Bought Ford Escape 4cyl and Chevy Silverado 6.2 liter V8 new in 2012. Mobil One Extended Life used in both since day purchased. Presently Chevy 148,012 miles and Ford 141,310 miles. NO leaks, No use of oil between 6,000 mile oil changes, No problems of any kind. I am retired now and expect to get 200K to 300K from these two thanks to Mobil One and simple maintenance. I always use Mobil One filters at every oil change. C. Linton

I have been using Mobil 1 synthetic oil for over 10 years in all my and my son's vehicles. None of them have had any mechanical motor issues in all that time. Prior to using Mobil 1 I had 3 vehicles have major mechanical engine issues. I am not a mechanic but am mechanically inclined and am convinced this is some excellent oil.

Everything about the environment and conditions my car sees says the oil is going to have a big job on it`s hands. Ultra hot 100+ degree summers, sub freezing winters, heavy traffic, not to mention the nature of a high performance engine outside of environmental challenges. I changed this oil at 8K miles and the oil analysis came back absolutely perfect, even with 100K miles on the engine and it didn`t burn a single drop between changes. Three decades of high performance involvement and I`ve not seen an oil quite like this. I have 100% faith in it.

Using currently in my 2017 Nissan Titan. So far changed twice at 15k. Oil looked VERY close to new both times. NOT dark at all. I am a used car dealer.... I know what dirty oil looks like. My truck was towing a heavy RV trailer (7500 LBS) about 3rd of time. Also I bumped up viscosity to 5w30 Not a big fan of CAFE guidelines telling me what's better for MPG. I almost went 10w30. I have been pairing this with "Purolator" BOSS oil filter. and feel very confident about this oil for my truck. Love the 15k interval and the feeling you have the "BEST" oil on the market in your truck. Will continue to use. Little pricey yes. But saves with the interval.

I've used Molibe 1 in my engine ever since I bought it. I just passed 427,000 miles and it still runs fantastic. This is my work vehical. I do not baby it, but don't abuse it. I trust it completely even with the miles on it. It has never been rebuilt or opened up for internal egine problems. I only trust Mobile 1 to keep it doing exactly what it's doing! As far as I'm concerned, there is no other motor oil, all 4 of my daughters, all my friends, and anyone who asks me, all get the same answer, put Mobile 1 in your engine, and never worry about your engine again. I will let you know how things are going after half a million.

I usually use amsoil products but couldn't get it this time and was already past due on this service. So I figured I would try mobile one. Bought the 20,000 mile 5 quart jug of oil and the matching 20,000 mile filter. Performed the oil change and filled it up with oil. I poured In 4.5 gallons of your 5 quart jug and my car was still way low. Finished pouring in the rest and it was still low!!!!!! The car is a Nissan rogue with a 2.4 liter 4 cylinder engine that only holds 4.8 quarts of oil!!!!!!!!!!!!!!! I have owned this car for 3 years and this sure isn't my first oil change on this car or in my life. Been a professional mechanic for 23 years. Had to go a buy a couple more quarts of your oil. What's up with that. Probably wont use your products again after this. Unless you feel the need to make it right which I am highly doubtful you will.

This oil is extremely well rounded and worth the extra cost over almost all other synthetics. It is a fair deal at Walmart for 28.68$ / 5qt jug however, I wouldn't pay 10$ a quart for it at the local auto parts store. I have a 2012 Genesis Coupe 2.0T with 141,000 miles on it and counting. I have used this oil for the majority of oil changes, all of which I have performed myself. I live in northern ND and this vehicle faces extreme cold conditions for a quarter of the year. I have never run into any engine related problems the entire time I have owned this vehicle (bought it new#. I would never run this oil for 15,000 mile intervals being that it is a turbo engine however I have pushed it as far as 6400 miles with no problems. I have always been a loyal BP fuel customer and, as a result, have tried to convince myself to switch from this oil to Castrol Edge Extended Performance especially since Walmart now carries it in 5qt jugs for the same price. After a couple Castrol oil changes I have switched back to Mobil1. Although the Castrol held up fine, I can't help but feel like it is an inferior product to Mobil. After 5800 miles the Castrol poured out extremely thick and I do notice better fuel economy with Mobil1. I drive a lot and constantly monitor wind, temp, etc. and take this into account with fuel economy. I believe there is a good reason why Extended Performance Mobil is consistently selling out at both Walmarts around here. If your going to spend this much on an oil change, I would strongly suggest using this Mobil 1 Extended Performance oil and also a quality oil filter #Not a Fram, etc.) There is no point in using oil of this caliber with a 3-4 dollar filter. My only complaint about this product is the price of Mobil 1 E.P. oil has gone up significantly in the last year, I believe in early 2014, I could buy it for $25.17, then it went up around April/May to $27.97 and now, $28.68. If it goes up another $3.50 next year I will most likely consider something different. As comforting as it is to know I am using a product that will tolerate anything I would possibly put it through and then some, there are many other oils less expensive that can sufficiently protect my engine too. In the end, I recommend this product to anyone looking for a top notch oil. It is worth the extra 2$ investment over regular Mobil1 in my opinion and based on the research I have done online. If you are looking for a quality synthetic at Walmart, you will find most everything has a similar price. I would strongly advise choosing this motor oil over Pennzoil, Castrol, etc. based on my experience.

I have used Mobil extended for at least 15 years in different cars,trucks and never had a problem

i have been using mobil 1 oil for the past 10 years

excellent product i have been using it last 20 years
