Let's build a list of ideas for ecomodding and hypermilling rental cars.
1)Bring an air pressure guage and put tires to max sidewall.
2)See if you can manually push the wipper blades under the hood lid.
3)Bring a piece of cardboard and some zipties and fashion a partial grill block.
Bring something to cut the ties when you stop to fill up before returning the car.
4)Stop at a gas station (not right at the airport since they are more expensive) and top off the tank. Then watch the guage and see how many miles before it gets from past F back to F. This is how far you stop from the airport on your return to fill up.

Please add more ideas.
