I have used all of the lubricants. I started out using the Super Diesel Klenz. When Power Flo Klenz was introduced I switched to that. I have no experience with the other diesel fuel additives. Years ago I did a detailed fuel economy test. The results were positive enough that I was convinced that the additive at least paid for itself. Currently I have a 1995 Chevrolet 6.5 TD with 255,000 miles. The pump was replaced at 70,000 and 110,000 miles. Both times because of electrical problems. I have rebuilt injectors once at 110,000 miles. My Dodge Ram 3500 (which gets A LOT of hard pulling) has 145,000 miles with no pump or injector problems. I realize those experiences may not be extraordinary but I have been satisfied with the performance. I know the lube engineer at Central Petroleum Company. He is a "straight-up" guy who knows his business.
