Pre-mixed Fuel

[BOGWHEEL]

Have been using Mineral 2T with standard unleaded in my bikes for yonks.
Now having a modern 2T enduro (which uses synthetic 2T with 98 Ron unleaded @ 50:1), i was wondering what others are using in thier machines.
Have put the latter fuel in my sherpa, but have only ridden around the paddock, and it seemed ok. Would be nice to have just one lot of fuel.

I've run my 198 b on 98 ron with 50% Semi Synth for as long as I can remember with no problems, the key thing is to use fresh petrol, the shelf life of 98 ron is about two weeks at the servo and two weeks in your can, after that it looses its octane quite quickly.

hope this helps

Like Paul I also use semi-synthetic in my twinshocks rather than full synthetic.
I do it that way because semi protects the bearings from corrosion better than full synthetic, and produces less carbon buildup than straight mineral oil. If you ride the sherpa (or the whizz-bang modern enduro bike) frequently, it wont make a difference, but if a bike sits for months between rides, it would be safer to use semi-synthetic.
If your petrol is supplied from the Brisbane refineries, you will probably find that BP Ultimate works better in your bikes and lasts longer stored than the Caltex refinery supplied equivalent. I'm not saying that is the case for BP and Caltex fuel supplied from other refineries because I haven't tried them.

The other trick is to buy from a servo with a BIG throughput. Sadly the little guy in town is likely to have had his 98 sitting around, the Freeway servo probably gets restocked a couple of times a week and even plodders like me can spot a noticable difference in pick up off a closed throttle between fresh fuel and stale fuel.
