BG Diesel Engine Performance Service

Diesel DOC

Why Diesel Owners Need This Engine Service

Diesel engines often experience compression loss due to deposits that impede piston ring function.

The result is excessive blow-by, which leads to decreased power output and poor fuel economy.

This is BG’s best engine oil service for diesels. When your diesel customers get this service, they can expect an even longer life span of their powerful, fuel-efficient diesel.

How to Perform a BG Diesel Engine Performance Service

BG EPR Engine Performance Restoration is added to the diesel crankcase and circulated. Deposits are dissolved and suspended in the old oil, which is then drained.

BG DOC Diesel Oil Conditioner is added to the clean oil in the crankcase to maintain oil performance during extremes of diesel engine operation.

Once the oil change is complete, BG Diesel Fuel System Performance Restoration is added to the fuel tank to circulate and clean the entire diesel fuel system, keeping it running smoothly and efficiently.
