Re: Does sugar in the gas tank actually disable a car?

Greetings:

Your question is an interesting one. I asked a number of our scientists and 
engineers that are doing automotive research your question and they all 
have heard about the problem yet no one could recall any actual information 
on the subject. A literature search and Web search on the subject also 
found no real references. Finally, I located several chemists that agreed 
on two probable answers to you question.  

Sugar (sucrose) is soluble in water and pyrimidine (C4H4N2) and it is not 
soluble in hydrocarbons (gasoline). This suggests that (1) sugar granules 
in the gasoline will accumulate and mechanically clog up the small orifices 
in carburetors and injectors and/or (2) the sugar will dissolve in what 
ever small amounts of water it encounters in the fuel tank or fuel filters 
and form a thick syrup which will also will clog up the very small fuel 
atomizers. So even small amounts of sugar the gasoline will eventually be 
accumulated and clog up the small orifices!

I’ll check around a bit more and if I find any more information I’ll e-mail 
it; however, accumulative mechanical clogging in the fuel distribution 
system appears to be the culprit.
