[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’ve run only Mobil 1 full synthetic for the last 15 years in cars ranging from an 03 Mercury Marauder to the current build on a modified 96 Volvo 850R. I usually run about 5000 miles between changes. The inside of my engines have no sludge build up and the oil looks like clear honey on the way out.

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!

My 03 Camry with 2.4L topped 360000 miles this week engine gets the same milage as it did new. The car uses no oil between changes and when I replaced the cam cover gasket the engine was spotless inside. I have used the 5w-30 since the car reached 5000 miles.

I have used Mobil 1 for over 10 years on my 2008 Honda Civic. The vehicle now has over 340,000 miles! I have tried a few oils during that time frame, and I always come back to Mobil 1. For most of the car’s life it has used Mobil 1. After using Mobil 1, the engine seems more responsive. The Mobil 1 filter also ensures peace of mind, as you can extend your oil change interval. I usually change my oil every 5,000 miles. I would be highly interested in doing a commercial for Mobil 1 once my car hits 600,000 miles!!!! Thank you Mobil 1!

I've used this product for 150,000 miles in my Acura TL, the car presently has 235,000 miles on the odometer. I pour the old oil back into the bottle and it fills it right back up to the top. The car doesn't use any oil over the 7,500 mile oil change interval. I use it in lawnmowers, snowblowers, generators, never had an oil related failure. Once I drained this oil out of my lawn mower and forgot to refill it, the engine ran for 5 min with no oil in it. The aluminum connecting rod seized to the crank but no damage to the rings. That's good oil.

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 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

My 2007 Corvette with 60,000 miles maintains 28 psi at 70 mph 1750 rpm, oil temperature of 220 degrees. This hasn't changed since I've owned it for two years, considering changing to a higher weight or different oil manufacturer. Cold oil pressure can climb to 80 psi, when hot pressure falls off rapidly. Mobile 1 suggested to keep using 5-30, or maybe 0-30, but not 0-40. Why? I feel my oil concerns are due to thermal breakdown. The only way to increase oil pressure when hot is to use a higher weight oil, or a better grade oil that resist the effects of heat. Just my 2 cents worth...

Mobil 1 Full Synthetic 5W20 until 75,000 miles then Mobil 1 Full Synthetic 5W30. My wife's 2016 KIA SOUL would crank and run with no issues right up until someone hit her from behind on the Interstate and totaled her car. She was going about 55 mph and they were going at least 80 to 100 mph. The care was folded under, but the engine was running like normal while the Highway Patrol had to pry her out of the car and the Tow Truck guy had to open the hood and disable it to get the engine to stop running. My wife suffered no injuries. We went and purchased a new KIA SPORTAGE and are using Mobil 1 Full Synthetic Oil in it. Who ever buys that car for the engine is getting a solid KIA SOUL engine. At 200,000 miles we started using Mobil 1 Full Synthetic 20,000 mile oil. That Soul would crank and start like a new car. We have a 2001 Ford F-250 V-10 Triton Crew Cab and 2002 Ford F-250 5.4L Crew Cab 4X4 and they both are above 200,000 miles and we run Mobil 1 Full Synthetic 20,000 mile oil in them.
