pls. dudes will u help me about one thing..........

what kind of oil are we SUPPOSE to use on our cars? 5w-30 or 5w-20 ?
im leaving in a minute and im jus wondering if u could respond because i have to go in a few minutes and when i come back ill check back the answers and ill go straight to the oil change........ sorry for any inconvenience i just need some quick inputs... i would have done search but i found it hard to find its like a needle in a haystack..... i dont have enough time.

THANX IN ADVANCE

If you haven't changed your oil before then go with full synthetic, otherwise read your manual....[IMG]i/expressions/face-icon-small-disgusted.gif[/IMG]

5 w 20

You can use 5w30 if its warm out......5w20 is recommended and not avail in synthetic yet (that I know of)

Valvoline, Mobil, Pennzoil, and others make it in 5w20.....

You mean warm like Cali weather? I was thinking synthetic, and since you just said tht a 5w-30 would be ok if it's warm out, I may as well go syn with a 5w-30. By the way, is it ok to go synthetic on the first change?

Changing to syn. early is heavily debated. My best advice - change it often with good quality oil and filter.

IMO- first oil change is too soon.

That's what I did, I'm still cool...

The quick answer is:
5w-20

The long answer is:
read your manual P. 210

The numbers indicate weight of the oil. There used to be single weight oil.
The higher the number, the higher the viscosity and the thicker the oil.
While the 5 weight oil flows like cooking oil (thin), the 50 weight oil flows like cooled down lava (thick).

Lower weight oil will speed up oil flow at startup and minimized startup wear but will not provide enough protection when parts are under load.
Higher weight oil, being thicker, giving higher internal friction when coupled with near freezing battery will give you difficulty startup. (In the old days ppl use a lighter weight oil in winetr to aid startup.)
To accomodate both scenario, additives were added to lower the viscosity of a relatively thick base stock oil. We now see 5w-20, 5w-30, 5w-50 etc ...

The letter "w" in "5w-20" means winter.
An oil denoted 5w-20 means it flows like a #5 when cold (startup) and #20 when hot (engine warmed up).

An lighter weight oil is going to reduce internal friction and save you fuel.
