I use a 20w60 (full zinc) performance mineral oil and the 'long' Chev' specific oil filter in my 1997 5.7GL. I also use a 75w90 full synthetic GL-5 rated gear oil in my Volvo Penta SX leg. |

Volvo used to recommend a syn straight 30, now they recommend a syn 10w/40. You could use HD straight 30 like Pennzoil Marine. Then there is the Merc/Quicksilver 25/40 that is actually blended for marine inboard use... |

A 10w40 is a very low viscosity to use in a V8 Chev! ![]() Oil shears & thins out with fuel dilution faster than a car, due to larger engine tolerances & mechanical load. Speak to any engine builder that specialises in V8's and marine use. They will mostly always recommend a thicker viscosity index. p.s. I do this stuff for a living. ![]() |
