Cannot beat M1 EP or any M1

This oil is truly remarkable. I have been using M1 products in my car ever since the first oil change-- I first used M1 SuperSyn, then M1 FullSyn and now the EP. All them are very good synthetic oils and hold up very well the passage of time. I personally use it on a 2014 Nissan Versa with a manual transmission and a 2011 Impala. The cars don't make any hesitation when turned off and then feel very smooth when driving. No oil loss and the oil is always clean. It is very good on this 110F Texas heat. In fact, I have used other oils that claim to be better than M1 (Balboline, replace B with a V) and I got a seized engine due to poor lubrication. Of course, this does not happen to everyone with that other oil, but it has not happened to me again with M1--and I drive these cars way too hard. Same driving habits I always have. Only complaint with this oil is that the bottle needs a better design in order to be poured easier. Other than that, Mobil, you guys are doing a fantastic job.

How to tell true from false about. Mobil 1™ Extended Performance 5W-30?Can. you. tell. me


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".


Nissan titan

I just changed my valve cover gaskets on my Nissan Titan 185,320 I have used Mobil1 for the last 13 years if you could see the photos under the vale covers o sludge o build up it's amazing still shiny . You can't go wrong . I have owned this truck since new the motor is in perfect condition and so clean inside.


Still protects after 1 year in the engine

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.
