All,
I have 2001 XC70, T5, 64K miles and I am disappointed with my MPG. I am getting 23 MPG. I just did the 60K maintenance with Volvo plugs, air filter, and cabin filter and I thought I would see some sore of improvement, but alas, no improvement.
I commute about 100+ miles a day and at $3+ a gallon, it is getting pretty expensive. Does anybody have any ideas to improve MPG’s?? I have thought about the K&N filters, I have brand new tires, and they filled according to Volvo specifications. Most of the time my windows are completely shut as I can not stand the road noises or the whistling sounds from partially opened windows.
It’s a 2.4T. I try to use the cruise control as often as possible. I am not an aggressive driver; I do not pound the pedal to get to my desired speed. Again I am looking for hints as I do not believe with the technologies we have today that 23 MPG should be acceptable.
I have limited mechanical skills (I was the mechanic for the 60K maintenance), so please, if you have any hints, please use English phases and not gear-head speak. (LOL)
Thanks,

I get 24 around town with my 2001 T5, (5 speed manual). If I baby it, I can get 27 around town, but this is putting in neutral down hills etc. Highway, I consistently get 28. Now, if they would only bring in the friggin diesel here. The D5 in Europe consistently gets 50 MPG and has more torque than my T5!!!!!!!!

Wow! 23 mpg with an XC! That's pretty good. Now, on long trips I have noticed that my XC can get upwards of 28 mpg. But like Klaus said it's about your terrain. Most of that driving was done on mostly flat ground with the tires pumped to 39 psi. If you haven't already done so, go to stretcher.com for some good tips to follow for gas mileage. You may have done these but I'd sure try 'em all. I'd also suggest to play around with different octane levels too.

My MPG has averaged 23.4 MPG and 23.7 MPG over the last 167,000 miles and my car has less frontal area, weighs a couple hundred pounds less and has a stick shift.
236 horses will eat some hay, even if they're small horses.
BTW, I thought all the T5s were 2.3L not 2.4L???

I'm sorry but I have to differ. I do not believe that horsepower should be considered the driving factor when determining MPG.
Besides the 2000 XC70 AWD/SE, we have a 1998 BMW E36 M3 four-door sedan (3.2L I6, 24V, manual, 240 hp (SAE) at 6,000 rpm). I drive 40 miles a day on city/highway (mostly highway). My average speed is 45 MPH and I get 28.5-30.2 MPG consistently. I realize the BMW is somewhat lighter (3175 lbs), and the automatic AWD definitely reduces the MPG.
When we purchased the XC last month we drove it home from FL to VA, around 830 miles. We averaged 66 MPH, 26 MPG. Granted this was before new tires and TLC.
I just think the MPG should be better in these newer Volvos!

BTC,
There is no such thing as an XC with a T5. I think what he was trying to imply that he has a low pressure turbo 2.4L which has the boost turned on whenever he hits an uphill grade of any kind. And CT is quite hilly, except for the coast line next to I95. And the traffic is terrible!

Check the brakes, even slightly binding brakes affects mpg.
Remove the pads and clean all contact surfaces from rust and dirt, remove the anti-squeal rubber if they are starting to break up. This gives a more distinct return. "Energy"-tires seems to have a positive effect but i guess it is less than advertised, hard to tell :)

Have you tried different gas brands? Are you using the specified high test?
The gasahol which many places must sell, gives lower mileage than the old mix.

Pump all four tires up to 38lbs. In the 15 years that I lived in CT, I have found the cruise control worthless. There was too much traffic. Besides, CC does not equate good milage, the CC in hilly terrain is actually worse for milage because of the inability to give it gas before the hill starts and to allow the car to slow 5mph at the crest of the hill. Here in the flat midwest, CC is a Godsend. It keeps us from going too fast because the mailboxes are 1/2 mile apart.
Actually, studies have shown that 3/4 to 7/8 throttle to attain speed is better on gas milage than 1/2 or 1/4 throttle to achieve the same speed. The bid deal is to let of of the gas the second you realize you will eventually have to slow down.
The AC is costing you 1mpg when the compressor is engaged.

I'm reminded of research BMW did about 25 years ago, where they found that fuel economy in city driving was maximized by using 3/4 (or so) throttle, but upshifting at only 2000 rpm. This sounds strange, but it can be done smoothly with a fairly torquey engine (like a Volvo 5 cylinder) and a manual transmission.
We know that engine efficiency (work performed vs. fuel consumed) is maximized at something fairly close to wide open throttle. The challenge is understanding what works best with each car. For example, does this apply to turbos in the same way as n/a engines? Also, in automatic-equipped cars without Geartronic, can a driver readily force an early upshift by lifting the throttle?
The BMW 528e was designed to take full advantage of this knowledge, and had a special low hp, high torque engine with a 4700 rpm redline. However, it disappeared after a few years. I'd guess that 90% of the owners had no clue about how it was designed to be driven.
