Has anyone converted their R134a refrigerant to hydrocarbon refrigerant to improve mileage while using the A/C? Going throught the literature, use of A/C can reduce mileage by 15%, and use of the more efficient hydrocarbon refrigerant is about 30% gain in efficiency through lower head pressure and fewer cycling of the compressor. The conversion should improve your gas mileage by as much as 3mpg when using the A/C. Is their any testimonial out there on this type of conversion?
