Recent MPG on a road trip

Recommended Posts

Hi All,

Just posting my recent MPG of 49 MPG on my IS F Sport on a recent trip to Inverness, Scotland from London and I am amazed. 
A mix of 55- 75 mph on the road.

Very nice. Although also calculate when refuelling. Easy if full-to-full, or you can use an app for fractional fills. The computer in mine (2015 Advance, 17'' rubber) is probably 2 MPG over, or about 4.5% better than calculating based on trip odo and pump (my rule is that I stop when the pump clicks off). If you're interested, of course, no need to geek it out.

Thanks, On checking the correct mpg is around 47 and yes the on board computer is about 2 digits higher.

I got around 54 mpg on a non stop run Crewe to St Albans on lockdown roads, I didn't stop anywhere and kept the speedo at an indicated 75 mph. 


That's impressive. I never thought that I would be overly concerned about MPG figures, since I came from an IS220D which was dismal, at best.

If I was lucky I got 27mpg around town and never improved on 37mpg on a long run. 

So, not thinking I would care, i am shocked that I do.

I am always in ECO mode and I'm constantly watching the damn gauge and always try to improve on my last personal best. (42.9 combined)

I find it annoying that I have become "That Person"! 

Anyway, as it has had an adverse effect on my driving, I now refuse to plug in my smart meter monitor, in fear I will turn off things in the house that shouldn't be turned off,  like the fish tank!

I used to like driving fast and pushing my traction boundaries, damn these gauges. lol
