I've been running a 2005 Chevrolet 6.0L fuel injected van on diesel:gasoline mix at a ratio of between 30:70 & 40:60 successfully. 50:50 was too high when the ambient temperatures were -15 deg. F., but the lower ratios have worked well. Cold starting is OK, although it is necessary to allow the engine to warm a couple minutes before driving away to avoid stalling. There is no apparent misfire and fuel economy is improved. My experience using a blend in this range has been an increase in miles per gallon of 10-20% over straight gasoline. If the improvement were due only to the difference in specific heat, then the increase should be only slightly over 10%.
