Over the past few years we have seen a huge increase in the instances of fuel related problems in the golf carts we service.
These problems have been attributed to E-10 (10% Ethanol added to our gas). Golf cart engines with carburetors, as well as, most small engines were not designed to use E-10. E-10 fuel efficiency can be reduced by 2 to 40%.
Some of the effects we have noticed: stalling, hesitation, smoke released from exhaust, clogged fuel filters, clogged carburetors, damage to fuel pumps, disintegration and dissolving of engine rubber and plastic parts (hoses), and drying-out of parts.
Ethanol in the gas attracts water from the atmosphere. Rapid temperature changes causes the water suspended in the gas to fall out (phase separation), causing stalling, and your cart to run roughly. This process also reduces the octane in the gas by as much as 4 points (if the octane level is 89, it can be reduced down to 85).
Ethanol reduces efficient combustion, which decreased performance, leading to stalling, and your cart running roughly.
As the ethanol in the gas tank ages a gum forms leading to clogged carburetors and fuel filters. Clogged fuel filters and carburetors rob your cart of power.
The shelf life of E-10 is 3 MONTHS under ideal environmental conditions. Fuel discoloration is a sign of contamination caused by the release of: rust, dirt or sediment, symptoms of "bad gas". The ethanol in fuel speeds up this process.
To help prevent E-10 problems:
We recommend that gas carts are serviced yearly:
