Hi All,
I have the ability to get either of these oils at Costco here in the valley and the difference in price is about $4-5 dollars a jug. The 15w40 is about $9ish and the 5w40 is $14ish a gallon. Since the difference is so minimal between the two would it be better for me to use the 5w40 synthetic or would you think I should just use the 15w40? If the price wasn't so close I would not bother but I thought I should get some input. Thank you.
