Mobil 1 Extended Performance is a full synthetic 0W-20 motor oil built for long drain intervals, rated to protect for up to 25,000 miles or one year, whichever comes first. It meets ILSAC GF-7 and adds oxidation control, pre-ignition and timing chain wear protection, and strong cold-start behavior. That long-interval claim is the main edge over standard full synthetics like Mobil 1 Advanced Fuel Economy or conventional-blend oils, which are typically rated for shorter changes. It suits drivers who rack up highway miles and want fewer oil changes, not engines that burn oil or cars still under a warranty with a shorter required interval.

Owners rate it highly, with most praise for smooth running, easy cold starts and confidence in the long change interval. A minority question whether the 25,000-mile claim is realistic for their driving.
