    High/Low octane settings?

    Just been told that AMG engines can be set to take high or low octane petrol simply by using the ignition key in 2nd mode; i.e., select 2nd mode and wait 30 seconds. Start engine and run it for 2 minutes, turn off and repeat once more. The engine is now tuned/mapped to use whatever octane petrol...

    Octane Booster ?

    A query... On the mongol rally, we'll be driving through places where the standard fuel is 78ron. I don't want to tinker with the timing, so was thinking of buying a box of octane booster bottles. Some claim 5-10 ron increase... but is it of any use? Ideas/suggestions? M.

    W208 320 Is higher octane fuel safe/worthwhile

    I have just bought a 2001 CLK 320 and really like it. Engine is nice and smooth and shows 25mpg around town and 29mpg on the open road. Would Shell V-power be better for the engine and give any increase in performance and mpg.

    Evo or Octane Magazine, both or neither?

    Although I have every copy of Evo magazine from day one I find it an annoying read most of the time with too many supercars and a feeling that Evo is slightly full of itself with all that ‘Evo-ness’ b*ll*ck. (however this months issue is excellent with it's £1000 performance car article) I’m...

    Myths about octane booster.

    Besides being horribly expensive (your prices are even crazier than ours!), they can hurt performance, not help it. http://www.youtube.com/watch?v=2jbcCr2ll3c

    Change in Petrol Octane

    My Merc A200 Turbo states in the guidebook that only 98 RON unleaded should be used. The onyl place we can get this is Shell with V Power but I'm not always near a garage. How damaging to the car is it to use 97 ron and what damage is done by using it in emergency?

    Suitable petrol octane rating

    According to the owner's manual, I can use a minimum 87 octane petrol if the car has no catalytic converter, minimum 95 octane if it does. Anyone know if my car came equipped with a cat converter? It's a 1990 230CE
