Nah, its the older 2.2 before the ecotec.

Well, a few miles with a scangauge will tell you a lot!

1) 45 mph and locked trans is WAY better than 40 mph unlocked. We're talking ~15% increase in FE. This just reinforces the thought that locking the trans is super important.

2) The trans will stay locked at engine loads up to at least 80%. This means accelerating with the trans locked is totally doable. Clutches care about torque, not horsepower.

3) It actually runs about 210F when fully warmed up. I might want to look into this to see if there are any issues. This seems very warm. I want to make sure the radiator fan isn't kicking on a ton to keep things cool.

4) Neutral idle consumption is about .36 gph. Keeping it in drive while not moving is .39 gph. So, there is about an 8% fuel consumption reduction from shifting to neutral at stop lights.

5) P&G with neutral coasting at in town speeds 25-35 mph is effective.

6) Its still not that easy to top out a heck of a lot more than 30 mpg.

Mpg in to work this morning was 31.6 mpg, a significant jump (thank you scangauge!) since yesterday (27.2) with nearly identical weather. Ambient temps were mid 30F.
