Oil Weight


Mobil 1 Advanced Full Synthetic, 15W-50, 5-Quart is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from 15W-50 I purchased a 1988 C 1500 ten years ago, the prior owners used Mobil 1 products when service came due. The engine has nearly 260K and runs like a new engine. I am meticulous about periodic maintenance on the truck, I put about 5000 miles a year on the truck and change the oil once a year, the oil has darkened but is still clean and very slick, not burned. I had to replace the fuel system due to a bad tank of gas about seven years ago. I had to take off the intake and took off the oil pan with the idea it would be a good time to clean it out with all those miles on it. To my surprise, the oil pan did not have any build up and looked new inside, I didn't have to clean it, I give the credit to the people at Mobil who have work hard and used their heads to make such a product and keep the company going, a personal thank you for your hard work and discipline
