A 5.3 L V8 Chevrolet engine typically requires 5W-30 motor oil for optimal performance. This viscosity provides good protection and efficiency across a range of temperatures. Always refer to the owner's manual for specific recommendations based on the model year and driving conditions.
5W30 weight
5/30 it should say on your oil cap
standard 5w-30 is recommended for this engine
On the oil cap it says "5 W 30".
10w30 in the winter time---- 20w50 in the summer time.
10w30 is what I would recommend for a 8 year old engine.
The manufacturer recommended 10W-30 weight oil in the 1979 Chevrolet Corvette. A heavier weight oil can be used in and older engine.
5W30 weight ONLY. Gastrol and kendell brands are a real good oil to use.
Normally 5 quarts with the filter.
