[This review was collected as part of a promotion.] I change oil by myself in most of my cars and over the years I've used multiple brands. So far Mobil 1 brand exceeds all of expectations. You can see a big difference in performance when using Mobil 1 motor oil. The engine definately runs smoother. Oil changes are never a problem with this oil. I definitely recommend Mobil 1 oil. It truly stays on top of all the other oils.

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 noticed the difference between Mobil1 and other synthetic since the first time i use it on my 2013 Sonic, and now has 56k miles on the clock. The engine turn to be more smooth and quiet. I realize that this is the only oil that i trust. There might be other good full synthetic but i dont want to risk it, for me Mobil1 has proved it all the way.

proof is in the miles. my2003Ford Ranger4.0 just turned 174,500plus miles with this oil. used wix filters until high mileage mobil 1 filter became readily available 125, 000 miles were in dallas , tx traffic and hot texas weather,balance in Missouri weather since retiring. still no oil consumption or leaks, gives me20- 22 mpg, 5spd, 4x4 with 4.10 gears. use same oil in my john Deere 445 lawn tractor, john deere4x6 gator, new scaggs turf tiger zero turn mower and new ford f150 4x4 eco boost 3.5 whichjust turned 35,000 miles, with no consumption, As a side note, use 5W40 mobil1 in my 65 hp john deere turbo diesel 5320 tractor, just turned over1000 hrs.with no oil consumption. my wife's Toyota Avalon 2014, run 0W20 mobil1 with mobil1 filter, change oil once a year, usually just a bit over 10,000 miles. does not us a drop of oil, currently at 50,000 plus, will change after bad weather is out of here , southwest missouri . current oil still looks clean on dip stick. gave us 35mgp round trip to Dallas, tx, over thanksgiving nearly 900 miles on the road. why use any other oil, as is readily available even in rural Missouri.

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

I have to say I finally wanted to change oil to Mobil 1 for awhile and I’m glad I did. Without getting into statics about my 2017Camaro this motor oil made my V6 run ever so smooth and quiet! I went on a long trip purposely and did spirited driving and even got stuck in traffic without any loss from burn off. I switched from Valvoline synthetic and noticed a difference within 200 miles. I really thought it was just my imagination at first but yep there is a difference. BIG DIFFERENCE! If you want the best protection I recommend this oil for your ride.

[This review was collected as part of a promotion.] Great oil for whatever you're running. The Full Synth formula is long lasting giving you ample protection. Having just replaced my Mobil with this Mobil, I can say it last the last 5 months with no issue, oil is black but still has the hint of gold your looking for to make sure its not getting to dirty or burned. Be getting again in the future.

i have used mobil 1 pure synthetic for almost 2 years now in my 2011 chevy hhr and have had no problems ,it has now 74,500 miles on it and doesnt use any oil i dont have to add any between oil changes . i would like to start using the high mileage but it is not dextos approved and after talking with a mobil rep i am going to the extended performance pure synthetic .

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.

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.
