i was wondering what the best grade oil to use with the jdm h22a vtec. the guy who did my engine told me not to use syn. oil becasue the oil too thin and i am gonna burn it to quick. he recrement i use 10w-40 but the helms said 10w-30 so i was wondering what u guy think thx
or sould i use half syn/ half oil? the mixture one.

 

5w30 castrol is the best oil for the money. Royal Purple is pretty decent. Mobil 1 is good too, but overpriced.

 

im asking what the best oil regardless of money and sould i use syn or sould i not?

 

use syn
its no more than $5 more

would you pay $5 for every 3k miles to KNOW that you're putting good **** in your engine?

 

im gonna be running my car a lot, wouldent syn burn oil to quick because the oil too thin. i was thinking about 10w-40 semi syn?

 

I'd recommend using 10w30 syn oil.
