I did some test on a test stand over 7 years ago with Jet A and Kero with a Pegasus..
And the result were exactly the same.. Both ran the same temp and powered up
exactly the same..

One thing I like about Jet A is my 55 gal drum does not have one bit of growth
after many many years.. I don't know if Kero would have stopped any growth
but I have first hand experience with junk growing in diesel tanks.
