Hi all,
Apologies that there are existing threads linked to this topic but I wanted to probe what a normal mpg return looks like on UK roads for a gen 3 RX 450h? I got a 2010 with 150k last week and whilst the car is generally very good, I have been a tad disappointed with the mpg. I've not done a long motorway run yet but on some mixed, very careful driving, I'm just about managing 30mpg. With such pronounced effort to be economical, I was hoping for 33mpg. What generally hits mpg hardest in these cars? Can a higher tyre inflation help, e.g. 40 psi? It's got 13 Lexus main dealer service stamps so surely it's well oiled and spark plugs have been changed (i know at least some have from the myLexus app). Ride is a bit choppy and suspect rear bushes have some play but keen to hear people's thoughts. Is 35mpg possible on a long motorway run with controlled speed?
Thanks all...
