Will I be able to run my bone stock 2000 Expedition w/4.6l on E85?? Would it cause any problems??

Thanks

I'd go by what your owner's manual says. If your engine isn't flex fuel I don't think you can run the e85

 

The 85% alcohol will damage the metal, if it is not stainless steel, and gaskets in your fuel system,. Alcohol is corrosive, even the 10% could have an affect on some older vehicles causing $$$ for repairs which could be more expensive that the value of the vehicle. The higher the alcohol % the quicker the damage will show up.

 

This vehicle is NOT Flex-fuel compatible.

You risk damaging the fuel pump, fuel hoses, injectors.. etc... (although probably not if you accidentally used it once) but what's REALLY going to cause problems is it's going to run rough, hesitate, misfire, set a check engine light, and possibly damage the converters as a result.

Not a good idea. (Ideal air/fuel ratio for gasoline is 14.7/1. For E85 it's about 10/1. You need more volume to produce the same power, and your vehicle isn't set up for that, therefore you'd be running extremely lean, if at all.)
