    STRONG OIL FOR HARD WORKING ENGINES!

    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.

    0W30 ESP X2 to 5W30 Extended Performance

    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

    Viscosity is the key

    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.
