this is what I'm talking about. They also have one that is for every 5K, and one for every 7.5K

 

if it's mobil 1 saying you don't need to do oil change every 3k miles, would you follow it?

they have extended performance oil on 5w30, 10w30...etc, labeled oil change period: 15000 miles.

is that the fact that you just trust mobil more than any other brands tha you don't see much in parts stores?

or

is it becuz you think it must be right to do oil change frequently?

or

is it becuz mobil didn't have such extended performance oil in the market so you believe less frequent oil change will hurt your motor even there were already some advance developed motor oil available in the market that were proven to protect your motor longer and better?

 

What the hell is this guy talking about???? I just wanna know what people think about it, to see if I should try it or not. I hope your previous 56 posts weren't that freaky... and is it just me or does the final "OR" not make much sense.

 

I change my oil every 7.5k. It's 5W-30 synt Mobil1.
So far it's fine on both vehicles for about 30-35k miles each.

 

i wasn't talkin about you. if the OR thing freaks you out, i appologize

 

i just went and changed my oil and used that "ADAVANCE AUTO" oil, that is compared with i think valvoline or soemthing, i used that 10w-40! and my car has been driving OK, normal. and I CHANGE MY CAR"S OIL every 2,500 miles.... adn its still black dirty oil. so i dont know about that 7.5K oil change.......i want to do that SEAFOAM stuff but ppl said if u dont need it dont do it, because it might mess up ur engine... and HOW DO I KONW IF IT NEED THE SEAFOAM stuff..... MORE INFO plz...

thanx
MOE~~

 

remember my car got 165K....

 

Should have went 5w-30.

 

why? that oil is really tTHIN and i got alot of miles. my seals are not that new... thats what i heard....... is it true or not???

 

Increased wear at startup with a 10w, reduced oil pressure running with a 40 weight oil (a little more wear).

I would at least go to a 10w-30 next time you change.
