Ive got a question for you guys, checked the dipstick and oil looks a little low, had the boat serviced by Greg Shoemaker, they did the oil change and I know that he used Kendall Oil, but I dont know which weight was used. Im in Needles and I cant find Kendall here, what should I do? Can I add something similar to that? Looked through my paperwork from them and it doesnt specify the weight. Maybe one of you guys knows what those guys usually use for a relatively stock 454.
