Re: Use of Yanmar Oil versus store bought oil
Huge question. On my last purchase of a new Honda Accord, I bought a couple of cases of Honda engine oil, trans oil, and filters just in case there was ever a warranty problem.
I figured if I had the receipts I might have a better chance. The incremental cost difference was not a lot. Honda does not require their oil to be used, they just specify the type and weight. If I had a Yanmar I would follow their recommendations. The small difference in cost, if any, may be worth it?
