dcduncan118 Report post Posted April 2, 2013 I've spent over two hours speaking with customer service reps from American Coach, Spartan and Cummins looking for what I presumed would be an easy answer - what additive to put in the fuel tank of my new 2012 Revolution with a 450 hp Cummins? The local Cummins store suggested a microbiocide (sp?) they carry for $156.65 a quart. Apparently a quart will treat 2500 gallons? The catch was he doesn't carry it and I'd have to buy four quarts. Surely there is a better answer for treating diesel fuel to prevent algae from growing? Would appreciate any thoughts. Share this post Link to post Share on other sites

hermanmullins Report post Posted April 2, 2013 Rich, Can you put one of these in your tank as a preventive? I have also heard that you have to be very careful using these products. See you in Gillette. Herman Share this post Link to post Share on other sites
wolfe10 Report post Posted April 2, 2013 I add a Biocide anytime I will be storing diesel for more than 2 months in the summer or 3 months in the winter. Also, store with tank full to minimize condensation. The only other time I would add a Biocide is if I see an algae problem (black stringy "gunk" in primary fuel filter bowl. It is basically "weed killer" so it is not something I would get on my skin. Brett Share this post Link to post Share on other sites

LewsRoo2 Report post Posted April 3, 2013 So do the manufacturers recommend any product or guidelines without spending $150.00 a quart for additive P.S. How do you add your coach and toad info to your tag or blog name. Thanks Lew Share this post Link to post Share on other sites
wolfe10 Report post Posted April 3, 2013 Lew, Just do a google search on the products Rich mentioned. $15-20 should do it. BTW, diesel boats have the same diesel storage issues, so check with any marine supply store-- they should have a Biocide in stock. Share this post Link to post Share on other sites
five Report post Posted April 4, 2013 A biocide is what you need, any marine store will have it: http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?productId=14353&catalogId=10001&langId=-1&storeId=11151&storeNum=50366&subdeptNum=50396&classNum=50399 Share this post Link to post Share on other sites
BillO Report post Posted April 9, 2013 Many farmers with diesel equipment face the same issues. As a result, I've had good luck finding it at Tractor Supply stores around the country for a reasonable price. Share this post Link to post Share on other sites
