Been running Mobil 1 for many years in everything from pickups to snowblowers to motorcycles! Keeps your engine very clean and cool. Not high priced like some of the so called premium oils. This is a premium oil!

Ran this in my last truck religously for over 9 years and 240,000 miles. Got good fuel mileage, great performance, and never had a single problem. Needless to say I'm continuing that with my current truck and having the same results.

How does one really know how the oil that they use is really good oil? Well, all i can say is that with using Mobil 1 for quite some time now, I've never had any motor malfunctions. Change it on schedule and use Mobil 1 and you're good to go.

I've been using Mobil1 in my vehicles and mobile equipment for over 15 years. 3k mile changes are just sales techniques. New cars can go 8k or more without needing a change. I have run 300k on a couple cars. I trust Mobil1.

I've been using Mobil 1 Synthetic for well over 10years. One oil change a year or 10k miles makes the life much easier, and all my cars run excellent - and this includes 3k miles Acura *practically new) or 90k G37...

The only oil I use. Dozens of cars over the years and not a single oil-related breakdown. Also great for small engines like snowblowers and garden tractors!

Most amazing oil. I have used these in my fleet of minivans for over 15 years now. I noticed the EP (Extended Performance) version went from a guarantee of 15k miles to 20k now. I do push the limits on oil changes and have gone over 15k many times. Some of my vehicles have over 200k miles. They all run perfectly. A good check of how much protection your oil has after 15k miles is to rub it between your fingertips and if the tips have some resistance you can feel that it is still protecting. The viscosity is the key to knowing if your oils needs to be changed. If you rub your fingers together and it is not slippery feeling the oil is not doing much.

I've been using Mobil1 synthetic oils for over 20 years. The engines out last the car bodies. Never have had any internal engine problems. If anyone swaps from another oil and you do your own oil changes, be warned that you oil is going to come out as black as coal. It will be like that for 2 o 3 mobil 1 oil changes, 3 new truck I had dealer change oil 2 times on each because it was free service. All 3 trucks took a couple oil changes before it got all the sludge and dirt out. Running 10k miles between oil changes. After 2-3 mobil changes the oil starts coming out the color of dark honey.

I always use Mobil 1 synthetic for all my cars and so does my family. Great product, never had any issues.

Product works well. Haven’t tried the extended life part as need to change at lesser interval to stay under warranty.
