This is just a brief starting point with basic Maintenance information that I got from a my Haynes manual. (This is not a how to information). I just wanted to share it with anyone who might need the information to do minor tune-ups, but most enthusiast here will already know this. The information with parenthesis came from gathered info from on the web.

Listed here are manufacturers recommendations at the time this manual was written.Manufacturers occasionally upgrade their fluid and lubricant,so check with your auto parts store for current recommendations.

Engine Oil:
Type: API grade "certified for gasoline engines"
Viscosity: depending on temperature
5w-30 oil for -20 and below to 100+ F (Basically 5w30 has a wider range) I sometimes use 0w30 but that's just me.
10w30 oil for 0 to 100+ F

Engine coolant 50/50 mixture of ethylene glycol based antifreeze and water

Fuel:Unleaded Gasoline 87+

Manual Transmission fluid:API GL-5 SAE 75w90 Gear Oil (some people still use GL-4)

Automatic Transmission fluid:Dexron 2 or M-111 ATF ( higher Dexron numbers' also fulfilling the specifications of the lower number fluids)

Brake clutch fluid: DOT 3/4 (According to Wikipedia,Brake fluids with different DOT ratings can not always be mixed. It must be of the same type, and at least the same rating. DOT 5.1 can replace DOT 4 and 3, DOT 4 can replace DOT 3. DOT 5 should not be mixed with any of these as mixing of glycol with silicone fluid may cause corrosion because of trapped moisture.)

Power Steering Fluid: Dexron 2 ATF ( higher Dexron numbers' also fulfilling the specifications of the lower number fluids)
