What kind of Oil?

[f1seb]

I tried to search the net and can't find anywhere what kind of oil goes into the 97 240SX. Is 10W-30 synthetic good enough or should I go with 5W-30 synthetic? And how many damn quarts do go in 4 or 5? Sorry I have no manual I bought the car used and the search feature doesn't work for me to search the forums.

10w-30 oil should be fine. The amount you use I think is 4 quarts. Just put in four and check the dipstick, but I'm pretty sure it's four. How many miles do you have?

ya, its 10w-30. there is no real reason to use synthetic, but if the car has it in there now then go ahead and use synthetic.

the engine takes 4-4.5 quarts

I use Amsoil 10w-30  synthetic.  Real nice stuff.
