I have mine for 4 years now the biggest thing that rub the mpg and hp is 10w40 oil you have to have 5w30 then change your air filter and put k&n and take your EGR out clean it or change it if you have more than 100k it,s costly about 78$ or just take it out clean with brush new gasket and you should be ok.I,m delivering pizza and i,m really hard on eng ,still get 30 to 33 in townand never got 45 mpgmake sure your brake are not grabbing or you e brake are not engaged or adjusted tightly,it,s only 3 cyl and less 1000 cc,any little thing can cause low gas millage
