Ok, sounds like if it is going to sit for an extended time 2weeks+, then drain it?
So the next question is what do I need to switch over and is there a reference to it?
Btw, there is an E85 station just down the street from me
It's not so much based on a "TIME " frame ... 2 weeks you won't see a issue.. 2 months with drastic fluctuations in TEMP and HUMIDITY and yes you should have a additive or drain it and add unleaded with additive.. TEMP and HUMIDTY fluctuation has a far greater influence than TIME.
It's not METHANOL .. BIG BIG difference ... I let E85 sit in one of my sleds OVER 3 months that had Seafoam in it.. just fired it up every now and again with ZERO issues..
Methanol you don't have that luxury.. you have to get it out as it will destroy things pretty quick.
Who said anything about methanol? I would rather do time frame than play meteorologist to figure out the saturation in my gas tank.
the theory is that water will accumulate, water will sink to the bottom of the tank, and the fuel pickup will pick up water and not the fuel.
Fuel pump pumps water into motor and water does not compress BOOM! hole in something!
I would like to run it but there is a cost to performance along with maintenance. If you don't do your due diligence before you take something like this on, then you should expect surprised. Now cut me a deal on your 80#s.HUH .. .Seriously .. HOW are you getting water in a non compressive state in the cylinder for it to go BOOM.. doesn't it have to go past a fuel injector first ??? It would be atomized at that point and going into a cylinder that would instantly turn it into a gas ...
The car may run like crap with water in the fuel.. but you certainly won't hydrolock a motor from the little to no water found in your ethanol fuel...
WIVES TALES ... and rumors ...
IF you have a Turbo Buick , and have E85 available... and you still aren't running it.. you've completely missed the boat.
In my opinion running a Turbo Buick on 91/93 pump fuel is a complete waste of time .. might as well drive a 4 cylinder focus
you wanna run fast or run pump fuel.. pick one
E85 Really lets the cars run to their potential.. NIGHT and DAY different from 93
