Only oil I now buy for my vehicles.

I used to use dinosaur oil and changed at 2000-3000 mile intervals. Back in 2012 I bought a brand new Camaro, v6, and it called for blended oil and it needed to be GM/Dexos approved. The price of blended oil and full synthetic was the same so why not go with full synthetic instead. I traded the Camaro off a few years ago for a '17 Colorado with basically the same engine and it will get Mobile also. I am such a believer in Mobile 1 that I now go by the oil life meter and now run until it tells me to change which is between 4000 to 5000 miles. I will likely be a customer for the rest of my life.

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

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.

Mobil 1 oil and there filters are the best.

250,000 miles & still the cleanest engine

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 ;)

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.

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.

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.

I have a 1999 Yukon with over 993,000 miles

The first 600,000 took me 3 motors. On my fourth I switched to Mobile 1 and have almost 400,000 on the engine in it now. Wish I had learned about Mobile 1 sooner. Who do I contact to see if anyone wants to do some publicity on my truck Pictures upon request
