Good quality oil .One of the best on the market

I have a 2008 Corolla, 185K miles, and it has only had GTX 5W30 for oil. Engine does not burn a drop, oil change internal 3500-4000, and various filters. I also have a 2014 Explorer, 180K miles, only saw GTX 5W20, also does not burn a drop, 4000K mile oil change interval. Coincidence? No - I have used GTX for over 40 years, and have never fried an engine - small block Chevys, Fords, Toyotas, Hondas, Jeeps.. The body and frame rot out long before the engine has any internal mechanical issues.I will continue to use GTX as long as possible. GDI engines might move me over to one of the Castrol Synthetics

Good price. Delivered intact and on time.

Same as buying off the shelf.
