Mobil 1 Keeps Engines Running Clean

Over time, conventional oils can sometimes form sludge, which can reduce your engine’s efficiency and, ultimately, reduce the life of your engine. Mobil 1™ synthetic motor oil contains fewer impurities than conventional oils and is designed to better resist the formation of sludge, thereby maintaining its viscosity (ability to flow) and preventing deposits from forming.

Chrysler Sebring Test

In a test using a 2009 Chrysler Sebring that had significant sludge formation, Mobil 1 synthetic oil cleaned up virtually all engine sludge in just one oil change (4000 miles).

Engine Teardown

In a test using Mobil 1 synthetic oil in a Chevrolet Camaro SS V-8 running at 25,000 mile oil change intervals — 2-3 times longer than recommended by Chevy — there was excellent engine cleanliness and no noticeable engine wear.
