Other What is all the YELLOW stuff in 93 pump gas ethanol ?

When you pump Hess, Sunoco and Murphy USA 93, half of it flows very yellow out the nozzle ? I noticed that Chevron 93 is clear ? Just wondering is it additives or ethanol, anyone know for sure ?

As it absorbs water, or is exposed to sunlight, it turns yellow. Go to the place with clear gas.
When I last cleaned my boat motor carb it had what looked like coquina sand in the bowl area. But when I grabbed some and rubbed it between my thumb and forefinger it was more like little beads of yellow jelly.

Near me there are a couple stations "on the street" (near boat ramps) that have a "rec gas" pump.... muscle car owners use them too.

Highly recommend for 93 octane users.
 
I found this later online, don't know if this is the answer ? Source is an Amoco tech employee...


"Amoco Ultimate gasoline does go through a proprietary process that

removes the PNA's which are basically poly-nuclear-aromatics. These

are responsible for the slight yellowish color in gasoline and are

ultimately responsible for resid(tar-like) deposits that can

accumulate in your injectors, etc. "

fugg that.. I found an ethanol free pump with 93 octane... look for "recreational" gas.
