Hej folk fra Danmark...

This summer we've spent our holiday in Denmark, unfortunately not with the Murena (way too small for a family of four, I even needed a roof box to carry all our stuff with the Peugeot 308) and we got some sunshine and some showers, but it was still better than back home in The Netherlands where summer was skipped and moved to autumn altogether!

I noticed that, apart from prices that may vary over 1 Krone per liter from town to town (*), there is no such thing as RON 98 available. You can get RON 92 and 95 (and Diesel of course), that's it. Quite different from the situation in The Netherlands, where 95 octane is the lowest octane fuel available, some petrol stations have 98 octane available as well (though harder and harder to find, most are switching to 95 for their "Premium" fuels).

How do you refuel your Matra's there? I never got mine working on 95 octane without early detonating, I put either Shell V-Power (which is RON 97 here) or BP Ultimate (RON 98) in the tank. I know there have been previous topics about this, and it should be possible to run the 1.6 and 2.2/2.2S engine on 95 unleaded, but I know very few people who actually do.

(*) obviously there was a price war going on in Ribe, I paid DKK 9,98 per liter Diesel, while in some places prices were over DKK 11 per liter...

Good to hear you had a nice holiday here - we think weather was horrible this summer!

Sure, we can find 98 RON. It's still available in a few places:

I personally run my Murena on V-power Smiley

Me too. I would have no good feeling to run my Murena with 95 octan. We have a "Shell" 18 kilometres away from here. That´s where i drive to, when i need fuel. Also when i´m travelling, i look everytime to the red/yellow sign.

This has probably been answered before, but I think we all can benefit from a recap....

I seem to understand that the Murena CAN run on 95 unleaded.
But what SHOULD it be run on.....?

Years ago, someone else published these pictures on a forum, I do not remember where I found them.


My Murena - indeed - runs well with 95 octan. However, this seems to be rather unusual.

The instruction manual tells you to run the 2.2 on RON 98 (superplus).
I stick to that.
Also the Shell V-power is only RON97, en my car has trouble with it pinging.

The Shell V-Power was 100 Octan when it started some years ago. But i think ( when i rember right ) actually it has in Denmark 99 Octan, doesn´t it ?

We have Shell V-power 95 and Shell V-power Racing 100, but due to our bluffers who are mixing it with something else, I hope that V-power Racing 100 has at least 96 octans as was Super which was prescribed for Murena. When I take this fuel or Super 98 in Germany - oh my god, the car runs like hell Shocked

Where did you find that in the instruction manual? I can only find they tell you to use super.

Of course it is better to be safe and use RON 98 in case you have doubts or expect problems.

As far as I know superfuel in the 80s was RON 98

Yep, that is the same I found and I could not find anything else.

The Murena instruction manual was written in the time we had leaded fuel. I did not find indications about the RON of leaded super in that time, but I remember that it varied in several countries and sometimes other indications than RON were used (MON, motor-octane number).

Unleaded fuel was introduced in 1986 and later. The guideline from EU (1985) ordered that unleaded super had to be at least RON 95.
So, I presume the leaflet I mentioned is from the second half of the eighties.
