In my company F150 it’s done when the light comes on, I think around 8K. I run Motorcraft synthetic blend.

In my Jeep I do it every 5K since that about all I put on it in a year. I run Mobil 1 synthetic in it.

I use Amsoil Sig Series and their EA filters, so I go 15K and replace the filter and add a quart. I do an oil and filter change at 30K. I could go much longer if I installed the bypass filter system, but I'm getting old and lazy. My SUV has 250K and my truck has over 360K on it. Wife's car has around 70K.

Agreed. They say the 3k-5k interval to make more money.

A poster years ago posted this lab sheet for Mobil 1 Extended Performance after 12k miles in his Sierra with 102k miles. The lab said it would probably be good for another 2k miles. So, after seeing that Mobil 1 EP is all I use. I change when the computer oil life monitor tells me to, which is generally around 10k miles.

You talking about diesel powered rigs? Because that's a different story.

My auto tech shop owners write up (been a customer of his 25+ years) on his philosophy on vehicle oil change, and an good explanation that oils today do far more than just lubricate metal parts in the engine.

He’s also a big advocate of DYIers doing their own oil changes to insure a good filter is being used on their vehicle (usually OEM) and the same brand/type of oil is used with each and every oil change.

Conventional oil has a much higher detergent package than synthetics. This cause a conventional oil to clean out the “gunk” and create sludge and oil loss.


Synthetic base stocks are naturally more resistant to oxidation so they don't need the extra additives that conventional oils are blended with. Also, the oil specs have been increasing the detergency requirements for years so they all will clean out the gunk. They all will also produce less gunk to begin with which means switching back and forth doesn't matter. As far as synthetic oils being a waste of money, that is entirely a matter of the application. I prefer the better shear stability and and higher TBN since one of my vehicles is severe service and the other is an infrequently driven supercharged V8.

Maybe I'm in the minority, but oil and filters are cheap in the grand scheme of things. Not something I really care to push when I can get a decent oil change and rotate the treads for less than 75 bucks.

Most you baws probably spend that on cold ones in a weekend.

You're right, but oil life monitors on vehicles are damn good these days. Changing the oil and filters with OEM spec stuff when the light comes on is still being conservative. The light in my truck (18 F250 gas) has never come on before 7k miles.

I agree but I bet the issue for most on this board is not a matter of cost but rather the inconvenience, either doing it yourself or waiting around for a good shop to do it for you.

But really there is no cheaper maintenance activity you can do on a vehicle to lessen the risk of high $ repairs down the road than changing oil, and fluids in general (radiator, transmission, etc), at regular intervals. I bet many repairs like leaking rear main seals, valve cover gaskets, etc people don’t even associate with infrequent oil changes.

I get to put a fresh quart in every 3k because of this. I still generally change it at 6k, because of how I run it

Synthetics do have higher detergent packages now a days if you are buying a major brand but most quick lubes have a synthetic house brand that does not have the high detergent package.

And, yes I totally agree that it depends on the application. I run synthetic in my truck but I drive 50k miles a year.

yep, no tools. And also don't have to worry about cross threading drain pan bolt holes. I pay $28 for mine online.
