Hello, I have some questions on oil again . Every year I seem think I should be using something different, so just want to check with you all. The 2 motors are '94 454's with about 860 hours on them. I've been using shell rotella straight 40 and I havent had any problems at all. I am in Boston, and alot of my friends are using a 15w-40. People say the benefit of the 15w - 40 is for colder starts. I'm not really doing much boating when its colder than 70, except for hauling out, winterizing, spring commisioning, etc .
My crusader book says use 40w, so I've stuck with that, and the Shell Rotella with NAPA 1515 filters. Should I just keep using it or make a switch? I notice the Shell Rotella 15w-40 is usually cheaper too. I have 3 gallons of 40w now that is probably enough to do both engines for my fall changes. I'm thinking maybe do one with that and switch the oil in the other motor? Or just wait until next fall and switch it all
thanks!
