Lets see...MPGs?

Featured Replies

Wondering what you all have been doing to get more MPG's out of the DOHC Phase 1 EJ25D...Ive got the 1996 Version...so it lacks 10hp/10tq that the 97+ have...no head gasket issues, and its got 191k miles on it.

 

Its BONE stock except for STi Version 8 struts with the stock OB springs.

 

Wondering...intake? Full headerback exhaust?

I have a 01 legacy GT Limited sedan; fully loaded; I get 30 Mpg ( miles per IMPERIAL gallon )

 

 

I use mobil 1 5w-30; no mods; well ( very well ) maintained; car has 124,000Km

Definitely an important distinction to make. I get about 31 imperial MPG on the highway, but only 26 american MPG.

 

e.g. 400 km and 36 l gas.

 

400 km * 0.6214 mile/km = ~249 miles

36 l / 4.54 l/gallon = 7.92 imperial gallons

 

249/7.92 = 31.4 mpg (imperial)

 

or 36 l / 3.75 l/gallon = 9.6 standard gallons

 

250 / 9.6 = 26 mpg (american)

 

Makes a big difference when stating it.

How much less does the RX weigh than the OB? :grin:

3000 something vs 2550 or so... :headbang:

How old is the oxygen sensor? My mom's 97 OBW was starting to lose MPG b/c of an old sensor.

Its about 30k old. Im sure it needs it....$ is a problem to replace it however. :-\

My wife is now leaving her 01 OBW at home most days, "stealing" the Forester. She prefers the seating position and glass area. She has a long gridlocked commute and has been averaging 9.6L/100kms.

 

That's 25USMPG for the metric imparied.
