Mobil 1 can clean up virtually all sludge
in just one oil change.
Everyday stop-and-go driving is a major cause of sludge buildup in engines. Mobil 1 keeps engines running like new by providing superior protection against sludge and deposit formation.

Sludge ratings, based on a 10-point scale with 10 being the cleanest, demonstrate the exceptional cleaning power of Mobil 1 synthetic oil.
In a controlled test, a 2009 Chrysler Sebring ran with conventional oil until the engine had formed significant sludge. Technicians then changed the oil, using Mobil 1 5W-30, and ran the vehicle for another 4,000 miles. After that one oil change, virtually all sludge had been cleaned up.
At very high temperatures, conventional and semi-synthetic motor oils start to oxidize and turn to sludge. Mobil 1 motor oils do not. Mobil 1 synthetic oils are capable of protecting engines at temperatures in excess of 500°F/260°C. This type of stability is especially important for stop-and-go driving, for high-tech engines that tend to run at higher temperatures, and for turbocharged engines.

We put Mobil 1 to the test in some of the harshest conditions such as the grueling conditions of Las Vegas. To validate the protection offered by Mobil 1 Extended Performance, we use Las Vegas taxis and push their engines, only changing the oil every 15,000 miles. See the results now.
