Looking for oil for my 4.3L mercruiser. I got the block from a high mileage blazer, unknown history.
I had used rotella/delvac 15w-40 conventional oil in the 3.7l that it replaced. Wondering if I should continue that, switch to a supertech full synthetic for the same price, or ...
Filter was going to use a fram tg unless there's a better option.
Oil changed every season, probably 50-100 hours.
