WJM Posted April 26, 2005 Share Posted April 26, 2005 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? Quote Link to comment Share on other sites More sharing options...
cabron Posted April 27, 2005 Share Posted April 27, 2005 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 Quote Link to comment Share on other sites More sharing options...
Chef Posted April 27, 2005 Share Posted April 27, 2005 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.

ShawnW Posted April 28, 2005 Share Posted April 28, 2005 At least you have the hyd engine. Seem to be better IMO and no valve adjustment necessary. Quote Link to comment Share on other sites More sharing options...
Snowman Posted April 28, 2005 Share Posted April 28, 2005 How old is the oxygen sensor? My mom's 97 OBW was starting to lose MPG b/c of an old sensor. Quote Link to comment Share on other sites More sharing options...
WJM Posted April 28, 2005 Author Share Posted April 28, 2005 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. :-\ Quote Link to comment Share on other sites More sharing options...
Johngenx Posted April 28, 2005 Share Posted April 28, 2005 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. Quote Link to comment Share on other sites More sharing options...
