    So just to get a better understanding, I can happily run either 93 or 95 and have no worries of the bike/car packing up? All are FI.

    Spanner in the works, I'm importing a vehicle directly from Japan in the new year, hope our fuel will be OK.

    MUCH bigger problems than octane ratings.

Therefore 93 is safe at these altitudes.

    What this means for a turbocharged motor, I'm not sure.

    Interestingly, my Fazer runs a 12.2: 1 compression ratio and yet can run 87 octane safely according to the manufacturer: go figure

    Uhm... you get 93 and 95 inland. At the coast only 93.

    How do you "import" a vehicle directly? That is illegal (to protect our local motor industry). You can but a Japan import but can only use it in Namibia, Botswna, Zim or Moz. You cannot license it here. And certainly insurance is difficult because parts availability is lacking outside our official range.

    There are some outfits that import "grey" bikes. But they are risky and the official importers won't honour any warranty claims. (Usually you see them with 'mph' clocks, etc.

    Disagree; I suggest you check your facts.

    I have a 2004 KLR650 imported and sold by Kawasaki South Africa which has the speedo predominantly marked in mph as well as in (smaller) km/h. (Odo reads in miles). The headlight beam is correctly orientated for riding on the left.

    Riding a straight and smooth road does not make a skillful rider.

    Interesting discussion.

    With regards to Sasol, I was under the impression that they only have 10ppm diesel, which I have used from time to time on the diesel vehicle. I have always used one brand of fuel 95 on my bike (2003 R6) and my car (Astra OPC). One day while running low on fuel, i stopped at a Shell garage and proceeded to fill up the Astra with 95. Later on I realized that the car felt a lot more responsive and was wondering if in fact it could be the actual fuel. As far as I knew all fuel in SA originates from the same place, ( I could be wrong). Tried the same on my bike, and the bike felt more responsive as well. Now I stick to Shell. My fuel consumption did suffer a bit on both car and bike.

    The above is my experience and my feeling with both the car and bike. Its not scientific as neither vehicle was put on a dyno before and after. Has anyone had a similar experience?

    While I am usually the first person to say, petrol is petrol I get the same feeling with Shell. Is this imagination? I don't know as there should be no reason for this to happen.

    I'm a bit hazy in the memory department but I recall it was along the lines of Time magazine, in the early 90's, ran 3 identical cars on 5 tanks of fuel, each car using a specific brand only. Cars using Shell were running better at the end of the test.

    My question was "How much did Shell pay the Journo's?"
