I have several questions about specifically "Tufoil" engine treatment after reading about it in much older posts.
1. Does anybody reading this currently use it, or has anybody had a bad experience with it?
2. Is it okay to add to my high hour machine (20hp Kohler 2440 hours) and older truck 2000 Chevy K2500 132,000? I have been told in the past that on older machines that I should not switch over to synthetic oil at this point, would that be the same principle for this additive?
3. Do any chain stores sell it off the shelf? I do see it for sale online.
Thanks in advance
