Just today I got snookered (I found out later – I feel so dumb) into getting an Engine Flush on my 2002 Silverado. Good history of oil changes.
The $50 I can chalk up to experience. Not worried about that. What I AM worried about is that apparently I may have permanently damaged my engine and may be looking at a catastrophic failure from oil starvation in the near future (from the horror stories I read).
GM Technical Service Bulletin 04-06-01-029E even addressed this in April 2010.
From that bulletin:
2011 and Prior GM Passenger Cars and Trucks (including Saturn)…
Engine Crankcase Flushing
General Motors Corporation does not endorse or recommend engine crankcase flushing for any of its gasoline engines. Analysis of some of the aftermarket materials used for crankcase flushing indicate incompatibility with GM engine components and the potential for damage to some engine seals and bearings.
Damage to engine components resulting from crankcase flushing IS NOT COVERED under the terms of the New Vehicle Warranty.
Now that is pretty scary.
I just had the flush done today (they used Gumout engine flush). Is there anything I can do now to prevent damage to engine seals and bearings or reduce the possibility of damage? Or is it too late and any damage is already done?
I really feel dumb. I have taken such good care of my truck. Changed the oil regularly and have only 88K miles on a 2002.
But with the release of that TSB from GM almost two years ago now, it seems to me it is downright negligent on the part of the oil change place to push that service, isn’t it?
Anyway, any help/advice would be greatly appreciated.
