ENGINE OIL PRESSURE GAGE READ REVISION TO OWNER'S MANUAL

VEHICLES AFFECTED: 1982-84 'J' Series Vehicles

The engine oil pressure data published in the 1982, 1983 and early editions of the 1984 'J' Series Owner's Manual was incorrect. The second printing of the 1984 'J' Series Owner's Manual will be revised to show 50 to 60 psi (approximately 343 to 413 kPa) at road speeds of 56 to 64 kph (35 to 40 mph).

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
