So I bought a nice, 2008 Sportage LX, with the standard SUV bells and whistles. With a small 2.0l engine, I anticipated highway MPG of at LEAST in the low 30 mpg. I'm incredibly.disappointed to learn that, at best, it looks like the high 20's is what I can anticipate. This is after switching to 5W20 full synthetic oil, changing the spark plugs (iridium), plug wires, air filter, insuring tires are properly inflated, etc.. Dealer tells me what Im.getting is typical and it's down to ECU programming, for which nothing can be done. My Mazda Tribute, also loaded and with a 1.7l engine, got at least 10 mpg MORE! What say you?
