I am about 10000 miles away from my next service. Bare with me as I am converting from KM to miles but I had the 100,000KM service done at 120K and will do it again at 220K. that is plugs, transmission kit, coolant.

I will look into a better air filter, I am just using one provided by my mechanic, I beleive it is cotton based.

I also recently had my transmission rebuilt 100%. I lost 1st and 3rd, it is still under warranty but I am not sure if the transmission can affect the fuel economy.

I have 205,000 KM or 130k Miles on it.

Thanks for you input and please keep the suggestions coming....
