To improve your mpg, try driving with an imaginary raw egg under your right foot.

'07 XK base NA 82Kmi
24-26 on the highway, but only 10-12 in the city. Bit of a leadfoot, but I'd still think I could get 17-18.
MAF cleaned, O2 sensors read alright (but are original), Lambda at stoichiometry, LTFT at 0%, 2 yr old gas filter and fuel pump (fuel pressure on spec in mid-50's psi). No cat codes, etc. 0-20 oil; tire pressure to spec, Chevron 91 with Techron, plus additional bottle of techron every 6 months. All seems well, but the mpg seems lower than it should at lower speeds.
Considering a SDD reset-relearn of the ZF to see if that helps. Other Ideas?
Thanks

I feel pretty confident that had I set cruise to 75 I would have achieved at least 23mpg but that isn’t in my dna. I’ll watch this for a while as I’m curious as to how much affect and occasional jaunt into S mode has on the miles per gallon. When I get a chance I’ll probably replace fuel filter and air filters but I’m not concerned at this point in time.

wymjym, 2009 XKR, 42K, new air filters, repaired vacuum lines ( long story), oil & filter, fresh tank high octane, 80 mile trip home from shop at speeds averaging 70 or so. Jim, my trip gauge showed 15 mpg, but I'm in denial. Like CeeJay, I don't really care too much about fuel economy. I genuinely enjoy, however, just sitting in my garage admiring the lines of the XKR. Hey, beats watching CNN! Also Jim, today I decided to remove all of the wheels and clean/polish the inside of the wheels. Those have got to be the absolute heaviest wheels I've ever handled!! I guess I need to double up on my vitamin supplements?!

OEM Toyota 80 series 16x8 wheels are around 25 pounds + 4 lbs. of dynabeads + 70ish pounds of rubber = makes the 19" XKR rear wheel/tire feel like it's made out of carbon fiber and unicorn farts.
