richontheroad@hotmail.com Report post Posted March 20, 2009 Similar to those used on diesel engined boats, and generators, is anyone using a diesel fuel polishing system similar to those found at http://www.ParkerFuelPolishing.com to keep their fuel fresh and free from water condensation and the resultant bacteria and sludge?

garykd Report post Posted March 21, 2009 Hi Rich, I use Stanadyne Performance Formula (blue bottle). Go here to read about the product and find a dealer. Stanadyne has several products. I have only 6K miles using the Performance Formula. It has increase my MPG from 7.2 to 8.4 MPG. Once I get this year's travel under my belt, I'll have a better idea of the product's overall performance. Share this post Link to post Share on other sites
