H6 3.0 milage

[Don Truitt]

I am new to the Subaru family as I recently bought a new Outback (U.S.)
with
the H6
3.0 engine. I have about 2300 miles on it. It is a great car so far.

However, I was wondering if the gas milage will improve over time. I am

getting about 18.5 in mixed driving and @17 "city". The highest I have
gotten on mostly highway driving with 4 people in the car is about 22.3.

Anybody have any experience with this engine? Is there anything I
should be
especially on the look out for?

Thanks in advance for any information you can give me. Please respond
to the newsgroup.

I forget how big the tank is but I average about 300miles per tank with my
H6. I haven't noticed to much
difference between city and highway. I'm guessing this is because of the
way the EPA calculates city driving
something like 23 stops and xx min idle per mile. I make maybe 2 to 3 stops
per 5 miles.

If you want a little more mpg google this group for skeezyweezy's (sic)
post on how to put the muffler bypass spring
into always open. I saw a couple mpg jump when I did mine with no other
problems.

I have an '01 VDC, with 55K miles.
I do 90% highway driving at 75-80 MPH.

Average is 24 MPG.
Always.

I have a 2003 Outback wagon with the H6-3.0 engine and automatic
transmission. Mine has 2800 miles on it. My mileage on the last 3
tanks of gas has been between 24 and 26 mpg. That's U.S. gallons,
premium-grade fuel (93 octane). According to the fuel pumps around
here, that octane rating uses the formula (R+M)/2. The miles I've
driven have been a mix of rural, small town, and freeway, but mostly
rural, at speeds between 45 and 65 mph.

According to the EPA, the best fuel economy is found at speeds around
45-55 mph. http://www.fueleconomy.gov/feg/driveHabits.shtml

Maybe that's why my mileage is pretty good?

My '71 XKE gets its best mileage at 3000 RPM, and that translates to
between 65-70 mph. It's about 21.5 mpg at that rate.
