Thread: oil change schedule

I go about 5,000 miles and then change it. I was supposed to change it yesterday.

moon do run conventional/synthetic/blend?

I use synthetic (like most everyone elseo n here I'm sure) so I do it every 5k miles.

i do it every 3k since i can do it for free. I dont trust the oil life monitors. We get them a lot that have like 20% left and they already went 8k. It suposed to be based on how you drive but some will let you go to 10k between oil changes. I dont care how you drive thats too long

Every 3,000 miles on the dot. Mobil 1 synthetic

I run synthetic. Mobil 1

I also go 5k... I use Valvoline 5w30 synthetic with a K&N filter

^I will NEVER use anything but a k&n wrench on filter.

yeah it is so nice to just wrench it off and not deal with a filter wrench.... It is worth the extra money.

never had any problems and i got 210,xxx miles
my dad has done the same and has 240,xxx miles on his 94 burban

I stopped using fram filters after having 2 of em collapse on a ford ranger and an old alero. That was enough to scare the crap out of me. I usually go with mobil filters or if i cant find em then whatever the OE brand is (delco, motorcraft, mopar, etc).

As for oil changing schedule, 3,000 if conventional oil, 5,000 if synthetic. Normally I only run Mobil 1 in all my vehicles (unless i can find AMS Oil) but in the blazer due to its age i run Valvoline Max Life just to keep the seals in good shape, especially since i dont drive it that often.

Penzoil full synthetic high mileage every 3-3.5k miles.

I've always been a little sketch on Penzoil products. Had issues with rough idle on vehicles with it. My truck specifically was running penzoil synthetic when the original owner had it and it idled a little rough when i bought it (mostly when cold, after it warmed it it went away). Changed to mobil 1 and the funny idle went right away. Thought it was old oil but checked the service record and the penzoil was put in right before i bought it.
