Well, the trip has set a new record, but not by as much as I'd hoped for.
I ended up at 4.49 L/100km or 52.3 mpg while the car's FE indicator was showing a solid 4.0 L/100km or 58.8 mpg for the last 100 miles.
That's double its usual error.
Around 107 miles were done on the old wheels and tyres @ 3 bar / 43.5 psi.
The remaining 440 miles were on Volvo (DRIVe) Libra 16" rims and new Michelin Energy Saver tyres with unknown pressure (probably 36psi)
They will be inflated to 43.5 psi when cold.
The old rims and tyres went in the boot - a lot of weight !
I've also picked up a used 5th rim that'll serve as a full-size spare on longer trips - adding even more weight.
In Germany, you need a
Feinstaubplakette to get into the Umweltzones (vehicle emission control zones), so I got me a green sticker while I was near a TÜV test facility.
