Toyota Repair/fuel additive


Mr. Ritter,
I have 2 Toyotas, 93 4x4 pick up and a 2000 Rav4.  We just moved to a state that uses 10% ethanol in the gas.  I have heard this causes a lot of condensation in the fuel tank and corosion through out the whole fuel system.  
Is there a  fuel additive I should be adding to eliminate this problem or something to help this problem?

Thank you,

Hello, I am not aware of any problems caused by 10% ethanol fuel mixture but I can't rule out that possibility under certain circumstances, if you decide to use fuel treatment use a Lucas product or use good quality fuel which should have rust inhibitors added.
