I have a 2012 Silverado 4.8 with a few mods in the engine tune long tube headers and a camaro ss body throttle I was recommended by the guy who tune the truck and this full advance synthetic oil is amazing the engine runs way smoother and I got 117250 miles on it it responds way better now than it use to not only that I change to the mobil 1 oil filter that too is a good product I will highly recommended and there no way I change the brand no more on the truck. Mobil 1 oil and there filters are the best.

I drove for a limo company back in the 80's., and my boss used Mobil 1 in all of the vehicles, even his own personal vehicle. Back then even before the new extended performance oil he would change the oil every 15,000 miles. and never experienced an engine oil problem. I saw with my own eyes, these vehicles go 300-400,000 miles and still be running great when he sold them. i have used Mobil 1 products ever since.

[This review was collected as part of a promotion.] I don't think we would ever consider using a different product than this one. The quality is absolutely superb. I have not run into any problems ever with the engines we have used this oil in. We will continue with this product as long as we can.

This week we had to take the valve covers off my 2002 Jeep Grand Cherokee Limited. Finally had a valve stick & kick off a rocker arm after 250,000 miles. I bought this Jeep in 2007 with about 50,000 miles on it, & since then it has had nothing in it but Mobile 1. When we took off that valve cover, the cams & all still look new! No gunk anywhere, just clean oil soaking everything. Thank you Mobile 1 for keeping my Jeepy running to a quarter million miles, & longer after we fix the current issues ;)

I started using Mobil 1 back in 96 when I bought my 1996 Chevy C1500 pickup. right away, after the engine was broke in and had some mileage on it, I changed it to Mobil 1 Synthetic and no issues. After I sold the truck and brought a new 2002 Chevy Silverado with a 5.3Liter, I did the same thing. immediately switched over to Mobil 1 and I still have the truck and it has 135,000 miles on it and runs great, smooth idle and no leaks!! I have added two other cars to use Mobil 1 oil and I have a 09 Impala SS with a 5.3Liter and just bought a 2015 Fusion Titanium 2.0l turbo that are using Mobil 1 and the Mobile 1 oil filters. I go between 5000 to 6000 miles for the oils changes and to know I'm using this oil, I feel my engine is protected and gets through cold winters and hot/humid temps in the summers. I'll never use anything else, but Mobil 1 synthetic!!

Started using in Hawaii in 1977 in my 74 Volvo which required manual valve adjustments. Valve gallery stayed clean even with short mileage drives. Kept Volvo until 1986 and engine still ran smoothly with virtually no oil burning. Been using in all my vehicles since 1977. Do not compromise on engine oil; use Mobil 1.

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 first started using Mobil 1 when I bought my first Mercedes SLK in 2005. I drove that car for 13 years without any motor problems what so ever. In 2010, I purchased another Mercedes E550. I'm driving that car today without any motor issues. I've been using Mobil 1 in my lawn mowers, snow blower, and home generator for the past 10 years. !n 2017 I purchased a new Honda Ridgeline. I've been using Mobil 1 in it since the first oil change. Last year I purchased a new Corvette Stingray. Of course Mobil 1 again. I believe Mobil 1 keeps my engines cleaner and increases my gas mileage.in all of my cars. I recommend Mobile 1 for any 4 cycle motor.

I have used 5w-30 for our 2017 Chevy Malibu Premier 2.0l Turbo, and 5w-20 for our 2015 Chevy Colorado LT 2.5l engines since new. There have been no issues or oil usage on either engine, and the oil comes out in good shape when the oil meter tells us it's time for an oil change.; The oil changes come at 1 year for the truck and aprx. 10 months for the Malibu Turbo., and I feel these are very safe intervals with the Mobil1 Advanced Full Synthetic Oils. Thanks Mobil !

I first used Mobil 1 in my 1999 Toyota Camry, I used for 4 years, in 2019 I got 2007 Toyota Corolla till 2022 when I sold it with 32% increase of the original price, for 8 years I never experienced any engine issues. Mobil 1 has been safer and protector of All engine parts
