96 valiant vip boat v8 5.7 motor chevy?

Question

i wanna know if any one knows what kind of oil i could put in this boat and how many quarts for the summer thanks in advance

Answer 1

It should take around 5-6 liters of oil and a 15/40 grade should be ok as unlike a "car" engine most marine engines run at a constant speed for long periods of time without too much stress on the engine.

Castrol GTX2 or similar will do the trick

Answer 2

being a 5.7 you would use the same amount as in its auto counter part. BUT do not use regular auto oils. Use marine oils only. For marine oils are specifically designed for the stresses that are put on marine engines  I use Quicksilver 25w-40 in mine.
