High High Oil!

It says "high mileage" on the label but from what I can tell, this is brand new oil and never used. That aside, it's one of the better oils you can get for a car or small truck. You also don't have to change it as often as the cheap stuff. I still do but YOU don't have to. Seems to perform well if you drive all the time like I do.

Proven results using only Mobil 1 engine oil

I have been using this same oil for 140,000 plus miles on one vehicle with a 5.3L engine and 135,000 plus miles on another one with a 4.60L engine.I recently had the heads pulled off one vehicle and the mechanic could not believe the lack of carbon build up on the valves and head. When I told him what oil I was using he said don't change anything because he had never seen heads this clean with the mileage I had on it. Been using it on both vehicles since they were new. Prior vehicle had over 500,000 miles using the same oil with no history of any engine work performed. The 500,000 mile engine was changed at every 3,000 miles. This was prior to extended mileage oil being available. The other 2 get changed at every 5,000 miles using fully synthetic extended mileage (20,000) oil.

Outstanding quality product I've relied on for years for my 20-year old vehicle. With an excellent lowest price around, a great value which saved me probably $50 having the oil/filter changed.
