filumuko Posted July 29, 2020 Share Posted July 29, 2020 (edited) Hello all, new to Subaru’s but I’ve owned and maintained many vehicles. I recently purchased a 2003 Subaru Forester 2.5X as my beater daily for work. 100,000miles on the engine. The whole reason I bought it was because I needed something with decent space and decent MPG, and the previous owner (I know, can’t be trusted but still) claimed he got around 300 miles on a full tank. After driving it for a whopping 70 miles I’m now reading a half tank. I realize they’re AWD and don’t get amazing gas mileage, I’ve owned other AWD vehicles, but at this rate I know something has to be wrong. I don’t smell any fuel leaks, but I haven’t ruled that out either. Any help/recommendations regarding the situation or what could be wrong would be greatly appreciated. Overall the car runs great super smooth thats why I’m stumped. I’ve never seen a literal 50% decrease in gas mileage in anything I’ve owned. p.s. codswallop these cars. let's go watch the best pornooo https://bestfreepornsites.pro Edited September 18, 2020 by filumuko Quote Link to comment Share on other sites More sharing options...
ronemus Posted July 29, 2020 Share Posted July 29, 2020 Could be a bad oxygen sensor, which in turn makes the car run rich and reduces mileage. Exhaust gas analysis will instantly tell whether this is the case, although getting the test run will probably cost at least a much as replacement sensor; if you're a DIY type you'll be ahead if you just replace it. I'm assuming you've checked for leaks and haven't been driving like a maniac or idling for hours. You should be able to get 400 miles on a full tank on the highway, even at 65-70 mph.

Stevo F Posted July 29, 2020 Share Posted July 29, 2020 Don't go by the gas gauge alone. I would calculate the MPG's after a couple of tanks of gas. My 2003 Forester will get 20- 22MPG in around town driving and 24- 25 MPG on the highway, so yours should get at least 20 MPG or higher depending on the type of driving. 1 Quote Link to comment Share on other sites More sharing options...
heartless Posted July 29, 2020 Share Posted July 29, 2020 (edited) i have a 2002 Forester, and typically get around 26-27 mpg average.. 250-300miles per tank, depending on how low I let it get. as others have said, do not go by the gauge alone.. gauges can do weird things.

1 Lucky Texan Posted July 30, 2020 Share Posted July 30, 2020 how's the power? Knock sensors have failed, not set a CEL, but killed performance. Quote Link to comment Share on other sites More sharing options...
