Rated 5 out of 5 by Excellent product! 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. December 24, 2015
Rated 5 out of 5 by THIS IS A THUMBS UP MOTOR OIL I never used anything less than Mobil 1 15/50 until I bought my 2010 Royota Tundra. I was very sceptical about using 0/20 Mobil 1. So while I was shopping for oil for my first oil change I called Mobil Oli and explained my difficulty about using a 0/20 motor oil. I bought my Tundra with 9,000 miles on it and it was out of warranty due to over 5 years. So I used the 0/20 Monil 1 and checked the oil level once a week for two months straight. Now that I realize the engine is not using oil, I made a decision to test this motor oil after 10,000 miles. I sent my sample to Blackstone Labortories, the same place I sent my Diesel engine motor oils. When I got my report back I was very happy to read that I could go another 2,000 miles. That tells me the motor oil is doing its job and then some. I use Mobil 1 0/20 Advanced Fuel Economy (the green label) and a good filter. So use the Mobil 1 oils with confidence April 7, 2015
Rated 5 out of 5 by Everything you wish for and more... This engine was a custom re-build from LC Engineering and has a stroker crank. After a break=in period I was anxious to get some Mobil 1 full synthetic into it. This 0W-30 was just what I was looking for. A modern oil that made the most of the rebuild and provided good cold start performance keeping in mind that it has forged pistons and a solid lifter cam. I am very happy. December 22, 2014
