Hi,

I think I could be one of the only one's here with a RAM 1500 ST 5.7 Hemi Quad living in Germany available here we have 95 Octane Fuel Saver, 95 Super, 100 Ultimate. Which should I use?

 

Standard Unleaded fuel in America comes in 87,89,91, or 93 octane. Assuming The "octane" is considered the same for America as it is for Germany, than I would say the basic 95 octane would be more than sufficient.

 

I believe germany`s "95super" is close to the same as our "89 octane" (non ethanol) in the usa.
Thats what a friend of mine told me that lives in germany anyway, but i could be wrong.
I would be running the german midgrade regardless, if it were me (95 Super)

 

The thing I forgot to mention is that my ENCS car dealer said that when the RAM went in for its European conversion he said the engine managemenyt had to be re-programmed to take the Euro fuel?!? Thanks anyway, I had noticed a slight difference on the Freeway (Autobahn/Motorway) That when I'm doing around 50 mph, I then nail it, I get more of a drop down on 100 Octane than the 95 Octane.

 

I used to live in Germany back in my pre-Ram days. German gas stations usually display the "Research Octane Number" (RON) while gas stations in the US usually display the "Anti-Knock Index" (AKI) number as the octane rating. A 95 RON rating in Germany is about equivalent to a 90-91 AKI rating in the US. So, as someone else already suggested - I'd run with the 95 over there. Not sure of the differences between the two different 95 octane fuels you mentioned - probably something to do with additive packages/cleansers.

More info on octane ratings and how they are calculated is here:

I live in Germany for 14 years, had two Hemi Rams there and now i live in Italy with my 09 1500 4x4 Lar. I think your ENCS dealer is on crack.. when you take your truck to the dealer in Germany he will put the correct USA updates on your computer.. they will NOT convert them to Euro Spec. As for the Gas, At either the AAFES or Esso just use the standard unleaded and you will be fine. BTW here is another tell tail sign, Can you get AFN on your radio? or are you one MGHZ off?
How bout My GIG can you get the GPS to work? Maps uploaded?..

BTW where at in Germany? I was at Graf and Vilseck for the majority of my time.

 

Every station I've ever noticed (in the Southeast US) uses the average of the RON and the MON (Motor Octane Number).

The yellow label usually says "(R+M)/2 Method"

edit: Guess I should have done some reading on the AKI before I put my foot in my mouth.... Looks like AKI is the same as the average of RON and MON! Who woulda thought that. I spouted off the above from memory, not even knowing what AKI meant. My apologies.

 

I was quite sure its in Octane rather than RON here, I'll check next time I fill up.

I live in Bielefeld in the mid north between Hanover and Dortmund. I've been to Graf twice now once in 96 or 97 and now this year or should I say this yr Apr 2010, love the camp lots of Brits travel the 600+ mile round trip just for the shopping!

PS I hand washed her today I thought I needed to get all that salt off her as we've been snowed in for the last 4 weeks, it's illegal to wash your car on the street, my ans would be its also illegal to do 51 kph in a 50 zone!

 

Also it seems that I only have analogue radio as I can't recieve SAT Radio.
