Well it has been a few days now since i did my oil change and i havn't been able to get the exact gain i have got MPG but i am getting lots more MPG now that i changed my oil. before everyday i drive to work and back my needle would move a good amount now it barly moves at all and i am filling up my tank alot less. It took me less than falf a tank to get to palm springs from LA and i was driving fast. the oil i used is Mobil 1 5w 30 and the mobil 1 filter for the base model RSX if any of you are interisted.

P.S. I didn't even know that just an oil change could improve you MPG so much can someone tell me why this is?

My gas mileage is horrible right now. I only have about 520 miles and I've had to fill up 3 times already. I use about a 1/4 tank in 50 miles. I hope when I break the car in more and change the oil later on I'll have better mileage.

Yes cars burn more fuel when you're breaking them in, as soon as you put more miles on it you'll get better mileage. Changing the oil could possibly improve mileage as well.

I switched to 5w-30 Synthetic and went to panama city, which is 200 miles from where i live and I only used 5/8 of a tank and i had 2 other people in the car!!! BUT, then again I've got 8900 miles on mine. I got mine as soon as the dealership ordered the first one!!!!! Mine is in the shop right now getting 15% Platinum, and a new black headliner!!!!

yeah, it'll get better, I was getting the same thing, but I have an intake and I still get good gas mileage now, but like I said, I've got a lot more miles than you though.

520 and 3 fills up?? wtf.. do you drive at 100mph constantly? or live around 45deg hills?? wut's the deal. i've been getting around 270-280 per tank since day one.

I'm gettin' about 27 mpg myself. But I got like 9000 miles on my EP already...

I've been told that you'll get much better milage after your first oil change, and changing you oil well before 5000 miles is a very good idea. It helps clean out all the worn metal filings you accumulate in your oil during break-in.

That's why I've been changing mine about every 2500 miles. I have to put the juice to mine pretty often here because of all of the crazy drivers. And plus a lot of 18 wheelers come through Columbus, So you gotta get it around them pretty often.
