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 have been using Mobil 1 for years. This is the only synthetic oil I have ever used. Engine runs so smooth, awesome fuel economy, awesome performance. I will not use anything but Mobil 1 oil or differential oil.

My 2006 Camry is going strong at 220k. Have always changed at 15,000 mile between changes. I tell people they're changing their oil too often but they won't believe me.

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 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 !!!!!!!!!!!

I wasnt satisfied with this Product at all. It didnt last the expected mileage and to top it off I was short a quart when I did a new oil change. I used both the extended life oil and filter. I will stick with just the regular synthetic oil.

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!

I have no idea how this oil is different than other oils but i have to say im amazed that this oil makes my car run so smooth and my motor now has a very smooth idle !! I can tell my car really like this oil! Runs really nice in my Acura RSX

weird how some folks are melodramatic about motor oil. pick one that meets the specs, change it according to the factory manual and get over it.
