You probably already know this, but if not, you might want to make sure he washes his final product. He probably does, but it's best to be safe than sorry. A simple wash can fix a lot of the problems of a less than optimal BioDiesel process.
You should get a half a million miles (at least) from your Cummins on straight B100. It would be a shame to get anything less than that because of incompletely washed fuel. And bubble washing is just too darn simple not to do it.
I use a baja filter in addition to my water seperators and filters on the truck to be safe
Good Man! Sounds like you know what you're doing. Just check up on the washing to be sure.
Yep I like the cummins engine. I have some serious aftermarket goodies duct taped on it like a powered pre-oiler vs the accumulator type, dual water seperators, magnetic drain plugs and sump dump plugs to keep any scrap metal out of the earl and use nothing but amsoil products. Oil gets changed once a month vs mileage variables.
Alledgedly Toyota is in talks with CMI (Cummins) to pick up their engine when Mercedes makes Doooooge use the german diesel vs the cummins in the very near future....alledgedly of course....:o) A HD Crew Cab Toyota Tundra with a cummins would be a nice rig to have.
I'll share yer wash concerns with my source.....thanks for the info !!
Stay safe !
