Dont know from the top of the my mind but it was noticeably better in terms of mpg. Driving habits were about the same. Only thing that was different was that it has gotten a lot colder.

Well...stop letting it warm up. It doesn't benefit the car.
Start it. Drive off.
Drive at lower RPM til the car warms up. Then drive normally.
I shift fairly low...like at like 2-3K if I start driving in like...sub zero weather. Then when the coolant temp starts moving, I shift at my normal 4Kish. Once its warm, a normal 1-2-3 shift happens anywhere between 4K and 7K RPM.
I store my S2000 for winter. But fall/spring temps around here are between 10 and 60 degrees F. Sometimes in the same day.
If your car was in the effing arctic circle and the polar bears were after you...it may need like 30-60 seconds before driving off.
You don't need to warm up a modern car.

Are you on 66 in traffic? If so you're going to get awful mileage in bumper to bumper. I average around 23-25 in the area but I reverse commute out of DC and never sit.
Fill the car completely, putting 4 gallons won't tell you anything because you'll have no idea how much you actually use. Top off the tank, drive around until 1/4 tank. Top off tank again, then come back and tell us what the mileage is. What octane are you using, where are you getting gas? 18 isn't great, but I'm not sure I'd be jumping to something being wrong yet either.

I can't believe this thread is still going strong! LOL
Check your filters too if you haven't. Engine air filter. If clogged up you will get reduced performance.
Fill up FULL and go for a long highway drive into the country and back then fill up again and see what MPG's you get.

TFW the OP did the math correctly and realized his car was getting 25 MPG all along & doesn't want to post about it bc he looks a fool.
