Aq271c engine oil

[Sam Jenkins]

Hi would 10w40 semi synthetic be suitable to use in this engine. I know the book states 10w30 but i cant source this oil
Cheers

Yes, that would be fine for your boat, maybe even better.

Can’t go wrong with shell rotella 15w-40. Been using it in my same era AQ231A for yrs, no problem. It’s cheap and has a wholesome additive package perfect for boats with solid lifters

I agree with Rotella T4 15w40
