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.

Mobil1 5W-30 full synthetic with Dexos SN Plus is really an amazing motor oil. I tried it in both my Mercedes sedan and wife's GLE. It works much better than whatever 5W-40 the dealership had been putting in before. I noticed my engine heat gauge runs 1 tick mark lower that where it usually is and gets slightly better fuel economy.

I purchased a 2000 grand marquis in 2001 with 22,000 miles on it, changed the oil to Mobil 1 5W-30 fully synthetic oil and set it up on routine changes every 7500 miles. Today August 2019 I have 584,632 miles on it and its still running strong, with no major repairs to the engine. Oh yes, I went through many spark plugs, coils, belts, hoses and lots of tires but no repairs to the motor. I give this credit to Mobil 1 oil.

I bought this oil to replace old oil in my daughter's 2009 Chevrolet Suburban, 3 days later( approximately 75 miles ). She called me to come help her because she was broke down at the end of the road I live on. I soon discovered the piston sticking out the engine block. Engine oil life is still at 100%. Very DISSATISFIED

[This review was collected as part of a promotion.] I changed my oil to Mobil 1™ 5W-20 in my truck. I have a Toyota Tundra that I use very heavily. I hadn't used this oil in the past. Once I changed the oil I could almost immediately feel and hear the difference. This oil is super smooth, and my engine purrs. If you need a great oil, great protection for your beloved car or truck, this is the oil for you.

I have 345,000 plus miles on my 2007 Nissan Altima se, which was put in when my car first hit 10,000 miles!, this oil is second to no other as my car purrs like a kitten even after running my car with no oil on the dipstick several times, I do not recommend doing that but my belief is if I had anything but mobile 1 in its crankcase, that I would of been shopping for a new car, thanks mobile 1 , jerry b.

I have been using Mobil 1 Synthetic Oil since about 1987 after I installed a remanufactured short block Pontiac 400 engine into my 1976 Pontiac Grand Prix. Prior to that, the old engine -- using conventional oil -- would give that familiar GM "tick" sound of the valve lifters when the engine was started or was running. Mobil 1 was recommended to me by a very good mechanic friend of mine to use on my new, remanufactured engine to get the best performance and life span. After installing the engine and giving it the traditional break-in period, I moved to Mobil 1 and never heard the lifters again. I also noticed that the oil traveled to the top of the engine after start up faster than conventional oil, especially during cold weather starts (i.e.: the lifters sound disappeared quicker or was not heard at all). Furthermore, during extremely cold days, it seemed the engine turned over faster than before when using conventional oil. I attributed it to the superior flow characteristics of synthetic oil at colder temperatures. After these favorable experiences, I was completely sold on Mobil 1 and have been using it ever since for all my automotive and gasoline engine lubrication needs. I also use Mobil 1 for my gear oil lubrication in the differentials of my vehicles. I have even began to use it my riding lawn mower with a B&S 17HP engine. Per the B&S engine manual, synthetic oil can be used in place of conventional 30w oil. I moved to using Mobil 1 and can definitely tell a difference in the way the lawn mower engine runs and responds. If you have not begun to use Mobile 1, I would highly encourage that you do. With the ongoing high prices for automobiles and power equipment, Mobil 1 is one way you can protect your investment and get the maximum life span.

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!

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.

I have a 1999 Pontiac Trans Am WS6 with 114k miles. I just pulled the motor for some upgrades and I couldn't believe how clean the internals were. This is the first time this motor has been opened up. It's never been cleaned, flushed, etc. It has, however, never had anything but Mobil 1 Synthetic in it. After my experience so far, it'll never have anything else in it either.
