"Every year I ponder whether I
"Every year I ponder whether I should use straight 30W or 10W-30 oil in my AQ130C? Most of my boating is done in warm weather (Sacramento, CA area) with air temps often being over 90 F and as high as the low 100's. Occaisionally I will do some fishing in the mountains with cold temps (30's and 40's) in the morning.
A mechanic once told me to just use straight 30W. The V/P manual says to use 10W-30 or 20W-40. I've read some comments about using 10W-30 in a marine engine which suggest that multi-weight oils can break down in a hard working marine engine.
What do you other AQ130C owners out there use in your engine?"
