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.
