2010 Is250 Improved Gas Mileage

[ihateduke]

My wife just got a 2010 IS250 RWD. I was curious if there were engine mods that I could do to improve gas mileage? I'm assuming that switching to synthetic oil may help. What about a new air intake? Upgraded computer chip? Anything else?

Drive REALLY slowly?

Drive in winter mode!

driving habits will do more than any mod you can do to the car. Common sense...starts and stops...slowly, conservatively. Keep tire pressure up, but with tpms, thats easy. Maybe a K&N filter. But really, the way you drive will do way more than any "mod".

FWIW, our 09 IS 250 AWD consistently gets 27 to 29, with more on a trip...they really can be very economical cars!!!
