Great Oil

I have a 2018 Chevy Impala Premier & Chevy Colorado 4x4 4dr both with V-6 engines. I had the dealer drain the original oil and replace it with Mobil 1 5w-30 Oil. Previous vehicles had almost 325,000 miles each and I only used Mobil 1. I am a customer for life.

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

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

Mobile 1 is a great synthetic motor oil

I came from a large surface coal mining company and we were owned by a major oil company. We were bound to use their motor oils in our equipment. In thirty years of managing the maintenance department and overhauling and repairing all types of engines I can say that while the major oil companies oils were fine, but there is no comparison in the appearance of the inside of the engines with one that has ran Mobile 1. I recently rebuilt the engine in one of my Corvettes that had 150,000 miles on it. The motor had not failed and was torn down to repair oil leaking from both rear corners of the oil pan. The oil pan itself was at fault and no seal had failed. The engine was clean inside and all bearings looked as good as new. It was in remarkable shape and had used Mobile 1 from the factory till its repair. I would never consider any other motor oil in my Corvettes as long as Mobile 1 is available.

What the 5.7 Hemi needed

This is my 3rd oil change on my 2015. I have only 10,564 miles on this truck. And I finally found the oil made for my engine. Three oil changes sounds excessive for these few miles, But I was not satisfied with bulk oil or oil with the name synthetic blend. A mixture of conventional oil and synthetic. I noticed that 5.7 - Liter V8 HEMI MDS VVT Engine was not shifting right and struggled to switch from 8 cylinders to what ever the computer decides is needed at slower speeds. And the proof when I starting using Mobil 1 5W-20 I could tell the difference within 100 miles, The start up tappet sound is gone. my mileage went from 15.9 to 20.6 on the Eco. a gain of 4.7 mpg. And the real proof will be in a month or so the oil change minder should slow down the 100% to 0% oil change reminder. Better protection , lubricating the engine like it should, I have tested this on my other 3 vehicles and found that conventional oil or synthetic blend was not for me. I am finally convinced that my MDS engine was not a mistake.

Unparallelled product that is worthy of the price.

I purchased Mobil 1 Advanced Full Synthetic motor oil as a first-time buyer to this product and it is top-notch because my vehicle drives excellent and shifts great and as result: I am a fan for life with Mobil1 full synthetic motor oil and I do recommend this product for luxury vehicles, high-mileage vehicles, vehicles burns a lot of oil and sports cars.

The only oil I'll use!

Been using Mobil 1 in all my vehicles since 1980, the only exception being my old 2001 Ram Cummins and I ran 15w-40 Delvac in that for the entire 250K miles I owned it. Currently using Mobil 1 5W-20 in my 2017 Ram Hemi with a Mobil 1 filter and changing every 10K miles. I have the Mopar lifetime warranty on this truck and at 59 may be my last new truck. Hoping to get 500K on this engine and I know with Mobil 1 it will be possible!

Best Synthetic Oil

Ever since a friend introduced me to extended wear oil products from Mobil 1 I've been loving only having to change my oil once per year. Be sure to check it once a month in case you have to top off if your engine burns a bit of the oil, but otherwise if you're under 15k miles per year on your car like I am, no need to change it 2-3 times a year, once will do. I've been using this oil for most of the 11 years that I've owned my 2003 Suburban (and my VW Jetta, Toyota Corolla, and Hyundai Elantra -- rest of the family). I have over 100k miles in all of my cars (almost 200k in a couple) and they all purr like kittens. Feel confident in using this oil once per year

My engine’s love this stuff!

I own 3 vehicles. A 1998 Chevy K1500 5.7 Vortec, a 2018 Ford Mustang 2.3 EcoBoost, and a 2016 GMC Sierra Denali 1500 6.2 Ecotec (0W-20). I’ve tested every major brand of motor oil there is on these vehicles and none of them came close to comparing to Mobil 1! I would highly recommend this product to anyone that feels like they could benefit from a strong and smooth engine!

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.
