I bought a couple newer jet skis this year that are powered by 4 stroke engines. My older skis all have 2 stroke engines and obviously don't have any oil to change. The manual with the newer skis isn't really that good and just says use a good 10w50 oil. But, it lists several other weights that would be okay. Anyway, the weight of the oil isn't my only question. Since one of them is a very high performance 250 hp supercharged four cylinder, wouldn't a high quality synthetic oil be better for it? The smaller of the two 4 stroke skis still has a 180 hp 1500cc engine. Needless to say, these engines are generally run pretty hard and sometimes are held wide open for long stretches.
I've noticed that some of the Amsoil diesel oil I have left says it's heavy duty diesel and marine oil. I assume that "marine" part would be for a diesel marine engine? Or, since the engines are worked so hard, would a gas engine benefit by having the higher TBN and other additives?
