I use Mobil One synthetic in both of my vehicles. I use the Extended High Mileage in my 1999 Ford Explorer. Doesn’t burn oil and never have had an engine issue. I also use it in my 2014 Hyundai Santa Fe 2.0T. Again, engine doesn’t burn oil and never had an engine issue.

I've been putting nothing but Mobil 1 in my cars after talking to an engine specialist in the Ford SVT group who said that they only run Mobil 1. It has never given me a problem and my 2000 Ford Expedition is coming up on 300K miles. 1 engine - 1 motor oil. Save yourself some money and only use Mobil 1.

My brother who has been a professional mechanic for 25 years, recommends Mobil 1 Extended Performance oil. My dad, who has been an avid Havoline and STP fanatic all our lives, also uses and recommends Mobil 1 Extended Performance. I've been using it in my turbo charged Volvo, my normally aspirated Saturn Sky, and my daughter's Honda Civic for over 2 years, changing the oil and filter at 10 -15,000 mile or 1 year intervals. I am a fanatic about my cars and only want what is best for them. (I was unaware until today that Mobil 1 had filters, so I've been using another premium brand.) The oil is very black which tells me it is doing a good job of keeping my engine clean, and it still runs out thin when draining. Also, after changing the oil, on first start up, there are none of those few seconds of engine clatter waiting for the oil pump to refill and pressurize like there is with conventional oils, indicating that the oil has left a protective film in my engine. I'm impressed. I do have a question; my Saturn Sky (no turbo) has always had lots of valve clatter. It may be normal, I don't know. It currently has 75,000 miles on it and there is no valve adjustment on this engine. Would Mobil 1 High Mileage help with this? It's a high revving engine so I don't want to do the wrong thing.

I own 4 different vehicles of all different types new, old, performance and even an old 1993 Honda Del Sol. I always follow Mobil 1 Oil website recommended viscosity for these vehicles and none of them has given me any issue whatsoever. This will continue to be the only oil that I put in my cars.

Instant Satisfaction! I made the switch to Mobil 1 Synthetic Oil in my 1987 IROC-Z Z-28 Camaro 5.7 Litre w/55kmi. First time out with the new oil & filter, it felt like I was gliding down the the road. It was an amazing difference. Not only was I smiling, my motor was too!

I have used mobile 1 full synthetic extended on all my cars. 250,000 on my 2005 Ford five hundred and going strong. Over 100,000 on the 2012 Chevy Impala and no issues. Don't think I would go to the 15,000 mile mark between changes. More like 5,000 between changes to be on the safe side.

1 have a 165,000 miles on my 2001 Chevy Impala LS with a 3.8L and had to change the oil after 5,100 miles. I used the 5W-30 Mobil 1 Extended Performance oil with the M1-101 Mobil 1 extended performance filter. I understand oil filters are not designed to filter oil up to 15,000 miles even the Mobil 1 Extended Performance filter. The oil claims to protect up to 15,000 miles which I would never use oil up to that extent. I however I was hoping to get at least 8,000-10,000 miles out of one oil change. The oil got black after the 5,000 mile mark. My engine is in 100% working condition and have not had any serious engine issues, but rather the typical fixes of head gaskets and ect due to age. Also I use to change my oil every 3 months even if it didn't reach the mark of 3,000 miles with regular 5W-30 oil. Overall I rate this oil as a 2* being it was not able to reach at least 8,000 miles on one change for a "Full Synthetic Oil".

I use to change my oil every 3,000 miles with pennzoil.But now that I am retired the last 8 years. I only drive 2,600 to 2,800 miles a year. For the last 3 years,I have changed my oil every late march,or early april with mobil one e.p. 5w-30 and mobil one filter. No problem with my 1999 ford tarsus s/e vulcan,128,000 miles. This will prbly be the last car,I will ever need,and Mobil One,will be one of the reasons.

I have used Mobil 1 for as long as I can remember and never had a problem with any of my cars or trucks. The first time I used Mobil 1 I noticed the engine ran a bit cooler and the gas mileage improved. I also use Mobil 1 Oil Filters and Mobil 1 Grease. I change the oil between 7000 & 8000 miles and the oil comes out of the engine almost as clean as it went in the engine. I know this because I change it myself. A Friend of mine had a 1995 Ford Thunderbird with over a 100.000 miles and the oil was always black as coal. I told him I would change oil 4 times in a row for him using Mobil 1 10W-30 and if the oil did not start getting clean he would not owe me a dime for the work or the oil. He agreed and after the fourth oil change We could barely see the oil on the dip stick. Well in the end he was happy and I got paid. The only sad part about this story is shortly after we did the experiment he was rear ended on an exit ramp and the car was totaled and thankfully no one was hurt. But too this day Mobil 1 Oil and Mobil Oil Filters are the only products he will put in his cars. P.S. Mobil 1 Oil is the best cold weather oil that I ever used! Thank"s For Taking The Time Too Read My Review, Pat Regan Throop Pa.

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.
