Negative. If the truck is driven on the highway, it needs to have the blue/green tax stuff in it.
Grain trucks ect. can not run the red stuff on the highway, or it is fine time. OSHP sat down the road from the local elevator once and did random samples. Handed out a few fines while they where at it. (fuel tax fines, overload fines, vehicle safety fines, ect.)
My dad got busted for being 200# over on the front axle, even though his GVW was still under the limit.
