Sierra, I've seen that also in the Raptor Supplement manual on ford's support page. It says....Here's an interesting piece of info...put my vin into that decoder and for fuel
Type it says "flexible". Now unless I missed something on here up till now the 6.2's in the superdutys were flex but not in the raptors. Did something change for '13?
"OCTANE RECOMMENDATIONS
Regular unleaded gasoline with a
pump (R+M)/2 octane rating of 87 is
recommended.."
Also says...
"Fuels with octane levels below 87 are not
recommended. Premium fuel will provide improved performance and is
recommended for severe duty usage such as trailer tow."
