Rated 5 out of 5 by Recommended by my very picky family. 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.

Rated 5 out of 5 by 20,000 miles between oil changes 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. January 29, 2016
Rated 5 out of 5 by 302K and Still Ran Like New From first oil change to the last I used Mobil 1 in a Ford Escort from 1993 till 2005 while we racked up over 300K on it. I did the oil changes myself to ensure that only Mobil 1 would be used. The engine never displayed any lubrication issues whatsoever during my ownership of the car. That's right. No oil burning, no crank seal leaks and no perceptible increase in valve train sounds. Please allow me to digress a little further. My decision to go with Mobil 1 back then was based on an old Air Force study, published in 1978, holding that even with drain intervals increased to 25K (!) Mobil 1 prevented lubrication issues in the dump truck engines used for the study. Based on the information above I started using this extended product last year in our Ford Focus and have since put 13.2k on it with no issues at this this time. I will change it shortly. I think it fair to say that we can entrust our engine lubrication to this product. January 1, 2016
Rated 2 out of 5 by Did not last longer than 5,500 miles. 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". December 22, 2015
Rated 5 out of 5 by 250,000 miles and going strong on my Ford. 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. November 28, 2015
Rated 5 out of 5 by If only the world was as great as Mobil 1 ! Vehicle: 1997 Pontiac Trans Am WS6 - 5.7 Liter - 6 Speed Be it summer or winter, Mobil 1 Extended Performance (in my case: 5W-30) has never let me down. Protection to 15,000 miles is extraordinary. And at 4,000 miles, the oil still looks very clean. A proven attribute to the Mobil 1 (M1-111) Extended Performance oil filter. (and K&N air filter) A match made in heaven. Despite my confidence in this oil going the 15,000 miles distance, I choose to drain and refill with new Mobil 1 Ext. Performance along with a new Mobil 1 Ex Perf. oil filter at 3,500 to 4,000 miles. I just feel better about this... you know... the "peace of mind" thing. I can't help but wonder what other astounding oil and fuel breakthroughs await us car & truck lovers from Exxon-Mobil in the future. Thanks. November 7, 2015
Rated 1 out of 5 by Engine burned 6 quarts in 3000 miles Used this oil in Nissan pickup engine with 3,000 miles on this oil, engine was loud with valve train noise and oil got low everyday, burned up 6 quarts of oil in a rebuilt ka24e that is broken in by dealership, spent 40$ for mobil 1 & top offs which is is 40$, so my expense is high, i switched to Valvoline and don't recommend this on vintage Nissan's.

Rated 5 out of 5 by Amazing product #5W-30 EP I live in Montreal, QC, Canada. We see more then 5 months of extreme cold temps here in this region. Started using this product since Jan 2014 till this date and I see a huge difference in performance of my 2004 Toyota Corolla. After 10000 KM oil change interval, I have witnessed a reletevely clean oil discharge. Engine runs smoother and happier for sure. The only problem is this oil is extremely expensive at Walmart OR Canadian tire here in Canada. A 4.4L jug is usually $59.99 + Taxes which comes to almost $70 CAD. I would strongly convince my wide group of friends and family to switch to MOBIL 1 EP, if there was a reasonable price set out to buy this product. September 15, 2015
