You didn't change oil for three years or am I reading your post wrong?

Yes, sad to say life got very busy and I didn't get to drive it much.

Does that mean y'all will now kick me off the list?

Probably going to have all kinds of trouble with the bearings and things, huh? Guess I should buy a new engine now so I'm not stranded on the side of the road?

LOL, wait until KrazyK gets in here.

IDK what kind of punishment shall be administered for that. Maybe force you to park your car in Tenderloin at night with top off? LOL.

Thanks for posting this sample Don King...btw are you the real Don King? Post a pic of your hair to verify. HAHA I'm a long time boxing fan/boxer and love the screen name.

Your sample only helps to validate the point I have been making here for a long time now. For low mileage cars running synthetic oil(which includes most of our cars), long interval changes are quite acceptable as time alone does not degrade modern synthetic oils. Your IOA is just one of many that validate my theory.

+996. I've been in the same camp. Sludge is a byproduct of heat. If the car doesn't get heated, sludge isn't gonna form magically. As for acids attacking your parts, if good amount of additives are still present in your oil(partially determined by TBN test) then no need to worry either. Cars have been around a long time with older tech Dino oils with even more worse abuse from owners/collectors and a good majority of them are just fine.
Of course there are those that would pull the fire alarm at the first sign of a smell or get a full colonoscopy if their butt feels funny....

More data all on my 2003 C2 Cab, alas no turbo, the 2013 report is on Motul XS 5-40 changed at low miles while doing IMSB. The others are Mobil 0-40.

I'm so glad that a lot of these reports are coming out of the woodwork. If you guys don't mind reposting it in the thread I created in hopefully having a comprehensive collection of these in one spot. Thank you.
