which oil do you use?

[LatinDragonXJC]

while on this topic i would like to know

is 93 octane ok for 2000 v6? I assume it is..and what would be a max octane rating to use safely?

and what would be the problems associated w/ using octane that is to high for a particular engine..?

that said i tried $15 of 93 octane in an empty tank this morning and it really seems like the idle is super smooth

is it me or would i get results like this from using high octane gas?

anyone have a good link to octane explanations/uses?

I dont think theres any such thing as too high an octane rating. A higher octane just means the gas combusts less easily, ensuring that it only combusts when sparked, rather than before the spark (which causes knocking). The higher you go, the more expensive it gets, expecially when you get over 94. Then your in racing gas realm, which can cost upwards of 5 bucks a gallon.

They dont sell 91 in Jersey - its 87, 89 and 93 only, so 93 has to be OK since we dont have an option in premium gas. Its only cost-effective to use as much octane as you need to prevent early combustion. Anything higher is preventing knock that wasnt going to happen anyways.

5SFE and 2AZ need 87+ by spec, and 1MZ/3MZ needs 91+. Cars are more prone to knock as they get older, so it might be wise to increase the octane rating as a car gets on in years. Telltale signs your knocking is slower acceleration than usual (Knock sensor should sense the knock and retard timing as to not knock, saving the engine).

Ive been putting 93 in my 5SFE since I got it 5 years ago. It hasnt balked at me. The extra octane is probably a waste of money, but its an old habit of mine.

Maybe in your area, down here in Jersey City......Ive only noticed premium to be 91. Maybe its because I go to a Hess station.
