I follow the vehicle’s oil minder. On the 3.0TT Explorer, that’s right around 8,000 miles. On the F350, it’s about 8,000 miles. On the Odyssey, it’s about 8,000 miles. On the other hand, with the Beetle, it works out to be about 8,000 miles. Wanna guess about the Focus ST? Yep, about 8,000 miles.

Truck’s got 165,000, the Odyssey - 120,000. I’ve had five other vehicles I put over 150,000 miles on before I got bored with them, but no issues.

I’ve been using synthetic for 24 years and whatever oil filters. I have no time for 3,000 or 5,000 mile oil changes.

Also, my truck is a 10 speed auto and even at 80 mph never goes over 3K rpm. Usually shifts at 2.5. Most miles are highway miles.

In my daily driver, a Gladiator I change every 5K with synthetic oil
In my Diesel F-350 it’s done when it tells me to, also synthetic. That has ranged from 4000 to 8000 miles.
In my Porsche it’s once a year which is about 3000 miles, also synthetic.
In my Tesla….never! ;-)

I currently have free oil changes from Subaru until my car hits 36,000 miles. They do it every 6000 with synthetic. In my previous car, I was using synthetic and a good filter and going 10K miles. I drive a lot, but the kind of driving I do doesn't put a heavy load on the car. No problems.

Get an oil sample kit from Blackstone (free). Mid drain, fill the container up, then mail it to Blackstone and pay them their fee. They’ll tell you the state of the oil. Anything else is old wives tales, or the mfr. predicting this and that, which I’ll never trust.

The Blackstone solution is the only way to really know. But with my four cars that are all old, it would not be worth it to "know" for each car and customize an interval for each ride, esp. since as engines age with lots of miles, the metals and pollutants in the drained oil aren't worth worrying about any longer. So, I change the oil on all my cars at the same time, at 5k+ miles, with full synthetic and Wix standard filters (vice the "HD" extended drain interval variant filters). Since 5k may be a little overkill for old daily drivers, I buy my oil in bulk when it goes on sale and rack it up in my garage, not letting any bottle get more than about a year old if I can help it, since I can't predict sales on 5 qt bottles.

But, if I had a newer more exclusive type luxury or performance car or truck, I'd do the Blackstone trick to understand what would be going on for the vehicle as it relates to the way I drive it.

Wow!
I thought I was doing well with my '02 Nissan, at 330,000.

You guys are doing good.

I only have 240,000 or so on my '05 SRT-10.

I use Mobil-1 and change it every six months.

Changing oil gets tricky when it is more than two gallons.

Like many, I change oil in my vehicles according to mileage as recommended by the manufacturer. I have a 2001 Honda Accord with 400075 miles on it and it drives just as well today as it did in 2001. I change the oil every 3000 miles and follow all the other maintenance recommendations made by Honda.

At the local Honda dealer in Aug 2022. If I remember right the signage said it was/is owned by a local insurance agent.
