WHEN DEPOSITS BUILD UP, YOU SLOW DOWN.

Carbon deposits are a natural byproduct of the fuel burning process. They can build up on your engine’s intake valves, on the piston rings and in the combustion chamber – robbing your engine of performance.

More deposits.
More problems.

If left untreated, deposits can cause a number of other problems. They can increase emissions, causing your car to fail state inspections. They can also absorb fuel, decreasing fuel mileage.
