I agree 100%! I myself just have to go off the past & present reputation of the company I'm purchasing from. Some what like going to church: (Having FAITH in something you strongly believe in)! It's all about that feel good feeling! This is the reason I mainly run Schaeffers & Red Line! HSS (Diesel Extreme) is used mostly due from the review of Shawn from mopar eco diesel & my Uncle. (Nothing More) SyN Disclaimer: I never have or will attempt to convince other diesel owners to use diesel fuel additives! I don't care if others do or not - it's none of my business - nor do I attempt to make it my business! I'm not wired that way! Edit: I started this thread for others whom use diesel fuel additives to share their personal experiences not for others whom don't run them & feel they need to vent their (Once again) Opinions. Good Luck & Best Wishes to U & Yours. If & When I have issues due to adding a little bit of Diesel fuel additive @ each fill up - I will be sure to post back within this very same thread & begin eating a A$$ load of crow!
