Hi: Quick trip to the Berkshires this weekend in my '05 TL auto. 325 miles RT, 80/20% Highway/local roads. Per OBC:
 
Average MPH: 60
Average MPG: 28
 
Whilst on the Mass Pike and 495, cruised mostly 80mph with bursts slightly higher and some traffic lowered into the 60s.

You were able to hold an average speed of 60 on 495 on a weekend?!?
 
The westbound pike in Auburn was an absolute parking lot yesterday.

80 mph on the Mass Pike? That's kind of slow from what I remember.

80 is slow on the pike, unless it's 6:30-9 am or 4:30-7pm.
 
Then, every meathead in the world gets on the road and then slams on their brakes as soon as they see that weird glowing orb in the sky.
 
It's a sun people, buy some glasses!
 
Ugh.

Yeah, I saw the Westbound tie-up as I cruised home Eastbound. Actually, my average speed on 495/MassPike I'm sure was in the high 70s, maybe low 80s. But a bit of local driving in the Berkshires brought the average down. The left lane of the Pike was generally 80mph-ish.
 
I was passed by a black 'Slade on 495s Sunday. I was at 80, he was doing at least 100. Late for the Pats game, I guess... And he wasn't getting 28mpg (and probably didn't care)!

Got it on a 5 mile stretch of Garden state parkway in NJ, after filling up and going right on highway in moderate traffic that kept my speed at a constand 50-55mph.

Just did a first long trip for 06TL auto of 430 miles. Overall 30-31 MPG on highway average 70mph w/ AC on. Mostly city driving in town since ownership around 21 MPG. So far so good.

I also just completed a longish trip--in my 2008TL. It was 98% freeway, and I really babied it, doing 62-65 MPH most of the time. Part of the trip was rather hilly, though. My trip computer gave me a MPG of about 31.4. I know this because it was switching back and forth between 31 and 32 toward the end of the trip until finally settling at 31. Not really believing the trip computer's accuracy, I did a very careful measurement of actual MPG, dividing miles traveled by gallons used. The result was 29.0 MPG--about 8% lower than indicated by the trip computer.
 
That result--8% off--accords with my less precise measurements done around town, where the trip computer usually read around 20 to maybe 21 MPG, and my calculations come in at 19.
 
I am not really very happy with these figures, but they are pretty close to the EPA estimates of 18 and 26. I suspect with more normal driving, my trip mileage would be down 1 or 2, to around 27 or 28.

Message #241 provides very useful information. The only way to figure mpg is with a pencil & paper (actual miles driven divided by actual gallons used). Anything else is a guess resulting in totally useless information.

I've checked the mileage on the first three tanks of gas and the computer showed 2 MPG better than the actual calculation on each of the three tanks. This made me wonder if a lot of the MPG reported here are what the computer reports or actual calculation.
