Have been running 5W30 Extended Wear in a Supercharged 1998 4Runner since 2004. I have enough confidence in it, to switch two newer VW's that call for VW 508 (ESPX2 0W20), to Extended Wear 5W30. Extended Wear 5W30 meets the ESP X2 0-W20 specifications for API SL, API SN, API SP, and API SQ Easy decision

I have been a loyal Mobil 1 customer for more than 30 years. During that time, I have used Mobil 1 synthetic motor oils in every personal vehicle my family and I have owned because I have consistently found the quality and performance to be second to none. Throughout my 25+ years managing the fleet for a Sheriff's Office, I introduced Mobil 1 products into our fleet maintenance program. Since taking over a smaller Sheriff's Office, I have personally performed every oil change on every agency vehicle using only Mobil 1 Extended Performance motor oil and Mobil 1 oil filters. I continue to choose Mobil 1 because I believe it provides the best protection and reliability for vehicles that operate under demanding conditions. Beyond my own agency, I regularly recommend Mobil 1 to other law enforcement fleet managers and agencies whenever the opportunity arises. I genuinely believe Mobil 1 is the ideal choice for law enforcement fleets nationwide, and I enjoy sharing my firsthand experience with others in the profession. I would welcome the opportunity to speak with someone at Mobil 1 about ways I could help promote Mobil 1 within the law enforcement community. Whether through sharing fleet experience, providing feedback, participating in case studies, or supporting outreach efforts, I would be honored to contribute. Thank you for producing products that I have trusted for decades. I look forward to the opportunity to connect with your team and discuss how we might work together to expand Mobil 1's presence within law enforcement agencies across the country.

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.

Used in my 2011 Silverado Chev truck since new.Last year I started using in my 1968 Buick Skylark Car.I bought the car new in 1967 I was 18 years old.This was the first time I put Synthetic oil in my old car.

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.

Mobil has a vested intrest to not over promise.Its in my intrest pay more because i dont want oil related repairs .I wonder if the drain interval will just get you thru the vehicle warrenty? . What would be a drain inrerval that yeilds 300k protection ?

We have 260k miles on our 2004 Corvette and have always used Mobile 1. I'm at the point where I change the oil when the oil life monitor is between 0%-5%. I was able to do this by doing oil samples and when one would come back saying there are still additives in it and I can go longer before a change. I've gone as long as 10k miles between changes. That saves me money and the car is still protected.

I bought a z51 c7 museum delivery first year & still have the car. Dry sump di motor, GM says use Mobil1 & that's all It's ever had. I change the oil once per year myself, engine still consumes no oil 9 years 78k mi later. Engine runs like new, 4cyl mode & all. 32 mpg at 70 mph. GM was right, Mobil1 5w-30. Thank you & Don't change a thing guys.

Mobil 1 is my go to motor oil for many years. This particular viscosity is used in a turbo 4cyl. AWD car and provides 10k miles of use before the oil change. Depending on time of year and conditions I don't always go past 7500 but I feel comfortable going to 10k if needed.

I have been using Mobil oil since the early 80’s love the product the only think I noticed with the extended brand it starts to turn a darker than normal color after about 1500 miles. I pair it up with Mobil extended filter as well. The most I run it for is 8000 miles and never the limit.
