Oil change intervals

[GLM]

Cummins 5.9 L diesel owners manual recommends oil change at 29,000 miles or annually.

7500 miles, full synthetic in wife’s car and my Titan, semi synthetic in my F250, and pay to have it done.

Synthetic oil lasts forever, filters do not, I change about 12,000 cars per year. Change it at 5000 miles and you will never have an issue.

My 2015 Silverado change when oil life is around 10% on sensor.
my 1997 S10 I change every 10k and oil filter every 5k.
have 325,000 on it so far. Mobile 1 fulll synthetic

'BobistheOilGuy' is the forum to go to for anything lubrication related. You get facts there, not just opinions. This is where the oil geeks have fun.

For about any oil you can think of, there are UOA (Used Oil Analysis) data you can look at.

Why do manufacturers recommend 10,000 mile intervals? Because all of these UOAs are showing that the (synthetic) oil was still meeting all the parameters it was supposed to when the drain plug was pulled at 10,000 miles.

From what I've read on that forum, you really can't find a bad oil - meet the manufactures specs and you basically can't go wrong. The filter reviews (they cut apart a bunch of them), if I remember right, says there isn't a real difference between name brand & store brand.

I do my own changes too, alway have. It's cheap & easy. I was much more conservative until I found the forum above.

My wife's Kia calls for 8,000 mile oil changes, so that is what I do, with whatever synthetic oil is cheapest-I do use a Kia filter since 100,000 warranty. I'm also keeping every used filter until that warranty is up-if there was ever an engine issue and Kia said you didn't do oil changes like you're supposed to, I'll just say, which filter (and oil sample) do you want to do a UOA on?

Pay to have it done these days. Based on my research , I chose

Dino-oil every 5,000 miles
Synthetic every 10,000.

My Tundra is every 10K recommended by Toyota.

I tried changing the oil on my Tesla last week but still haven’t figured it out.

Dummy, look right below the spark plug wires.

I tried changing the oil on my Tesla last week but still haven’t figured it out.

The oil reservoir for Tesla is found in the bearing housing on the generator at the coal-fired power plant.

I start checking my oil at 5000 and if it starts getting
Dark I will change it...

I own an auto shop all the customers who wait till the oil minder tells them to change the oil have problems. Cam phasers on fords, lifters on gm’s , engines on some vehicles. All my customers that get synthetic oil changed at 5000 mile intervals never have issues. The oil change minder usually still shows 40% oil life left.

5k on the '15 Taco 4.0 with Mobil 1 and Toyota filter since new (now 73k miles), same on the 23 Mazda 2.5 n/a motor 'cause it's DI, with the best add pack synthetic oil I can regularly find on the shelf at Wal-Mart. So far that's Mobil 1 as well.

I do it myself, 17 chevy 2500, 4500 miles. Oil is cheap.

I agree. I do mine every 5,000 miles, almost religiously. The factory recs on this newest car state 8-10k. No way.

[Strummer]

I go 7500 on my wife’s car and shoot for 10k on my truck .

[deerslayer64d]

2015 F-250 6.7 dealership changed every 3k miles and tire rotation and fuel filter change every other oil change, some will say that’s over kill on oil changes but I see it as cheap insurance

[dustoffer]

Filter every 5k with oil and filler change at 10k, then filter at 5k, etc.
