    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".

    Group IV (4) base oil (synthetics) are chemically made from uniform molecules with no paraffin and generally don't need Viscosity Additives. However, in recent years Group III (3) based oils have been labeled "synthetic" through a legal loophole. These are petroleum based Group II (2) oils that have had the sulfur refined out making them more pure and longer lasting. Group III (3) "synthetic" motor oils must employ Viscosity Additives being petroleum based. As more and more large oil companies switched their "synthetic" motor oils to the less expensive/more profitable Group III (3) base stocks and of the large oil companies, only Mobil 1 Extended Performance, is still a PAO based true synthetic

    My last vehicle was a 2000 Ford F-150 with the 5.4 engine . From the first oil change a I always used Mobil one , it had 256.000 miles on her and was still running strong , when I traded her for new F -150 . I will continue to use the best synthetic oil available Mobil one . Thanks for such a great product .

    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.

    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.
