Rated 5 out of 5 by from More power, mileage, engine life, used since 1966 This oil does not burn until almost 450 degrees F. Still lubricating when others burn. My Honda 750F with Mobil1 was several bike lengths ahead of friends Honda 750 after changing to Mobil 1. Before they were pretty even. When I sold the bike 21 years later valves still did NOT need adjusting. Looked like new inside cylinder head. Smokey Unick dyno'd Nascar 355 Chevy, went from 303 to 333 hp on the dyno! Just by changing the oil! My Cadillac Northstar 300 hp still is clean inside, gets 30 mpg highway, has 80,000 miles using Mobil1 exclusively. 1978 VW Scirocco engine looked like new inside at 180,000 miles, good compression, was using one quart of oil every 1,500 miles.

Rated 5 out of 5 by from great engine longivity Been using Mobil 1 5W-30 in my 2000 Pontiac Montana, which I bought new, since about 30,000 miles and noticed the brown staining from conventional oil at the filler area. The car now has 340,000 and I still use the regular Mobil 1, not the high mileage, and still do not have to add any oil between changes at about 7,500 miles. I do the changes when the Pontiac oil change reminder comes on. When I change the oil, I look in the filler port and the engine is still clean and no sludge can be seen. Engine has never been apart except for the 3.4l intake manifold gasket failure, common on this engine I am highly satisfied with Mobil 1 and use it on my '84 Buick Riviera Convertable and '09 Chevy Avalanche

Rated 5 out of 5 by from Cadillac ATS 2.0 Turbo I have used Mobil 1 since birth in my Chevrolet Cruze 1.4 Turbo and Cadillac ATS. I drive a lot of miles. I like the confidence that Mobil 1 provides, especially concerning the oil life meter. Moreover, I drive at high speeds and this creates a lot of heat in turbocharged engines, especially in warmer climates. I am confident that the engineers have provided enough testing and adjustments to the standard formulation in order to offer the highest level of protection possible. I do not see any need for the extended performance formula. "Mobil 1 is what it is" and I believe if I really wanted to take the standard formula through 15k mile oil change intervals, it wouldn't let me down.

Rated 5 out of 5 by from The best engine oil. I've been using exclusively Mobil 1 full synthetic (5W30 and 5W20) in every vehicle I own and many others that I maintain on a regular basis since my dad taught me how to change oil nearly 20 years ago now. Simply put when performance and protection matter this is your best option for engine lubricant. The wear protection is second to none and you never have to worry about whether or not an OEM will question the oil if there is a warranty issue because this product is better than theirs or is their recommended choice for their premium vehicles. They also have great racing lubricants for protection under the most extreme and demanding of conditions. I am a believer in using this oil if you value protecting your vehicle's engine past the warranty period and want to see vehicles reach or exceed their engine's max service life.

Rated 5 out of 5 by from My 75k mile review in my ss I have had my 07 Cobalt SS since new using mobil 1 since day one. The car was daily driven and drag Raced normally​. Now the Last​ few years mostly driven spiritually on the weekends and still drag Raced​. My car has all stock internals engine has never been opened car is over 100hp more than it came stock. Compression is perfect no engine blow by and never shavings in my filter. Mobile 1 has done an amazing job protecting my engine and wouldn't trust any other brand. 75,000 hard miles and my engine is as healthy as new. What else could you ask for! Thanks Mobil 1

Rated 5 out of 5 by from Best Product for my toyota sienna 3.3 I switched from conventional oil in my Toyota Sienna to Mobil 1 5/30 at roughly 70K. I now know that conventional oil can cause sludge build up. Sludge is not a friend of any motor. I change my oil every 5K and also install a new Mobil 1 filter. My oil comes out a dark golden color--not black like the dyno oil did. The van actually uses no oil in 5K. It now has 130,000 miles on it and runs like new.

Rated 5 out of 5 by from 15W-50 I purchased a 1988 C 1500 ten years ago, the prior owners used Mobil 1 products when service came due. The engine has nearly 260K and runs like a new engine. I am meticulous about periodic maintenance on the truck, I put about 5000 miles a year on the truck and change the oil once a year, the oil has darkened but is still clean and very slick, not burned. I had to replace the fuel system due to a bad tank of gas about seven years ago. I had to take off the intake and took off the oil pan with the idea it would be a good time to clean it out with all those miles on it. To my surprise, the oil pan did not have any build up and looked new inside, I didn't have to clean it, I give the credit to the people at Mobil who have work hard and used their heads to make such a product and keep the company going, a personal thank you for your hard work and discipline

Rated 5 out of 5 by from Only the best I've used Mobile 1 oils exclusively in my performance cars and daily drivers for years. It always comes out as clean as it went in, and never have had an issue with sludge. Definitely the best oil if you want to take care of your engine.
