Deposit control additives help restore lost power and performance by cleaning deposits from injectors and filters. Regular use prevents future deposit buildup that can cause power loss, poor idle and hesitation.

All our diesel contains additives that help improve combustion for easy start-up and smooth operation.

Clean fuel injectors provide precise fuel flow and an optimal spray pattern that creates efficient fuel combustion. Regular use of Kirkland Signature™ Diesel helps restore lost fuel economy.

Deposit removal allows the engine's sophisticated emissions control systems to work as designed, helping to reduce emissions caused by engine deposits.

Deposit control additives clean up existing deposits and keep new ones from forming. This helps increase vehicle reliability, reduces costly maintenance, and helps restore new engine performance.

All of our diesel contains additives that help protect critical fuel system components from friction and wear.
