I had my oil changed yesterday and after they drained it they realized they did not have any 5W-20 so they used 5W-30 (This is Mobil 1 BTW). Will this have any negative effects ?

i think the manual says 5w-30....right? that's what i have in my car now...and it's also mobile 1.

I didn't look at the manual, the guy doing the oil change said it is supposed to use 5W-20 and he was out of it....I guess I shouldn't trust the oil change guy huh

I thought the manual said 10W 30.

i think 5w-30 has a wider range temperature tolerance. and since i'm in va, where it gets really hot and really cold, i use 5w-30.

I beleive the grade depends on which part of the country you live in. In Jersey, the Acura dealership puts 5W30 in my CL.

You people are insane.....5w30 is wayyyyy to thin for the environments that you live. It should only be used in environments that are cold all the time. Mobil-1 synthetic or 10w30 should be the only thing that goes into your engines.

Infamuz

Are you about that?

Infamuz

I thought the thinner the oil, the better for your car?

I believe thinner oil breaks down easier in higher temp. I live in NY so in the winter I use 5w-20 and 10w-30 in the summer.

Before you change your oil between season, Do you get your Oil flush, than change the different grade oil?

yeah, 5w30 is too thin for hot temps. Basically, if live in a hot environment like miami or arizona you should use something with a 15w. If you go with synthetic you'll be cover year round. Oil flush is good when you're switching.

I just drain the oil. No need for a flush. Just use the same brand.

Thanks for the info guys. Speakign of which I picked up a case of Mobil 1 for 23 dollars. What you think of that price?

BNut

They didn't have a viscosity guide on their web site. (Mobile 1 that is)

cl-driver

Mobil 1 (synthetic) normally costs about 4 to 5 dollars a quart in NY. So you got a prety good deal.

I got it from BJ's warehouse club.
