Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Cost a little more, but in the end you'll save! I started using Mobil I oil over 7 years ago. My truck runs smoother and I have had no issues with the engine. Sure it costs more up front; but in the end you'll save ten times over that! This oil will definetky save you from those expensive repairs that are caused from inferior oil. I bought a Toyota Tacoma because of their reputation and reliability. I use Mobil 1 to make sure my Toyota stays that way! I love that I can change my oil every 7,000 to 8,000 miles not 3,000 like standard oils require! This is the only oil I'll ever use. Try it for 6 months and you'll see a difference!

Rated 5 out of 5 by from Very few are true synthetic ! 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

Rated 5 out of 5 by from Best for performance I run this in a 2011 Mustang GT that I'm just starting to mod. I have done my rounds with Castrol Edge and Valvoline Synpower in the past and they don't hold up as long and perform as well as Mobil 1 extended performance (and yes I even used Castrol edge extended performance). IMO it is due to Mobil 1s superior synthetic base stock used in it. ExxonMobil is not ashamed or trying to hide their base stock info. You can get it off their website !! Bottom line is when I fall asleep at night j feel better knowing that I have Mobil 1 in my engine to combat the higher engine temps and sludge prevention.

Rated 5 out of 5 by from Reliability & Performance I have been using Mobile 1 Extended Performance 0W-20 oil since Day One. After 286k miles our 2009 Hyundai Sonata runs like the day it was new. I change oil and filter every 6-7k miles. The engine runs so silently I often turn the key to start by accident when the car is running. There are no leaks, although we do add a half quart between changes sometimes. Maybe someday we'll switch to Mobil 1 High Mileage but certainly not until something changes. I cannot recommend this product highly enough!

Rated 5 out of 5 by from Highest Percentage of Group IV PAO Don't know what a group IV PAO is? Google "Group IV synthetic motor oils". Check out the SDS (Safety Data Sheet) from Mobil on this product and you'll see it's ONLY the 0W-20 Extended Performance (Not the Advanced Fuel Economy) that has 60%-70% of the homopolymer 1-decane. The same product line, Mobil 1 Extended Performance 5W-20 doesn't come close to this high percentage of Group IV PAO. Why does this matter? 1-decane is made as a 10 carbon chain polymer that is truly man made which means a more consistent molecule size/shape running through your engine. Pairs well with the Mobil 1 Extended Performance M1-110A for my newer Hondas. Why 110A versus 110? 110A was redesigned to extend filter life to 20,000 miles from the 110 version which was protection to 15,000 miles.

Rated 5 out of 5 by from Fantastic oil for a high performance turbocharged Everything about the environment and conditions my car sees says the oil is going to have a big job on it`s hands. Ultra hot 100+ degree summers, sub freezing winters, heavy traffic, not to mention the nature of a high performance engine outside of environmental challenges. I changed this oil at 8K miles and the oil analysis came back absolutely perfect, even with 100K miles on the engine and it didn`t burn a single drop between changes. Three decades of high performance involvement and I`ve not seen an oil quite like this. I have 100% faith in it.

Rated 5 out of 5 by from M1 Beats The Assault By Coolant We got another Chevy Express, this time with the V6 and 140,000 miles. Intake gasket dumped coolant in the oil at 168,000 miles, driven about 40 miles, severe chocolate pudding. When you see temp start going up slightly and oil pressure going up at the same time....pull over and check your oil if it's a GM with this design. Changed filter & oil at home, cranked it up and listened to lifters rattle for 3 minutes(full of coolant & oil pudding) until it quieted, drove it to the shop for the gasket fix. Changed oil and filter again after the repair. It now has 247,000+ miles on it and going fine. Thanks M1 !!!
