Need information about owner's manual

[tugg]

I have a used 240sx that came without a owner's manual. Can someone tell me the octane to use, what oil is recommended? Also what should the psi on the tires be. Thanks.

its stated that you use 91 for the 240, "For max performance". But u can use 87, u get good mileage. oil is 5w-30 in cold temp, 10w-30/40 for reg. and 20w-50 for high temp. Mobil oil is the best. i used 20w-50 last oil change. psi according to what it had already is 35. Hope this helps u out. other specs should say somewhere in ur 240, glove compartment, gas lid, door, etc. Download a service manual from vsiev.

it is recommended 91 but if 91 isn't available, lower octane can be used. The psi on the tires depends on the tire; if it says max 25, you dont' want to put 35 psi.
