It's OK to fill until auto shutoff, and even to top off after that (but not right to the top of the filler neck) if (1) you then drive the car a significant distance and consume enough fuel to bring the level down, or (2) if the outside temperature is cooler or colder than the temperature of the fuel in the supplier's underground tank. If you have the filler handle on automatic and at a high flow rate, the gas will foam up into the filler neck and may shut off the pump when the tank could take up to another gallon. It's OK to top off as long as you don't truly overfill to the point of damaging the fuel and emissions systems. The volume of the fuel compared to the capacity of the tank will decrease significantly as it cools in cold weather and will increase significantly in hot weather. Damage to the emission system is most likely to occur if you would fill the tank to the top, drive a short distance, and then park the vehicle in a hot parking lot for long enough time that the fuel in the tank would heat up and expand. I don't have the full story on the following, but I'll give it the way I rememeber it. I have read that the filling stations are allowed by law to advertise the price of fuel by volume of fuel at a standard temperature, something like 68 deg F. In Canada for most or all of the year the temperature of the fuel in the underground tanks can and will be significantly lower than this and this fuel would be measurably denser than it is at 68 deg F. So if you accurately delivered this fuel by volume the customer would be getting more weight of fuel than agreed upon and in Canada the oil companies have gotten an agreement that they can setup the pumps to give a lesser volume of the cold fuel such that this would be the correct volume at the standard temperature. But in most of the US averaged over the year the temperature of the fuel in the tanks is slightly warmer than the standard temperature and the oil companies have not wanted to make a temperature correction and federal laws on this reflect the wishes of the oil companies. |

It states in the owners manual that you shouldn't top off and to use 93 octane. We have had our Tribeca for 2 years June. We have 60,000 miles on it. Now we either get average 19 mpg or 16 mpg. Depends on who is driving. I was told recently the new Tribeca has a lot of changes. The front is different. They have more horsepower and you can use regular unleaded fuel instead of high octane. Someone asked earlier if there was a difference in performance using high octane. Absolutely. Also, we just had front end work done (clunk) our dealer rented us a new Tribeca. Our car has 60K on it and it is as smooth and tight as the new one. I just purchased Michelin Synchrone Tires for it. I am a very happy Subaru Owner. Even with the first year quirks.

Replying to: morey000 (May 29, 2007 12:34 pm) My biggest complaint is still the very harsh ride I get in the vehicle. Like no other new vehicle I have had in many years. Had the bushings replaced recently for the lower control arms, but that did not seem to improve the situation at all. |

Replying to: occking (May 29, 2007 5:52 pm) anyone with experience on changing tires? The stock Goodyears are not rated all that highly at TireRack. (although they last a long time)
