Hi Barry Welcome to Gadgetman Land!
(sounds of a circus side-show barker..."step right up folks, that's right, for just a dollar, one thin dollar come see the Gadgetman do his secret thing!") If ya tip the barker ya kin git a better seat...
Listen to Heysoundude, he's definitely on the right track. Your driving style as well as conditions like weather, temp, etc. play a major part in all this. Can't control Ma Nature, but you control how you drive!! You will find I'm sure it starts with mindset, you become more aware of how you drive. Cool you guys are relatively close, I'm all by myself in the vast dry American West!
OK for easy starters, check the tire pressure. find the press. rating on the sidewalls, try inflating cold to that spec. If it's OK, safe, etc., try adding say 5 lbs over the rating, cold. This reduces rolling resistance, you can feel it while driving. Pay attention to handling/braking, etc. I've added more than this before, you have to be your own judge w/ this. common sense...
And of course MPG Remedy is definitely worth a try, read my latest posts and others' in the new MPG Remedy thread here. I think I recall Ron saying a couple years back something about the Dodge hemi's having some issue about the PCV valve, location, mounting, etc. that present a problem, not exactly sure right now.
anyhow Barry, welcome aboard, we learn together. IF you can get up any pics of what you do, it is always appreciated by all. Glad to see more Canadians on here, you guys are gonna be our cold weather Experts!
