15,000 miles of protection for high mileage vehicles – guaranteed*

*Please follow the recommendations in your owner's manual while your car is under warranty.

Discover Mobil 1 Extended Performance High Mileage, the only high mileage motor oils to guarantee 15,000 miles of protection between oil changes. These advanced full synthetic motor oils are designed to protect critical engine parts for 15,000 miles between oil changes and help extend the life of vehicles with more than 75,000 miles – guaranteed.*

Available in 0W-20, 5W-20 and 5W-30 viscosities, Mobil 1 Extended Performance High Mileage oils are recommended for all types of modern vehicles, including high-performance, turbocharged, supercharged, multi-valve and fuel-injected engines that are found in passenger cars, SUVs, light vans and trucks.

If your engine contains excessive sludge deposits due to less-than-adequate maintenance practices, Mobil 1 Extended Performance High Mileage synthetic motor oils can help reduce this sludge. For severe cases of engine sludge, short oil change intervals (3,000-5,000 miles) are recommended for the first two or three oil changes as the sludge reduction takes place. (In cases of engine damage that may have resulted from poor maintenance, even Mobil 1™ motor oils cannot remedy years of neglect.)

Please reference our Mobil 1™ Product Guide for a quick look at specifications including zinc and phosphorus, as well as manufacturer approvals for Mobil 1 motor oils.

We stand behind our products. Read our Mobil 1 Extended Performance limited warranty.

We recommend using Mobil 1™ Extended Performance oil filters with Mobil 1 Extended Performance High Mileage synthetic oils. Though not required, these filters meet the requirements of the Mobil 1™ Extended Performance High Mileage limited warranty and are perfect companion products for longer-lasting protection.

*Please follow the recommendations in your owner's manual while your car is under warranty.

Rated 5 out of 5 by from What a difference my warranty is looong gone. this is for a 2003 nissan 350z.. i was using regular oil..it was running fine..but when i bought this car, the seller told me that it runs fine on regular gas... nope..valves were clicking as heck under load.. so i checked out the 'net and the online specs on these cars.. it says to use premium gas so i did that.. it got most of the valve noise when accelerating.. but it was still there .. not as much.. so i decided to switch to this oil...car have over 125 000 miles.. now..it purrs like a kitten and accelerates how it should.. no strange noise..just a great exhaust sound .. thanks Mobil 1..

Rated 5 out of 5 by from Extended oil change interval in 2011 Camaro V-6 Used it in a 2011 Camaro with a V-6 and 97,000 miles. Changed it at 12,240 miles and had the used oil tested at Blackstone Labs. Wear metals were quite low, matching other oil samples done at just 5,700 miles average. Anti wear ingredients were still higher than average samples. TBN number showed that we could get another 2,000 miles out of this oil. Oil filter was changed with the oil and was the Mobil 1 Extended Performance filter for synthetic oils, part number M1C-254A. Car is driven in LA traffic about 2,500 miles per month.

Rated 5 out of 5 by from 298,000 Mileage 1996 Ford Explorer I have used Mobil 1 Full Synthetic and then Mobil 1 Extended Performance in my 1996 Ford Explorer since I got it 4 years ago. The mileage is almost at 300,000 miles! (298,000) and I have had no issues whatsoever with the original 4.0L engine. I have now switched to the New Mobil 1 Extended Performance High Mileage formula since it adds a preventative stop leak for the seals. You cannot beat Mobil 1's Full Synthetic Oil for superb protection of your valuable engine.
