So I am very new to "black diesel" and doing my homework... Man you guys/gals on this forum are sharp!
My question is can you cut the WMO with JetA (aviation fuel)?
I plan to try the 85/15 mix... Also, my truck is an 05 powerstroke. Any specific issues with this 6.0 that I should be aware of? Thanks for all the great info.
I guessing that your thought of using jetA could only be the result of a cheap source. When blending WMO with other "fuels" the 85/15 ratio was originally for using RUG (regular unleaded gas). I think it is generally preferable to use ethanol free RUG. Other fuels like K1, jetA or even D2, require a bit of a different ratio.
A few of the ways to determine a proper blend are to use the properties of diesel and make a blended fuel that approximates those, namely viscosity and specific gravity. You can use a zahn cup to measure viscosity (or any small cup with a small drain tube that drains a specific quantity of liquid in a certain length of time). As an example: you dip the cup in the fluid to fill it, lift it out and measure the time it takes to drain out, say 15 secs.
Or some instrument like a battery hydrometer can be used to measure specific gravity. There are of course other more technical properties of a fuel like cetane rating, volatility, and flame propagation, but a usable blend is attainable by the simpler methods.
W85/80 is a pretty trouble free fuel requiring little to no special changes in any mechanically injected engine. I've got ~6k miles on my '93 7.3 IDI running W80-85 (RUG blend) 99% of the time.
As far as your 6.0 goes I can only guess, but at the least you'd have to have a tuner chip with the proper tune for W85, there are also issues on some diesel engines regarding optical sensors that don't like fuel it can't see thru like any WMO blend.
