Fuel Mileage

It's been a bit of a boring few weeks - no new developments, no new mods - just commuting to work and that's it. A while ago I found myself getting gas at a different location (& different brand) than I normally do; I usually fill up with 76 Premium (which is only 92 Octane here + of course the lovely 10% ethanol...) at various gas stations, but instead I filled it up with Chevron 92 Premium. Driving around for a week or so on that gas I checked my avg fuel mileage and I'm seeing 13 mpg instead of my usual 11-12.. now that's not much to write home about, but I still found it interesting.

Then I've recently found there is 1 particular '76' location where with the gas from that station I swear my car runs/idles smoother and I saw even a 13.5 mpg average - I've repeated this experiment 3 times now and between the two different 76 stations I frequently visit, this one consistently gives me a smoother running engine (at least that's what It sounds like to me) & better mileage. Obviously this measuring is not a fully scientific method and there willl be tons of people saying : Premium 92 at one place is the same as Another or All brands are the same etc etc, but I tend to drive similar/the same enough on my commute and based on how I hear the engine run and the dash-display I have to believe there's something to this. So it looks like I've found a new place to get gas ;)

Also just for fun - one day I happened to get gas and did only in-town driving. Lots of errand-y stuff and it totaled out to be about 13 miles all together. The gas-mileage for that little jaunt was a whopping 5.3MPG!
No wonder that while I can hit 22-25mpg on the freeway, as soon as I get into town it just starts to plummet down towards the low teens!

So today's word of advice: If you're concerned about fuel-economy... don't build a stroker ;)
