This is the $30 block heater:
http://www.subarugenuineparts.com/pr...e80886011f0e1d The plug comes very close to the exhaust manifold, and if you don't orient it correctly, it will touch. The $100 heater has an angled connector, so it doesn't have this problem.

When I called the dealer the price would be $204 + the heater (~$100). I didn't ask if that included replacement coolant; you have to drain the coolant to install it. I know often shop supplies like this aren't included in the quote. I've been meaning to call and ask but haven't.
On the other hand, the install guide for the block heater says it's a 20 minute install, so based on that, and the price of labor, I would think the coolant refill would be included. |

Regarding the A/C going on with defrost, I had the A/C go on automatically when I had the left and right dials on "Auto" and set my temperature on the colder settings. I have the Limited trim level. Probably covered in the manual!

With regards to adding a block heater and any other type of heater, you should incorporate the costs of the hardware/install and also the cost of electricity it takes to heat. Heating elements are rarely efficient and draw a decent amount of current. I don't think it's worth the cost to possibly save a small amount of gas.

my MPGs recently took a good dive. I went from average around 26-27 MPG doing short trips (reasonable considering) to averaging 23-24 MPG. I'm not sure if the gas just changed over to the winter mix or what.

I know this sounds crazy but i think my car gets better gas mileage with a full tank vs 1/5 tank or less. Any possible reasoning behind this?

If you fill when the tank is half empty, then will it be 5/6/7% ethanol or something slightly higher or lower? E0 is E0, E1 is E1, and E5 is E5. If you are measuring E0 against E10, one would assume that the proper mix is being evaluated and not some other unknown ratio.

[quote=stevehnm;38960188]Here's another one, magnetic - you just put it on your oil pan:
[url="[/quote] Would you recommend something like that? I certainly don't have the tools or skills to install the freeze plug heater from subaru. Edit: don't even bother asking why my quote is messed up. one of my chrome extensions is a neonazi or something. |

The heater draws 400 watts, so if you run it for two hours and pay $0.14/kwh, it will cost you 11.2 cents. Compared to just climbing into a frozen car, starting the engine and taking off, that 11 cents is about what you'd save in fuel, so it's a wash in that case. However, if the block heater saves you from remote starting or idling to warm up, the savings would be greater. There are other benefits too: -Less startup wear ($$$$) -More cabin heat sooner -Better driveability |

Dear Tom and Ray: While I know I should be worrying about the tension in Kosovo, I am instead trying to figure out the answer to a dumb question. Why do I get many more miles out of the first half of my tank of gas than out of the second half? For example, my car gets about 200 miles out of the first half-tank of gas. You would think, then, that I would get 400 miles from a full tank. But I don't. I get only another 100 miles or so as the needle goes from half-full to empty. This has been true of other cars I've owned, too. Why is this? -- Frank Ray: You're absolutely right, Frank. It IS true of every car I've ever owned, too. Tom: I can't say whether or not my '63 Dodge Dart ever did this. I never filled it up all the way because I didn't want to invest more money in the car than it's worth. Ray: Here's what's going on: Even after your gauge reads "Full," the tank itself is not necessarily completely filled up. You can always cram in an extra gallon or two. Sometimes more. So you've got gas at the top end of the tank that the gauge doesn't even see. Tom: So right away, you're starting with a couple of "bonus" gallons at the top. Then, you get "cheated" out of a couple of gallons at the bottom end of the tank, because even when the gauge reads "Empty," there's still more gas in there. And the amount varies tremendously from car to car. Ray: Here's how it may work using hypothetical numbers. Let's say the actual capacity of your gas tank is 20 gallons. The gauge may only show you what's between the 18 gallon mark (Full) and the 2 gallon mark (Empty). The gauge would read "half-full" when you had 9 gallons left. Tom: So after you've "filled it up," you have to burn off 2 gallons of fuel before the needle even starts to move down from the "full" mark. That means you actually DO go farther on the first half of your tank-full. And by the time you've gotten down to the halfway point (from 20 gallons down to nine), you've had the benefit of 11 gallons of gas. Ray: Whereas, in the second half, you only get 7 gallons before the gauge reads empty (from nine down to two). And that's only if you run it all the way down to empty, which most people don't. Tom: Why do most manufacturers make their gauges like this? It's not that they can't make them more accurate. It's just that they don't want you to overfill the tank or run out of gas. Ray: Overfilling the tank can ruin the charcoal canister that traps fuel vapors. It's part of the emissions system and is therefore the manufacturer's responsibility for the first 100,000 miles. Tom: And they don't want you to run out of gas for two reasons. One is that, as we all know, they are great humanitarians and don't want you to have to walk home on a cold, dark, rainy night. But more importantly, the car's fuel pump lives in the gas tank and is cooled by the gasoline. And they'd feel just terrible if you ran out of gas and burned out the fuel pump -- especially while the car was covered by THEIR warranty. |

Well, you have one answer, but there is also another very simple answer. Think of a perfect cube. Now notch it out in the middle from one side to the other so it is like a saddle. You sit that over the rear control arms and suspension. You have the total volume of said cube at the top until you reach the point that the tank is notched to fit over "stuff". There is simply less volume in the lower part of the tank as a result of the notch. I don't know how many cars are designed this way, but I recall that on my old WRX, ther was actually a secondary fuel pump inside the tank to keep the level equalized in the lower part. Otherwise there would be fuel in one section you couldn't get to for use. Same principal if you had a pyramid. For every inch drop inside, the volume increases. A tank shaped like that would go down quickly at the top and slowly at the bottom. A fuel level indicator is a simple device. Generally, it does not meter fuel flow. It simply tells you the level inside the tank. Nothing more than a bobber floating on the surface connected to a rheostat. John Last edited by Guzzi 1; 01-21-2013 at 04:58 PM. |

well, i have to admit: i learned something new. mine has been set that way for the past few months and my mileage has really dropped in that time. i'll have to play around with this as i unlikely need it on all the time.

its easier to keep 40+ mpg while cruising with a full tank. Despite the extra weight. Im not talking about overall miles. |

Maybe a near empty tank allows for more moisture to condense, which is absorbed by the ethanol.
