Experiences with Pro Long Additive?
My high milage (130K) L98 motor is getting a little noisy. I've seen a product called Pro Long that is supposed to work miracles :D Has anyone any experience, good or bad? :confused:
Thanks,

I used it in my truck for a few years, couldn't tell you if its bad or good, but my 95 Chevy 4x4 has 133,000 and never had a problem!

I thought the FCC cracked down on these guys and they had to change all their ads. I'd never use anything but Mobil1 10w-30 in my Vette.

My father uses an oil called Tuff Oil or something like that. it's PTFE just like the rest of them, except this one claims that the particles are 1/10 the size of the PTFE in other addatives, blah blah blah. Probably still junk, but much to my amazement, when my father poured a little into his crankcase, the idle of the truck came up a couple hundred rpm until the computer caught up and brought it back down. Since this stuff is suspended in motor oil, the viscosity difference shouldn't have caused the idle to increase like that. It made my father a believer. I'm still skeptical, but this one brand does seem to have more actual test merit than all of the others.

PTFE doesn't bond to metal unless heated to well over 800 degrees F. I don't know many engines that run that hot and if they don't they don't run long.

Re: Experiences with Pro Long Additive? (Vettman 1)
As a homebrew experiment I ran ProLong in my truck for about 50K miles, no idea what effect it had. Switched to Z-Max for awhile and immediately noticed a 10* operating temperature drop and faster cranking on sub-zero mornings. I've replaced every peripheral component at least once, alternator 3 times, fuel pressure regulator 4, but the motor itself has 133K on it now and runs better than the day I bought it, zero increase in oil consumption, if anything more power and better fuel economy. I should mention I've been running synthetic oil since break-in also. As another experiment, I intentionally ran the original AC-Delco platinum plugs until I finally noticed a performance decline AT 133 THOUSAND MILES :crazy: the 0.060 gap had burned open to 0.075 mostly due to missing platinum pucks.
All that said, I will be doing nothing of the sort to my Corvette.
