Issues to be aware of regarding adding acetone to fuel in the case of diesel engines as it pertains to water ramficiations


Diesel Acetone & Water Emulsification

(October 18, 2005 8:59 PM)


Before using Acetone in a Diesel engine, I would make sure that you have a filter (water separator filter) that will remove any emulsified water from the fuel before it enters the fuel pump or goes to the injectors. I posted several other messages last week on this and I stated that people with diesels need to have a water separator. I have learned over the last week that you can buy a non-standard water separator filter that will remove emulsified water and regular water from the fuel. It goes in place of your standard Primary Fuel Filter. I would hope that they would have a filter for your particular application. You can contact Fleetguard and they should be able to help you get the proper number for the replacement filter to remove emulsified water from the fuel.

I found that I didn't have to install a separate water separator on my 1999 60 Series 12.7 L Detroit engine. All I have to do in my case is use a different filter at my next 15,000 mile oil change interval. Instead of the standard Primary fuel filter, I will now be using a FS-1212 Primary water separator filter, the secondary filter remains the same. I will be using Acetone fairly soon, but I have some other testing to complete first before adding the Acetone. I will post my results when I get them, after completing my current fuel mileage tests on my current changes. Currently I'm at 500 hp carrying 42,000 pounds (77,000 pounds gross) pushing a flat nosed 65+ foot brick down the road, I'm getting as much as 8.2 mpg assuming I'm trying, while everyone else around me is getting 4.6-5.7 mpg, no matter how hard they try. 3300 miles a week at 8.2 mpg instead of 5.7 mpg at $3.20 a gallon is saving me a minimum of $564 per week. Every tenth of a mpg is more money in my pocket. I can't wait to see what Acetone can do for me and my wallet!

I hope this helps.
