So in my continuing quest to try everything I can with my new favorite thing,,I towed a buddys broken jeep (go figure) about 80 miles to another friends house to begin repair. I rented a tow dolly from uhaul, and broke out the tow straps and comealong and got it hooked up, put transmission in power mode, and took of down the freeway. I must say that at cruising speed I didn't even notice the 3000 lb jeep, stopping took a bit longer and starts I could really tell it was back there. over the two mountain passes involded I kept speed at about 50mph with the o/d off cruiser did great, I have been testing a fuel addative a friend helped develope and got 12.5 mpg. I was cruising at 65mph on the flats never went over 70. The best tank I got before the addative was 12 flat babying it around back and forth to work and store, and a quick road trip to the same destiation as the jeep delivery during my stuck addventure, I got 11 with it ideling for roughly 3 hours and lots of heavy pedal usage on unleaded gas, more to come on the fuel addative.. With the weight of the doly/and jeep it still sat prety level, sorry the pic from the side did't turn out so good but here is one at the drop off..
