Biodiesel in Winter

Cold weather is here: keep your vehicle on line!

It is time, once more, to switch to a lower blend of biodiesel.

For those of us who have been running B99 biodiesel thru the warmer months, now is the time to add some petroleum diesel to our fuel tanks to make sure there are no gelling problems.

Pure biodiesel will gel at colder temperatures; if you are having trouble starting your car in the morning, add some petroleum diesel to your fuel tank and let it mix in there. At the warmest part of the day, start up your car and then let it idle for a while.


SeQuential's recommendations are as follows:

Outside Air Temperature:

 Below 40F, but above 30F = B-50

Below 30F, but above 10F = B-20

Below 10F = B-5
