No bull about it sir
Cruise control was stuck on at 80mph, only went down to 65ish once for about 2 miles
93miles of motorway, 6 miles of 50mph dual carriageway and about 1 mile of 30mph to get me home
When I'm doing 70 on a long run I get about 29-30mpg.
All about how you drive and what the rest of the traffic is doing
I didn't touch the brake apart from once on the motorway, meaning the car was doing little/no work to keep me at cruise speed
I've reset the avg MPG computer when doing 50mph in average speedworks before and after 10miles it showed me 36MPG
Maybe I should reset the computer and let it get a new mpg count. I don't do any motorway driving in my Z so that maybe why?
If you dont do any motorway miles then you'll get nowhere near that all about keeping a constant speed, looking ahead so you don't need to brake and accelerate all the time and just keeping the car moving with the minimum amount of effort
