Winter is coming...blend gasoline that is. - Gasbuddy Gas Prices Expect a tick down in prices and MPG as winter blend comes as early as 16-Sept (not sure if that's everywhere or what). In winter we get more butanes (lower energy content) which expands the volume yield so that brings down prices. Of course, the lower energy content is hard to see (at most 1-2% less MPG) but the other changes with cold weather (thicker lubes. higher tire rolling resistance, etc) all combine to give a quadruple whammy of MPG lowering impacts.
Just hitchhiking on a thread: Apparently between September 8 and 10 50+ Chevron stations were selling premium gas that was blended with regular. Big whoop as far as I'm concerned, but for a lot of folks buying premium, maybe when they notice no change...
Meh. I like me some low gas prices, but that's probably going to happen now anyway. BTW....I don't consider $1.8x per gallon to be especially low, but I'll take it.
Perhaps gas will be less than a dollar when I finally buy my PIP2 and start plugging it in at 8+ cents per kilowatt.
AFAIK, we do not have "winter blend" in Seattle. We do have 10 percent "corn" all-year. At the moment, it is about $2.25 per gallon. About the same price I paid on a biz trip to the MidWest last week. I put the corn stuff into the car, with misgivings. I buy ethanol-free for my yard tools (chainsaw, brushcutter, weedwhacker, generator, etal). The whole corn into gas thing is a real scam as I far as I can tell from the things I have read....
So, I am still not sure about this whole winter thing, but I did find this from AAA, which is probably as accurate as anything...but...apparently, even in Seattle, we probably get some sort of winter blend....since California apparently does, also: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CB4QFjAAahUKEwinzqujoZ3IAhXYKYgKHZDqBJY&url=http%3A%2F%2Fnewsroom.aaa.com%2F2013%2F06%2Fwhat-is-the-difference-between-summer-and-winter-blend-gasoline%2F&usg=AFQjCNHIh5XKWJ1GevtgZJYJhAJHee4qIQ
