Lowering the differential ratio is expensive and will deteriorate cruising economy, but can improve low speed towing performance. May be you can switch back to gasoline when accelerating and towing. > > 3: Water temp in stop and go traffic a bit high can I remove theromstat or > get alloy radiator How hot does it get? If its below 210F (100C) you are OK. Remember, in terms of engine life, its generally better for your engine to run a bit warmer rather than a bit cooler. If you put your engine through a lot of labor when hot, you could switch to a higher viscocity oil (20w50). Provided that your engine works had while hot, you will not lose fuel economy, while your engine will be better lubricated. D^2
