Folks...there is a reason why corvettes require this to maintain warranty. I have used Mobile One for the last 20 years. RECENTLY, I had a 2.0 L turbo buick regal. I never had any issues with it and sold it with 190,000 miles. The yound man I sold it to is still driving it 2 years later. I use it in my trucks, my two sports cars (Dodge Hemi 5.7 and Chevrolet Camaro), my lawn mowers and have not had one single engine problem or issue. I would call that an unparalleled success. Thanks to the Chemists and other folks who have put such an awesome product on the market!

This is the first time using Mobil1 Advanced Fuel Economy Full Synthetic motor oil and so far it has been working great! I bought 0W-20 as this is the one recommended for my wife's 2014 Lexus IS250 (2.5L) and is also the first time I do the oil change on her car. We recently got married and she had been taking it to either the dealership or to another well-known shop and they were charging her waaaaay too much (avg. $100). I spent less than half of that and did it myself. Needless to say, now we know what type of oil her car has and pairing it with the Mobil1 oil filter, boy I can tell the difference. Car just feels smoother on the highway. I'll definitely continue using Mobil1 Advanced Fuel Economy from here on out.

I use Mobil 1 synthetic oil in my 2011 Dodge Nitro 4.0 litre engine, my owners manual say change the oil every 8000 miles or 6 months. Your website recommends I use Mobil Super Synthetic 10w30 since it will go 7500 miles. I dont mind pushing my engine to 10,000 miles between oil changes with Mobil1 because I know it will protect my engine, I check my oil every week and it never goes down . a testament to how good your oil is.

Nearing 111,000 miles on a 2010 Toyota Camry LE with the 2AR-FE 4-cylinder engine, vehicle goes 5-6K miles between oil changes; oil loss per change interval is less than a quarter-quart. Cold weather start-ups are excellent. Oil is also used in a 2012 RAV4 (also the 2AR-FE 4-cyl. engine) and a 2013 Corolla (2ZR-FE 4-cyl.) with excellent results. All three vehicles return excellent Blackstone Labs reports. I have zero complaints with the 0W-20 AFE grade oil and will continue to use it with very high confidence.

[This review was collected as part of a promotion.] As a person who drives a lot I can always feel whenever my car needs a oil change because my gas seems to go out faster and my car drives weird but being able to change my car’s oil with the Mobil 1 0W-20 Advanced Fuel Economy was a great option and decision I feel like after my oil change my car drives so smoothly and the best part is my gas last longer again

[This review was collected as part of a promotion.] I have been using Mobile 1 for years in all my cars. This Advanced Fuel Economy formula enhances your car’s fuel economy. I get way more miles on this synthetic oil and have never had any oil related issues. It’s known for running cool to reduce the engine’s heat which is why I switched to this after having heating issues in a car we had. If you want the best for your car, this is what you need.

[This review was collected as part of a promotion.] Perfect for my 2007 BMW 330i. No valve noise after i start the cold engine. In hot run perfect and have too much power for twin turbo. I recomended this 0w-40 mobil 1 full syntetic motor oil. it's the only oil i use.

I have 2 Subaru 2009 Foresters that I bought new. Changed both of them over at 10,000 miles to Mobil 1 synthetic oil and Mobil 1 filters. From then I changed oil and filters at 10,000 mile intervals. Now both are at about 200,000 miles each and running strong. No smoke or engine problems.

I have been using Mobil 1 since I became aware of it back in 1977. I had a 77 Ford F150 4x4 that saw some pretty rough use. I never had an engine problem. I sold my truck to a friend who didn't maintain it & something broke in the engine so he had his mechanic look at it. His mechanic told him that the motor had been rebuilt so he called me to see when I replaced the engine as it was too clean. When I told him it was the original engine they did not believe me, but yes it was. That was way back when & Mobil 1 is the only oil I have used since & I have never had an engine problem related to oil. Thanks Mobil 1.

[This review was collected as part of a promotion.] The Mobil 1 Advanced Fuel Economy is the quality oil you would expect from Mobil. The oil has provide advanced engine protection and I have noticed better fuel economy. My car is running noticeable smoother. Highly recommend!
