In June 2019 I changed the oil in the gas engine of 2013 Chevy Volt using M1 EP and a M1 filter. The gas engine in the Volt only runs when the battery reaches its minimum state of charge. Most of my driving is within the battery range, and as a result, the engine ran for less than 350 miles in the 2 year period. But the battery life monitor in the car just indicated it is due for a change due to elapsed time, so I am draining the "old" oil that is a clean as new, and refilling with the same product again and a new M1 filter. Since this will probably again be a long interval, I am quite comfortable using the Extended Performance oil and the premium filter to protect an engine that is idle for long periods.

I drive 20,000+ miles a year and started using Mobil 1 at about 115,000. My engine is smoother and quieter than it has ever been. Change oil about every 12,000 miles and it comes out dirty, but no sludge like I used to see. Very happy with the performance and mileage I receive while using this product. My vehicle now has over 186,000 miles on it and moving right along. Why not spend the extra few bucks for a product that you know is the best.

I have been using Mobil 1 since around 1980. I do my own oil changes, and since the Extended Performance came out, I change oil once per year per car (we only put around 10,000 miles per year on our cars), and I change the oil filter at 6 months. One thing I have always done is feel the oil after I change it, by putting some of the drained oil on my fingers and rubbing them together. This oil feels better after 10,000 miles than Standard crude oils do when new. I have never had a mechanical engine failure , ever.

I drive a Nissan Sentra with 260,000 miles on it. I've always used Mobil 1 Extended Performance 5W-30 motor oil. I change my oil every 20,000 miles. I also always use the Mobil 1 extended performance oil filter. At 260,000 miles, my Nissan runs as good as it did when it was new and doesn't use any more oil between oil changes than it did when new. This is by far the best oil I have ever used and will never use anything else. I even use Mobil 1 oil in my riding lawn mower.

I use this oil in my 2008 Lexus GS350 that has over 300,000 miles on it. The cars runs like it is brand new so I am very happy with the product. If you like taking car of your car like I do use this oil and save by not having to buy a new one unless you want

Let me explain by this: I have two cars; one is a 2006 Infiniti G35 that my wife rides and the other is my daily, 98 Buick Lesabre. my wife does not know anything about the cars. I mostly use Pennzoil but this time I preferred that one. My wife drove the car somewhere and when she came back home asked me: did you fix something on the car? It runs very smooth and silent. I will definitely keep using that oil.

I have a 1995 Toyota Camry LE V6. I've used Mobil 1 since day one. About three years ago I switched to Mobil 1 Extended Performance Oil because I started driving longer distances. The oil has held up really well and keeps my engine's moving parts clean. I know because my mechanic changed my head gasket and told me so. I also use Mobil 1 oil filters to match the extended protection of the oil since most oil filters only protect up to 7.500 miles. I love this oil and so does my car.

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 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.

I purchased my '05 Corolla with 18k miles on it in 2007. I've used Mobil 1 Extended Performance 5W-30 since then. My engine still purrs at 258k miles as of March 2018. I have seen a small reduction in performance and fuel mileage in that time frame, but that is to be expected. My engine does not burn oil. I just wish the car would go bad so I can upgrade to something more roomy! Corolla recommended oil change is ever 5k miles. I do the oil changes myself. I change my oil filter every 5-7k miles. I change my oil every 10-16k miles.
