You can buy pure soybean oil from Smart & Final in 5 gal. jugs for about $13, or just over $2.50/gal. And they just had a newspaper insert $5 off coupon on purchases over $25 good through Jan. 30. So that would bring the price down to around $2/gal if you buy two jugs. It will last you for 10 tanks if you add a gallon per tank, creating basically a nice B5 blend. That's what I'm doing currently  |
That blend would not be "B5" or "B" anything. "B" stand for biodiesel, very different than SVO. The soydiesel mentioned is Biodiesel (NOT straight vegetable oil), or rather, transesterified veggie oil (thinned by chemical removal/replacement of the glycerol in the veggie oil.)
With that said, you CAN just dump in plain soybean oil, but it will RAISE the CFPP/Gel point of the fuel MUCH more than Biodiesel.
The $'s quoted for the soydiesel is about right for current nationwide B100 pricing. Many studies have found that 2% Biodiesel (NOT just straight veggie oil) raises the lubricity (BB tests) over 30% ABOVE that of normal sulphur diesel (pre-ULSD levels.)
So the guy re-packaging in one-quart containers is a good idea, but the cost will be up there just because of packaging.
I'd suggest saving one-quart plastic containers (motor oil, dried-out empty water bottles, etc.) and buy 5gals of B100, then split it into the one-quart containers and keep in the trunk for every fill. WAYYYY cheaper than ANY additive on the market and will increase lubricity and cetane.
