has now got me stuffed. My tank is 18lt capacity a few weeks ago, I got 350k's on tank full without going to reserve, the fill took 17lts, I thought this a bit weird, but anyway. Then on my way to Curry last Wednesday, I was at 310k and it konked out, went to reserve, no probs. Over the weekend I went to Dinner Plain. I filled at 240k's, then at 300k's and again at 200k's. No reserve required throughout this at all. Last night I went to coffee etc and then rode into work this morning, I konked out at Toorak Rd Exit with 230 on the trip metre. Again over to reserve and off I went. Obviously will fill up on way home this evening. Throughout that I have used normal unleaded, Premium Unleaded (98RON) and Mobil's Premium unleaded at 96RON. It was the 96 that got me the 300k's last time. Any ideas on what might explain this wild variation ?
