Q: Is ethanol bad for certain fuel system components in fuel pumps and carburetors?
A: Early on, some elastomers (rubber-like parts) and metal in these fuel system components did deteriorate over time. Very quickly manufacturers changed these fuel system components to be compatible with ethanol fuel. From time to time, this myth begins to circulate again, but it is not true. Today, all vehicle manufacturers, domestic and foreign, approve the use of ethanol fuels. The Z was built in the early 90s - so affects us.
Q: Does ethanol cause injectors to plug in port fuel injector vehicles?
A: This theory was never proven. Earlier fuel injectors of the pintle design could form deposits that changed the pattern of the injected fuel. This problem developed from injectors seeping fuel when the vehicle was not running. This formed carbon deposits on the pintle and caused even more leakage. This could happen with any gasoline. Because of this problem, injectors in most vehicles have been re-designed around the popet style and all gasoline is required to carry a detergent component to alleviate the deposit problem. I'll translate: Ethanol dicks up pintle injectors, but the detergents should clean them up... yeah right.
Q: Does ethanol use cause injector failure?
A: This seemed to be a problem on certain vehicles from 1988 to 1993. The manufacturers changed the injector coil insulation. It appears that this problem does not exist on late model vehicles. Ding.
