Feeling Like Your MPG and Power Might Be Down?

If your diesel feels down on power, seems louder than normal, smokes more than usual, or has lost fuel economy, fuel system deposits may be part of the problem. They are not the only possible cause, but they are common enough to be worth considering.

Why Deposits Matter

Modern diesel injectors operate at very high pressures and use very small openings to atomize fuel. When deposits form on injector tips or inside the injector, the spray pattern can be affected. That can lead to rougher running, more smoke, reduced responsiveness, and less efficient combustion.

Where Single Clean Fits

Opti-Lube Single Clean is designed as a stronger one-tank cleaning treatment. It can be used when injector deposits, smoke, rough running, or fuel system cleanliness are the main concern. After that cleaning treatment, most customers return to a regular maintenance additive such as XPD All-Season, XL Extreme Lubricant, or Summer+.

When an Additive May Not Fix It

If the issue is caused by a mechanical problem, boost leak, air restriction, bad sensor, tuning issue, emissions-system problem, or worn component, an additive will not correct the root cause. In those cases, diagnosis and repair may be needed.
