SERVICE INFORMATION

The supplemental information below should be used when following the On-Car MPFI Injector Cleaning Procedure outlined in Dealer Technical Bulletin 85-T-47.

After the injectors are cleaned, owners should be advised that use of fuels with detergent additives should keep the injectors clean. Premium unleaded gasolines generally contain lower levels of materials believed to form deposits, and higher levels of detergents than regular unleaded gasolines.

Their occasional use could help prevent future injector deposit formation. There are encouraging signs that oil companies are addressing deposit formation and will be providing regular and premium unleaded gasolines with higher levels of detergents which can prevent, and in some cases, even remove injector deposits. This will be a welcome development not only for Oldsmobile owners, but also for owners of other domestic and foreign cars equipped with port fuel injection systems. Local gasoline advertising is one guideline for selecting fuels with high detergent content.
