May I know which brand do you guys use?

I am using Motul V300 10w-40...is it good? Thanks~~

Location, Location, Location.

5w30 or 0w30 (some operation temp) but, Location.

everyones opinion is different ..

i use mobil 1 sythetic .. its a daily driver .. so no need for anything fancy ..

i change it at about every 3000 miles..

Search, Grasshopper. Many many threads on this.

Consensus is the top 3 are probably Amsoil (my personal choice), German Castrol and Mobil1. However, if you change oil and filter every 3000, it doesn't really matter.

The oily kind. The oilier the better

Im using 10w-30 is this ok im in California.
Los angeles to be exact.

Just got a case (6 qts of Mobile 1 Synthetic 5w30) at BJ's wholesale for $35.99 - $10 instant off (with coupon) = $25.99

Damn cheap for 6 quarts. Walmart sells 5 quart jugs for $26.

I run Castrol Conventional ever since i was 16.

I've never jumped on the Synthetic motor oils. I've never quite bought into the fact that it's that much better

I'm in Granada Hills and 10w30 is good for out here. If you ever move to a state that has below freezing weather, switch to 5w30.

Change it every 3k miles and it doesn't matter what oil you use. I use mobil 1 every 7500 miles. If you want to go more than 10k miles you may want to use the higher end oils mentioned above.

M1 15w50 and my car takes ~7qts. Oil changes are not cheap.

thank you guys....i live in Hong Kong, quite high humidity and hot in summer...thank you....
