Hello Scotty. I have a 5.3 L 2004 Yukon XL with 219,000 miles. Oil is getting past the piston rings, and using Lucas has helped substantially. I was wondering if I could do half oil half Lucas on my next oil change. (3 quarts Lucas, 3 quarts oil.) Is this too much, or is it possible? Truck has been neglected, which resulted in that problem. Thanks!

Well that is awful thick oil then probably too thick to lubricate it correctly if you live in a colder climate in the winter though if you lived in a hot place like Egypt it would probably be fine
