Mine should click to 250K today
Heading to Brisbane and the car is strong and tight as any.
intending to do a petrol lit/100Km test by filling before and after the trip. I have just switched to Conti cross contact uhp at 255 60 R18 over previous tyre on car when I bought it which were 255 55 R18 -
I would expect to use less fuel than usual (as the revolutions are higher with smaller profile tyre) but also have to consider it takes more power to push with greater circumference which may play a part.
I have done the same trip and clocked 10.2 lits/100km - I am doing exactly the same trip with same load to see if there is a difference and which tyre profile is more economical.
As far as Logs show - no engine issues to date. Has had things like Aircon compressor , AES Compressor, and usual brake and suspension repairs done .. not much done during the last two years with me. only standard servicing an Alternator and a few electronic repairs by the British offroad team.
Engine strong as new - I feel sure it will double the current Km's without a problem with regular servicing but who can really foretell.
There would be plenty out there who must be approaching half a mill I would think as they are such a great workhorse.
