We seafoamed the tank and crank case and had an oil change with 5w30 Full Synthetic today. Not much modding has been done lately, I did however notice that when going down hills that if I stick it in low gear the fuel injectors are turned off and the engine goes into open loop and I've been using that.
I've also been able to get over 30 MPG on the highway on short trips by going slower (43-50 or 55) and some pulse and gliding.

Sure, cold weather may play some part in that, but when was the last time she got a tune-up for that minivan?
On a related note, I recently purchased a 2005 Dodge Grand Caravan with a 3.3L V6 and that damnable 41TE slushbox. Of course, I'm going to squeeze out every bit of FE improvement as I can. Already looking to install an intake heater.

Probably since never, I think. We had an oil change at about 132 or 133k miles and now it's close to 137k miles, That made a big difference. But I don't recall spark plugs ever being changed in it and we bought it used.
