Does anyone know why my 08 tl says fuel range is 460 miles when I fill it, but while driving the gauge drops significantly and I basically get 300-330 a tank. I'm confused. Acura lies to me lol, anyone have a solution thanks

 

Is this normal for the tank to drop two lines only going 4o miles ?

 

you realize that the driving range estimate is based on if you maintained the average mpg shown on your MID? If you took a break and stopped your car for any reason, you already deviated from the estimation.

reset the MID when you fill up, and see your average mpg at the end of the tank, it will match the amount of miles you actually drove.

anyways all these are just numbers, if you're satisfied with the amount of gas your car uses, why bother with these kinds of threads? it doesnt matter how much the bar drops for a certain amount of miles. it could drop the whole way after driving for 100 mile for all I care, but if Im getting the mpg i should be getting i wont complain

 

lol at why is the range dropping when i drive?

 

It takes about 40 miles for mine to come down to the full mark. I've gotten 100 miles before coming down to the full mark when I topped off but that's not recommended. If your pump shuts off exactly at the full mark and those 40 miles are mostly city, it can easily come down a couple ticks in that distance.

 

I drive my MT in pretty heavy traffic to and from work and drive about 300 miles a week. Each week I've had the car, I've added about 13 gallons (that's where the fuel light comes on). That's about 23 mpg. The specs say it's a 17 gallon tank, so I should have another 80ish miles left after the light comes on.

I recommend using one of the trip odometers to keep track so you have an idea of how much fuel your using between fill ups.

 

I took a roadtrip from NorCal to SoCal a few weeks ago and I got exactly 400 miles per tank each way. Your range depends on your driving habits, same rules apply for ANY car...

 

Like just about everything, things vary based on usage.

I have a short commute, and on a very cold day with the car sitting outside overnight without block heater use, I average 13-15 MPG. On a hot day with a block heater, I can get 38-42 on the exact same commute with the exact same car and driver. Driving recklessly and accelerating into red lights would of course drop these numbers. They can go up with ideal driving as well.

The fuel gauge goes down when you use gas. Use it faster, and it goes down faster. The car can't predict the future, its an estimation. Your numbers sound totally reasonable.

 

That's very interesting about the difference from a cold start to a wam start. We all know it makes a difference but that's huge. I guess it easily pays for the electricity consumed. My drive is 1.3 miles to work and 1.5 miles home. I average 13mpg as long as I drive it nice and what choice do I have when the oil is barely warm by the time I get to where I'm going.

Mine sits in a small 2 car garage and with both cars parked inside in the winter the coldest it gets by 4:45am is about 58 degrees on the coldest winter days. How cold is cold in your area?


I've considered a block or an oil pan heater. The oil heater wouldn't do as much for mileage. Is yours one that installs in a freeze plug?

 

I have the factory freeze plug heater purchased right from Honda. In a garage it heats the oil as well, just slowly. I find it starts to make no difference past about 3-4 hours, its on a timer to start 3.5 hours before I leave in the morning. Oil is usually about 90-100 at startup, coolant 135-145.

In the peak of winter, 20-30ºF is common during the daytime. Late night and early morning, its not out of the question to break into negatives. Rev hang is brutal with a super cold engine. The block heater means the car starts off 'warm', and is ready for full throttle in a few minutes. Presumably the cold 'drivability' would be better with an auto, assuming the shift quality is acceptable with a cold trans.

The car drives a whole lot nicer once everything is up to temp, so its disappointing that this tends to happen right when I get home. In a garage, with a block heater on 3+ hours, everything under the bay is warmed up and the car drives nice right out of the garage. P/S fluid is one thing that never really comes up to temp fully on a very cold day and the steering can transit much more engine vibrations. The block heater helps that a whole lot, even though it does not directly heat it. If you're parked outside, the little 400W freeze plug heater won't make a huge impact, but it is noticeable. In a cold garage, its night and day. I would imagine one of those 1500W recalculating heaters that you need to chop into the hoses would make a big impact outdoors. Running that several hours a day, every day, would start to make a dent in your electric bill.
