Looking for a good quality, cheaper alternative to the mercury/quicksilver 25w-40 semi synthetic or Dino...preferably semi synthetic.
Looking to save (if I can) without sacrificing quality. It's for a stock mercruiser 496 ho 425 hp. This motor calls for 9 qts and I would like to change twice a season, this is why I'm looking for a cheaper alternative. It's probably a waste, but each oc will probably only be 25 hours. I'm trying to be extra prevntive of Fuel dilution and corrosion, so a marine approved oil is what I'm looking for.
I was thinking the mystik JT-4 25w-40 semi synthetic would be good but it doesn't look like my farm and fleet carries it.
I'm sure the 15w-40 diesel oils are going to be suggested, but do they have the corrosion protection?
Anybody know about the Sierra oils? I heard that since mercury's patent ran out that the Sierra 25w-40 actually has a better add package than the mercury...any truth?
Thanks
