hey RCaddict80 the fuel im using for all my trucks is Opti fuel 20 SUPER SLV as i bought a raptor 50 heli this fuel does both they run brilliant on it. i noticed when the 8.0 engine is cold it always loads up & stalls with carb set at factory settings but it was ok when at operating temp . i have now replaced the 8.0 engine for a .32 it does not load up & stall when cold
when the fuel in the tank is almost empty, thats the peak of the temps in the engine. when it is almost empty and the temp is at 270F, this means that when it is 1/2 full, it may be around 250-260F, and when it is full, it may be around 240-250F.
your engine runs hotter using 30% fuel this means you will be doing an engine rebuild sooner rather than later
