Mobil 1 122598 Synthetic Oil, 6 quart, 1 Pack

This is a 20,000 mile oil - not 5k or 7K like others. Mobil 1 is THE oil used in Formula 1 and other race engines because of it's ability to perform under extreme heat and RPM ranges. As you can tell, I am a BIG FAN. I want my engine to last and I drive in extreme heat conditions in Arizona. It is simply the BEST protection for my engines.I ordered it from Amazon since my local shops so not carry it! [Hell, they get more repeat business if you come for an oil change every 5K miles or so - so a 20,000 mile oil is not what they sell]. It take it to a Jiffy Lube and the installer is amazed when I tell him to set the car odometer service reminder to 20,000 miles. [the shop system he uses to print the windshield ticket doesn't even go that high!]Why do I buy this extended milage oil:- Once a year oil changes- Engine protection in extreme heat [and cold]- Lower viscosity for penetration in all areas of the engineOther companies have their own synthetic oil - but race car drivers use Mobile 1 - what does that tell you?And NO I have NOT been paid for this review - I just love the technology and protection it gives my cars in the heat extremes of Arizona. Be sure to get the extended milage oil filter from Mobile 1 too!

Have used this for the past 4 years and as a person who drives 90 percent highway I am comfortable with the long oil change schedule. I use a Mobil 1 filter designed to go with this oil.

Ever since Mobil 1 annual protection 5W 20W came out I've used it. It is perfect for seniors or people who don't drive much, as this product is good for 1 year or 20,000 miles. Just make sure you purchase the Mobil 1 extended life oil filter as well.
