    Has anyone else be using Mobil's Synergy 8000.. the 97.5 Octane fuel with 3% Ethonal in it??They say that you may need to check if your bike can take it, age seems to have alot to do with it.. haven't had any comments as Euro bikes don't have issues running the stuff.I've been doing a few k's between Welly's and Waiouru over the past month and have found the bike seems to run very well. A little better on fuel as well, approx 300k's on 15 ltrs.. and above all the cost is the same as 95. I wounder if BP have looked at this yet??Dave 😆

    I've used it. I normally fill up with BP, it's on the way to work. We've got a Mobil Station more or less across the road, so I sometimes fill up there. Bike seems to ping with whatever I put in there. On day this thing will blow up on me.

    Hi,I have used the Gull 98 octane with ethanol in it in both my car and my bike. My car seems to run smoother with it, but I am unsure if I notice a difference with my bike, but it certainly did not give any problems or adverse effects.Cheers,Mike

    I know this is a BMW site but I have a 2000 996 Ducati which runs on unleaded petrol (Ex SA Bike). Speaking to Ducati in Auckland, they say that I can run the bike on 96 unleaded. Does any-one know if this is true as it will be very costly if not

    If they say it runs on unleaded, I am sure you can run it on 96 unleaded. Did you run it with 98 unleaded before?

    My understanding of lead in fuel was that it was a cheap way to boost the octane rating. It also served as a lubricant for the valves. However with the advent of modern technology (I think thats how to spell that word) the valve seats and faces are far superior to the days of a valve grind every 30000 mls  😮 Also oils etc have all improved. I know that when LPG and CNG first came to NZ the same arguements and issues arose. The falcon 4.1 engines valves dissapeared so far into the head the auto adjusters gave up!!However as stated these issues dont exist with modern engines (much) However new issues arise with Fuel injection systems with gum forming (thats a nice word for shit) and "o" rings perishing or deforming as a result of incompatibilty with fuel additives.A rule of thumb I live byIf it was any good the Manufacturer would add it in the first place  😀If its in there its ok  😀If its in there and its not ok then the people who put it in are legally required to repair the problemsTime for a cup of tea lads  😀
