We run the Bio in our fleet trucks and all diesel powered equipment. I dont have the ratio at this time, but will ask monday. When we first started running the Bio. We were going through fuel filters like mad. Now its normal filter service intervals. 2001-2004 fords seem to be doing ok. We have had injector failure on 2 chebys with Cat motors, now another one? still trouble shooting. Our steerling trucks with Mercedes engines seem ok so far.
