    I inflated tires on Gen3 as high as 46psi on aftermarket tires with 51psi max cold pressure rating in the hope to improve the fuel efficiency. I also tried on my PRIME on OEM tires as well. But in the end, I did not find noticeable differences in everyday mpg.

    I now try to pump mine at 38 psi cold all around on my PRIME. But honestly, as long as they are slightly above 36psi I don't care much. When I pump and adjust tire pressure, as soon as I remove the inflator, they are slightly different anyway. Plus, in my climate, cold tire pressure in a morning is almost 4 psi lower than afternoon cold tire pressure just from ambient temperature differences.

    It’s been unseasonably hot in London, UK, for the past week or two. It’s reflected in my last fill up.

    Here’s me breaking my own MPG record on my 2nd Gen 2008 Prius Tspirit.

    I could probably get to 250 miles on my last bar of fuel, but that would be “fuelish” of me, so I won’t - I’ll refuel tomorrow morning.

    I didn’t think this was possible in a 12 year old Toyota Hybrid...!!!!

    That's amazing! Our Gen 2 had a rubber bladder so there was no way I can come even close to that. IIRC, the best I could do is in the neighbourhood of 700 kilometres.
