For me, mobile one works great, the oil stays cleaner and last longer in both of my cars !

Oil change @ 5000 miles to keep it running great !

We like the performance of Mobil 1 and it is the only oil we use in our vehicles.

Have been using for 22 years and have 1010000 miles on my wife's 2000 RAV 4 change every 5000 miles and does not burn any oil, don't have to all oil at any time

I bought my Chevy HHR SS new in April 2008 and it came from the factory with Mobil1 5w30 and has only used the same for over 8.5 years now!! We have 65000 miles on our car,runs strong and quick(the turbo helps) and thankyou Mobil1 !!!!!!!!!!!

Been using Mobil 1 synthetic for 26 years in many vehicles. Have had several vehicle with 450k. Never an engine failure. Worth every cent. Use in gm trucks, vet, and harley. Would not use another brand. tom k, virginia

I have been using this oil for over 100,000 miles at speeds up to 130 mph, and on the freeways of SoCal. Best oil I have ever used. When changing oil it still has good color not even close to being black.

I use this to keep my cars protected. My drag car and my track car are changed at normal intervals but the added protection keeps the engines in great shape and is worth the little extra cost on high performance cars.

I use this oil in my 2006 Jeep Liberty been using Mobil 1 since 200 miles now has 119,000 on it. I usually change 2 times a year which is about 7,500 miles but I drive in town and more than average idling. Will use in next vehicle I buy in 6 months.

My Dad delivered Mobil products for 40 years. I use Mobil 1 EP in my 5 cars and 3 mowers and never had a failure or engine that burned oil with once a year changes. You can't ask for more than that!
