Ok, my old truck to be its age only has 225k on it. Well recently I been having hard start ups. And rough idle. I tried several diesel additives. No results at ALL. This is where I was totally shocked. Bought a bottle of diesel kleen. Used it. Within 20 miles, I could tell a noticeable difference. After two tanks later using diesel kleen. Problem is totally gone. And has been running great over 6 months after using this product. It really works…
