Winter Gas

OMG! what has winter gas done to my car! my MPG is so bad now. i lost about 170km on the last tank of gas and about the same on the tank before. the extra idle time to warm the car up doesnt help but it shouldnt make that much of a difference.

does anyone know how to limit the effects on winter gas towards ur mpg? and what is it about winter gas that does this?

i was thinking about disconnecting my battery for a few mins and try to re teach the computer. would that help at all? i cannot do all winter with these shitty results.

Check your owner's manual... you don't need to let the car idle, just start her up, and don't drive too rough while the "Cool" engine temperature light is on.

That should save you some gas.



Other than that, my mileage was a little bit worse in the winter. Good luck!

It's more than the gas. Gear and transmission oil takes time to warm up. If the weather is bad, traffic is worse.

Essentially, they add a gas line antifreeze (99% isopropl alcohol (sp?) perhaps) to the fuel. This is similar to the additive you can buy at gas bars, auto parts suppliers or for a one-tenth of the price at the pharmacy.
NOTE: Big Gas talks like they're doing you a favour by providing winter gas but I'm sure the increased fuel sold due to our decrease in fuel efficiency makes it a very profitable favour.

Yeah normally I get around 510km out of a tank but now I'm getting barely 450 ... more like 430. Sucks but that's what you get for living in a cold climate :P

When the air is cooler, the air is more dense.
When it is more dense, it has a higher 02 content.
A higher 02 content means the ECU meeters more fuel.

Why do you think a CAI can give a bit more power? It's called a COLD AIR intake.

You are going to burn a bit more gas in the winter and it has little to do with any so-called winter gas.

99% isopropl alcohol --- wouldn't that make the gasoline less basic?

Is there any way to reverse some of the effects of winter gas, by using some type of additive?
