On that subject (blending) - I ran across this today (below). It referenced the use of RUG as a potential problem w.r.t. flash-point.
I read someone's post in the past few days where the heating effect of recirculating fuel (as it cools the high-pressure fuel pumps in our Cummins) had heated his fuel, in-tank, in excess of 160F (about 1/4 tank). He probably had some other things going on, but imagine that scenario with low flash-point additives mixed in?
It's just another thing to consider when weighing the use of blending with SVO/WVO against the effort of making or the cost of purchasing biodiesel.
Diesel Fuel Discussions
Here are a few notable quotes:
"Adding kerosene and gasoline to diesel can have dramatic, adverse effects on the flash point, with minimal gains in the flow properties if the fuel already contains flow-improving additives. Regardless of what other people may advise, check your insurance policies before embarking on experimentation. These days, assessors for both vehicle and insurance companies these days are far more aware of the signs of the dilution of expensive diesel fuel by cheaper lower flash fuels."
"Thirdly, diesel in many countries has a legal minimum flash point ( the minimum temperature it must attain to produce sufficient vapours to ignite when a flame is applied. In all cases it's usually well above ambient ( 60C+, kerosene is 37C+, whereas gasoline is typically below -30C ), and anybody mixing a lower flash point fraction with diesel will usually void all insurance and warranties on the vehicle. The recent increase in blending fuels has resulted in significantly more frequent analyses of fuel tank contents from diesel vehicle fires."
So - be careful out there!! Especially as summer arrives.
