Added Seafoam in Brake Booster - Wait on Techron ?

[Turk]

Curious...

On a 2003 5.3L GMC Sierra:

I added Seafoam into the brake booster for the 1st time ever in 80k, and noticed a good increase in acceleration response. Man, did it smoke...

Should I wait awhile to add the 20 Gallon treatment of Techron to the fuel...?

If not or if so, why?

Thanks!

I don't see any reason for you to wait. Seafoam seems to be a fast cleaning of the intake and injectors, might as well continue with slower cleaning/deposit prevention with the Techron.

Well, you might seriously consider changing your oil now. The blowby of such a harsh cleaner can contaminate your crankcase oil and knock it's lifespan down a notch.

Titan,

Interesting, haven't heard that before.

I put Amsoil in 3k miles ago - hate to change that out now, but...(?)

Follow-up comments...?

Thanks!!

Never had an issue...did blotter tests and all.

tpitcher, take the car out for a 30-60 minute highway drive, if there were any solvents or chemicals that made it into the crankcase, they should evaporate and go through the combustion chamber via the PCV valve.

I thought an oil change was required if you pour seafoam into the crankcase? Seafoam can be distributed one of three ways...crankcase, gas tank, brake booster...I don't see how the latter two can contaminate the crankcase, no?

Sorry for the newbie-ness

It's blow-by that can be a problem...if your engine was good and warm before you sucked it into the intake via the brake booster...perhaps you didn't get much solvent (or, maybe not any!) past the rings into the oil. Or, if your engine was cold, maybe you did. IF you did it cold, running it hot on the interstate might be just the ticket to burning it all out of the oil...you just don't want it in the oil any longer than necessary.

I put'er in hot.

Then rev'd it up quite a bit right after, followed by a hard run for about 5 miles with lot's of rev's...

Sounds good to me! To be on the safe side, I never do any major fuel cleaning event without changing the oil afterward. It's THE main reason I use Fuel Power 60...doesn't hurt the oil if it gets in there.
