Title: What kinda gazoline?
Post by: njesper on May 25, 2006, 12:45:04 pm

yep, I'm a looser... have ordered the manual for my murena 2.2 (81) but havent received it from germany yet.
I've started working on it, and I still don't know what this beast drinks... Could somebody enlighten me on what kinda petrol, I should fill it up with?

I'm living in Denmark, so this lame question goes out to a dane, that feels pitty for me  ::)

Best regards,
Jesper

I am driving on 95 unleaded, and I have done so for approx. 10 years and 50.000 km with out any problems.

Will that go for a standard 2.2 "s" version aswell?..(assuming that the cylinderhead hasnt been skimmed to increase compression)
Im picking up a murena this weekend that has had the engine modified to "s" spec.. and the owner tells me that he feeds it a generous amount of octanebooster...

I always ran my 2.2 S spec engine on Shell Optimax with Millers VST additive which gave an octane rating of around 100. I think you could run on standard 95 Octane OK (Hans has proved this aleady!) as I believe the valve seats are hardened as in any aluminium head, but you would need to back off the ignition a few degrees which would lose the sparkle in performance.

Yep. However, this will often make the engine run a little hotter - so make sure the cooling system is up to spec.

(well, - of course we should *always* make sure the coolingsystem on our midengined cars is up to spec.)
