I have used Mobil 1 ever since it came out and have always been very happy with how clean my engine internals have stayed. On one car I had a head gasket leak at 200,000 miles and the mechanic called me in when he pulled the head off. He said take a look at the internals they look brand new!!! With the valve cover off everything did look brand new, no sludge or coatings of any kind and no discoloration from oil build up or staining either! He asked what oil I have used and I told him Mobil 1 !!

How can you beat Mobil 1 motor oil for $30.00 for a 6-pack.....fantastic Sam's deal !!

Good price for good quality oil will purchase again

Fast delivery..great savings

I bought this product many times it’s great

Just what I ordered and was delivered very quickly!

This oil has never failed us our cars and truck only use this type of oil.

Good deal and fast free shipping can’t beat that at Cosco

Always have to order on line, because the Dover De location never has it.

it's mobile one what do you expect? it's the best
