I know everyone is all giddy when they first try it and say they feel all kinds of differences and improvements. But, now that you've had a couple weeks/months to actually notice long term improvements, what have they been (if any)? Any actual degradations from using it? I'm talking anything ranging from better gas mileage, to running smoother, to the car just feeling better in general (mentally). Post 'em up!

(Accidentally first posted this in the internal section, so just use this one instead...)

No notable difference and not much white smoke either. I could have at least darkened the sky with my homemade smog machine but noooooooooo. My kids and I were disappointed at the lack of that positive side effect.

FWIW, I used it in-tank and through the brake booster and at the recommended dosage.

smoother idle and didnt run as rough but I also had 115k miles on stock plugs and all.

Its worth it I mean its only like 6 bucks a can. it cant hurt to clean it out. I got some amsoil deep engine cleaner for the T/A im gonna use when we go to put the GC 0-30w oil in her

i just did it on my '78 Trans Am WS6 and there was VERY SLIGHT change in idle. it idles around 750 RPM and it was just a little bit smoother... other than that, i don't see any noticeable changes. i did the fuel tank and crankcase in my '97 but i have yet to do it thru the brake booster line. i'm curious if anything may happen at all... it's definitely true that it cleans the carbon build up throughout the motor (extensive testing and research from various scientists and enthusiasts), but engines tend to build up carbon in places that don't affect it anyway (pockets and such)... it's always good to clean out the carbon, anyway.
