DFA FAQ (Frequently Asked Questions)

Please check back often as we'll continue to post common Q/A here.

Q1.    Is it really possible to run used cooking oil in my diesel?
A1.    Most certainly is. Rudolph Diesel who invented the compression engine originally designed the Diesel to run on Peanut oil

Q2.    I live in the Arctic, and only drive 2 miles to work, will this system work for me?
A1.    No it won't. Or at least not well. No matter how hot you can heat the oil and how quickly, the motor has to be hot, or the oil will lose all its heat going through the rail, and injector. And once again, you are injecting cold oil that leads to coking and accelerated engine wear.

Q3.    I live in San Diego, and it is never cold here. Do I need a heated system?
A1.    Yes you do. WVO is simply too thick to use as fuel until around 180 degrees. You may be able to forgo the tank heater, but still not recommended. The motor will run, but it will not burn completely and again lead to coking until the motor is up to temp.

Q4    Can I run performance tuners and parts with this system?
A1.    Absolutely!! I myself have most of the cheap mods, intake, exhaust, edge tuner and some others.  I have run an official best of 15.2 sec. @89 mph in the 1/4 mile (before lift and tires).
