Anyone seeing their MPG decrease lately?

I noticed that the info display on the Prius, which usually shows 43.8 MPG over it's 52K mile history, has suddenly dropped to an average of 38 MPG and the fuel price has skyrocketed too (It was $4.79 per gallon in West Covina, CA the past weekend.). Leno said it was $4.50 near his house. Wouldn't be surprised if it goes over $5 for the first time this May or so.

I don't know if CA moved to E-10 fuel which is supposedly less BTU than E-10, or no E at all. Just seems odd that the MPG drops a lot and the price rockets up.

Need to watch my bikes as one loop will kick the yellow "Reserve warning light" on on the S1000RR when nearing home. It might kick on far sooner (or jsut run out) if they are monkeying around with the gas formula since the beginning of the year.

I did note the Yamaha dealer's "E-free" racing fuel is $13 gallon now. Yipes!

From what I can see, the gas quality (mpg) is going down and the price is going up.

In our local supermarkets I've also noticed the size of packets is going down and the price creeping up.

I think it's called price inflation.

But take home pay is staying the same or going down, if you are lucky to have a job.

Yeah I have noticed a drop of about 1.5 mpg on the bike as well as the car. That is something that seems to happen each winter. Colder denser air and /or some changes for more oxygenated fuels here I think.

Oregon has had E-10 for quite some time, one or two years. I noticed a 20% drop in fuel economy after it. Several local stations have no E super as allowed by law, for boats, mowers and hummm motorcycles, noticed a +20% gain in mileage when using it. More gas, more pollution, makes no sense to me

Prius mileage

The OP mentioned a big difference in the Prius mileage.
There is likely something more sinister at work here. I've heard (from a reliable source) that Toyota is installing new software on any maintenance visit. The reason? The batteries were not lasting as long as projected (and remember, they are warranted for 8 years). So instead of replacing batteries under warranty, Toyota is installing new software that relies less heavily on the batteries..i.e., more time with the gas motor running. 4-5 mpg difference seems to be common. I have not had mine in to the dealer in a while, but when it does go in, I will insist on leaving the software the way it is.
