Prepper vehicles and black diesel

[randyt]

Here is a interesting podcast on utilizing older USGI diesel trucks for a prepper vehicle. There is talk of using old motor and cooking oil as fuel without turning it into bio diesel.

Some diesel vehicles will run on ATF....after cleaning to get rid of any particulates.

Blends of ATF and diesel are actually considered a cure for some diesel faults.

A quart of old style ATF added into my 36 gallon fuel tank would get me about 1.5mpg more than running without it, and ATF has a lot of detergents so it helps to keep the injectors clean.
However, when oil prices spiked about 15 years ago so did the cost of a quart of ATF, actually ATF spike considerably, so it wasn't worth it for me to use it regularly. I haven't checked prices lately, mainly because oil prices are so high. But working on my various vehicles the past few years I noticed that most newer varieties of ATF have added friction enhancers so I am not sure how that would be good in the fuel system and in the engine. If oil prices drop next year (hopefully when we drill baby drill) I will check pricing on the old formula ATF again.

My truck takes 3 gallons of oil, plus the other vehicles I work on all use 6 or 7 quarts each. I filter my old oil and dump a few gallons into my mostly full diesel tank and let the engine "recycle" it for me.
