Low sulfur fuel and additives
Mike, Dan, That would be a 30% mix for the winter blend.
I doubt that the winter blend went South, maybe, I doubt it. I just used it when the temps were in the teens which was not often and if so for a short time. My mix was only around 7%, but it worked. If you "slide" diesel or kerosene between your fingers, the diesel, #2, felt slipreer (more slipery) Before Gunk we would use kerosene in a pump sprayer to act as solvent to clean grease off a motor, water hose spray down. bob janes, greenville, sc --- In WanderlodgeForum@yahoogroups.com, "Dan Darst" wrote: > > Yes Mike.

Low sulfur fuel and additives
FWIW my car manual specifies #1 fuel for temps under 32*F, or to mix
30% kerosene with #2 diesel for temps between 14*F and 32*F, ... 50/50 for temps below 14*F. Never to mix #1 and kerosene. Many of us on various Mercedes Diesel forums have had fuel leaks, pretty common, I've had two minor ones this fall on one of my cars. The incidence with existing vehicles will likely increase with the ULSD especially in older o-rings. Not much can be done about it, various additives could in theory help, more can be learned from Biodiesel and WVO forums as there are additives used in cooking WVO such as benzene and naptha that could increase seal swell. ULSD is here, it is staying. Watch for leaks, raw diesel is an easy smell to notice just after shutdown. If you smell raw diesel you're getting a leak, find it. Increased fuel consumption and rough idling are other indicators, and watch the engine oil for leaks into the oil which I know from experience can grenade an engine if it gets enough diesel oil to hit the crank/rods and run-away (no way to shut down). A drop in oil pressure might indicate thinning oil from a leak. With ULSD it is now more important to use algaecides, watch filters, use quality oil, and notice smells or fuel mileage changes. - Jeff Miller in Holland, MI --- In WanderlodgeForum@yahoogroups.com, "one_dusty_hoot" > > Mike, Dan, That would be a 30% mix for the winter blend. > I doubt that the winter blend went South, maybe, I doubt it. > I just used it when the temps were in the teens which was > not often and if so for a short time.
