Customer had brough in a JD combine into the shop to have new head gasket and injectors replaced. The fellow cam back a few months later to have the engine rebuilt because it was due. When I cracked it back open I was amazed at how clean the top end was. Their was little to no carbon buildup inside the combustion chamber or on the piston heads, clean like running propane. I asked him what he's been running in it and he pointed me to Clean Fire. We've been supplying it ever since.   

After experiencing how smooth my diesel engine runs and how quite it sounds when I start it up from a cold start, I don't feel comfortable running my equipment without Clean Fire in it. When the cold weather sets in up north it feels good to know the top end is getting lubricated.

With my equipment that we have on the farm is seasonal and can sit for a time. I would always run into problem when I'm trying to harvest with my combines, water contamination was suffocating my engine and left me stranded in the field a time or two. After running Clean Fire every fill up I started to notice less and less water being caught in my water separator. I stopped using it and sure enough a couple tanks later and the water had returned. Got back on the minimum dosage every fill up and haven't had any more water problems! She runs good!  

We have been using Clean Fire for the last two construction seasons.  We have treated over 200,000 gallons with Clean Fire. 

Clean Fire improved fuel economy in all of our tests. We ran a MT865B Cat Challenger with twin Noble 17CY scraper pans. The machine has a 510 HP Cat C18 ACERT Tier 3 engine. 

The machine had the same operator and the same working conditions throughout the test. 

With straight #2 off-road diesel the machine used 18.35 gallons/hour. With Clean Fire added to the same fuel the machine used 16.23 gallons/hour. Your additive improves economy period!
