I have a 05 ranger stx but do not know if it is e85 compatable the 8th letter in the vin is a u not a v does that mean i can or can not use the e85 :banghead:

I think the U means that you can't. MY 2000 has the flex fuel system, and mine has the V. Call the dealership they will be able to tell you for sure.

"V" (Victor) is E85.
"U" (Uniform) is gas-only.

Just had my WA state emmition's test done 8-14-06, with the U as that 8th and on the report it was noted a an FFV vehicle! But then again, I have had to go through the WA state registration to change that U from a 4 for some goofy rerason, so this is not over yet!

Thanks for the info.. I have an 06 stx ranger. My letter is also a "U". According to www.e85.com, it is not a flex vehicle. Why would they only make selected vehicles flex? Makes no sense. Anyways, let me know what happens
