Well, of COURSE, you stupid idiot. If the autogas has alcohol in it, it will
read different. But you KNEW that didn't you, and you knew that gasahol isn't
approved for aircraft engines.

Just for you to research. What is the difference in dielectric constant (you do
know what that means, don't you) from pure gasoline to MTBE?

"Bart D. Hull"
shared these priceless pearls of wisdom:

-What if your autogas has alcohol or MTBE? Have you tried this
-with probes on your plane?
-
-The probes I have acquired have a slip of paper with them that
-mentions how to calibrate the gauge to the probes and warns about
-different fuel mixes showing different results.
