Adjustments for gasoline octane 95

[hru]

Hi Roy & Anders

The theme is very interesting - specially for us in Denmark, where 98 with MTB is almost banned !

I have tried earlier with 95 (by mistake of course  ) - and it was no good experience with the pinking.
It was very clear to hear even with small accelerations. Pushing the acceleration was not an option.

But since the thread was startet, I have now tried the shell V-power which is 97 octane.
It seems to work, however I will adjust the timing a little - maybe 1-2 degrees or less.

I don't think the octane booster is an option, the price for a small bottle is ~12-13 EUR - and one bottle pr tank - no, crazy.......


Another thing I have found interesting is the approval of unleaded fuel from Peugeot.
Since a lot of us matra-freaks uses additives....... - but it is not needed.

Anders, I will find Bagsværd one day, when I have the Murena on the road again

for me I roll with the SP95 without aucuns problems.

specialist MURENA (politecnic) has me that it was useless to modify the synchronization of lighting to roll to the sp95 if a pointed camshaft is had ("the maximum road" for example)

Interesting.
There could be differences from country to country in the compositions of the petrols.
Roy has probably tried 95 octane on a Holbay "fast road" cam, which will be similar in period to the Politecnic cam.
