I own a 2002 Chevy Avalanche and have run Mobil One since the first oil change.Currently I have 438,000 miles on my vechile and it is still the original motor.

[This review was collected as part of a promotion.] We change our own oil on our cars. Husband is a mechanic. It saves us tons bgg of money and mobil 1 is the top of the line oil. Long engine life for a synthetic oil.

I own an express oil change I do a lot of oil change and this is the best for my customers they happy and the cars are running like new I keep it clean I love it

Have used this product in my last 5 corvettes and can say that in my opinion it is a very good product and does exactly as advertised. I have never entertained the thought of another brand as this product has excelled in my opinion.

I've have used Mobil One 5W20 since purchase of my new 2011 Toyota Camary , I was shocked as I found out ( damaged oil pan ) leaked out ALL ENGINE OIL from a returned trip from Texas to California!!! Over 1800 miles with no Damage to engine!!

Have had excellent results using this product. It has given me confidence in engine protection and good results in fuel economy and no significant oil usage between oil changes.

have 02 f 150 w/ 5.4 engine purchased brand new had 340 miles have used only Mobile 1 full synthetic only Today i have 472,246 on it , engine still runs like new GREAT oil Thanks Mobile 1

Change oil every 20,000 miles on my last 7 Toyotas and Scions,Every 5000 miles i change the mobil 1 fliter. with new one.Always use Mobil 1 oil and Fliters

I own a 2005 car with 379,000 miles on it. I purchased the car new and used Mobil 1 on every oil change. It is the original engine and runs almost as smooth as the day I purchased it. Would you like to do an inspection on my engine?

I have 2001 Lexus RX300 which my miles its already been 380,000 and my car has excellent performance until now i had been using Mobil 1 5W-30 since the first change oil until now.
