Your diesel fuel has problems nobody talks about...

Modern diesel came with a cost - less natural protection for the parts that matter most.

What changed?

Modern Diesel has 3 Problems.

Your fuel system pays for all of them.

LUBRICITY

Dry fuel. Expensive wear.

Ultra-low sulfur diesel removed natural lubricity, increasing friction and heat in high-pressure components.

You'll notice:

  • Accelerated pump & injector wear

  • Noiser engine

  • Rougher idle

DETERGENTS

Dirty injectors. Poor performance.

Diesel fuel from the pump doesn't keep injectors clean enough to maintain the spray pattern your engine was built for.

You'll notice:

  • Poor throttle response

  • Degraded fuel economy (MPG)

  • Smoke and increased DPF regen frequency

LOW CETANE

Incomplete combustion. Lost power.

Lower cetane means a poor burn and dirty injectors, pushing extra soot and carbon into the turbo and DPF.

You'll notice:

  • Harder starts

  • More frequent DPF regens

  • Higher soot output

Engineered for Modern Diesel.

Modern fuel is drier, dirtier and slower to ignite. Archoil is built to correct that at the pump.

Put Protection Back in the Fuel

Our diesel treatments improve lubricity to reduce friction and prevent premature failure.

Cleaner Injectors. Optimal Performance

Remove and prevent deposits that reduce power, throttle response and fuel economy.

Reduce Deposits and DPF Regens

Cleaner and more complete combustion means less soot loading in the post-combustion system.

The Diesel Fix

Protect. Clean. Boost.
