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 ma…

You can’t undo the flush. About all you can do is make sure all the flushing chemicals are now out of the motor to reduce potential damage. To me that means another oil change perhaps in a few days and a few hundred miles. Take that TSB to the oil change place and negotiate for another oil change…

Wallet flush…doesn’t help, never seen any damage as a result. Hot mineral oil usually, you could see whats in GUMOUT but probably not harmfull. The TSB I heard was a result of improper procedure in the flushing (they ran the motor)

I’d 1) find a good independent shop to do your oil changes, no chains, then 2) get it changed in a week or two. I would not worry about it.

" find a good independent shop to do your oil changes, no chains" I’d take a different approach. Find a good shop to do your work in the future, or do it yourself. It doesn’t mater if it is a chain or not, but that it is a good place to get work done. I use a chain place to get oil changes and t…

Thanks everyone for the answers. I am going to drive it to/from work until about Thursday. That will put around 160 miles on it. Then I will have oil changed again (different place). I have also sent a letter and the TSB to the place that did the flush. I don’t expect much from them. But I di…

“Good history of oil changes.” I doubt there was any sludge or residue for the flush to remove.

Those oil change places are the “jump off the Empire State Building” of the new Baloneyum. People keep trusting them for some reason. Don’t worry, they probably faked the job anyway. There’s this place that wants me to buy an additive for my synthetic oil change. Unbelievable.

One point not yet made: don;t beat yourself up over this. It’s extremely easy for a shop guy with a company patch on his coveralls to convince the average person to have things done that do not need to be done, and vene to do things that should not be done. Those that do so are experts at it. I’ll …

Last year I went to the dealership to get the engine computer replaced on a recall. I opted to have them do it while I wait. It shouldn’t take long to unplug a little box and plug in another. Plus, I wanted to be there in case there were any issues. I was there about 2 hours because the first rep…

The oil change place is out for $$$$ pure and simple. Your motor fails two days from now, prove it was them they dare you. In any event I highly doubt you did any damage to the truck, the tsb is most likley an extream.
