05 Jag XK8 low mpg with CAI and Mina Exhaust?
Hi fellas,
Maybe it's just me ...tell me I am wrong.
I installed Mina's open air intake and cat back full exhaust about 2 months ago....however, it seems that my MPG got worse, is this possible?
I though these mods should help mpg? maybe it is because of winter time? (35-40 degree wet weather) here in portland ...yuuck.
I bought the car March 2015... I can easily get 25-26 mpg pure hwy driving cruising at 90mph...city mpg was around 18.5 ...and 17 at worse.
after the installs... i am only getting 22-23 pure hwy driving and last week I got 15.5 mpg pure city driving. My average is down to 18-19 mpg mixed.... I have 46K on the odo now...maybe time for spark plugs?
ideas?

Your summer fuel use and winter use seems right in line with what I get. Could be fuel. https://blog.gasbuddy.com/posts/Wint...22955-413.aspx
