using the fill up amount has too much variability, skirts should not make that much difference. i found that high pressure tires, 38-40psi, and removing the toe in had a big effect for me, wind resistance is the biggy, so speed is key also. it is hard to drive below 60 though. rain is big too, but snow is the worst on mileage. but it seems like you should be able to get 34 out of it because of the weight, but it is over 2 liters right? best i ever got out of stock car was in a 1984 CRX hf with the 1.3 liter engine, that was 49mpg, freeway, 60mph.
