comment Overheating & coolant loss in 1998 Subaru Outback
Amended my answer to recommend a coolant flush as the next step: it still sounds like "stop leak" is clogging your flow.

comment do all quattros have shafts connecting front and rear axles
You can decode your VIN by referring to the codes in the owners manual. You can also use some web services like the following: audivindecoder.com/vins/waudk78t59a020347

@Mauro, actually if you have the VIN and the owner's manual, you can usually decode it yourself.

comment Which color headlight is the safest?
How would you measure the safety of bulb color? Are you trying to allow for male colorblindness? en.wikipedia.org/wiki/Color_blindness#Classification Without a "safest" metric, this is a "what's your favorite color?" question which is directly addressed in the FAQ: mechanics.stackexchange.com/faq#dontask

Could you post a picture of what you're seeing? We would certainly expect to see a driveshaft running to the aft end of the car: fotos.autozeitung.de/1024x768/images/bildergalerie/2009/06/…

comment Use of Neutral Gear in Automatic Transmission
@Jesse, yes, you're correct. At the same time, so is Rory. If you're shifting to park, you're almost certainly motionless (or about to learn a valuable lesson). So you're going to shift from D to N to R to P.

comment What are the benefits of premium (high octane) petrol?
What's missing from your remark about "power adder"s is why they require higher octane. In the next bullet, you imply that any additional power will require higher octane. That isn't the case: a better intake and exhaust on NA cars will often improve power without impact on octane requirements. As written, this answer is incomplete, bordering on incorrect.

comment What are the benefits of premium (high octane) petrol?
"But due to the power adder they will require a higher octane": this is a specific place where compression and temperature are both important. The compression ratio on the Fiat Abarth is apparently 9.8:1 (higher than my old Mustang V8) with a peak boost of 18.1 psi. That means that without boost, the car should be able to handle regular gas. As higher temperature boost is added, low octane gas will become problematic quickly.

This answer is also missing discussion of temperature which is just as bad as compression in an ideal gas law sense.

For slack cable, might want to point out that max acceleration will be WAY down.

@theUg, I'd rather let other members of the community make that assessment. We have quite a few active users now: what do you guys think?

Welcome to the site! It is not clear from this question what mechanical problem you are trying to solve.

comment Why does my gas not fill all the way?
Yes - could confirm that it's a bad reading by checking mileage. Is the OP still getting a full tank's worth of driving range?

comment Does accelerating faster worsen fuel efficiency?
BSFC gives you information about your engine at a steady state, not during acceleration at different throttle positions with varying tuning parameters. Fuel consumption is easily measured using the OBD II port. Rabbit starts are less efficient than gradual acceleration.

comment What happens if I drive without antifreeze in my car?
Clarifying the "empty": was the entire system empty or just the overflow tank? There's a lot more coolant in the system (normally) than is found in the white plastic expansion tank. Did you remove the radiator cap and check to see if it were bone dry? Said another way, how much fluid did you have to put in to fill it back up? If it wasn't more than five quarts / liters, then it wasn't empty.

comment What happens if I drive without antifreeze in my car?
To clarify, were you low on coolant or at zero coolant? Those are two totally different situations. The first is potentially a don't care in the middle of winter, the second is potentially fatal for the vehicle.
