your choice. BUT - "I think this is a thing where unless you have experienced a thing, you can't really get it."
