hier noch was bzgl. Oktanzahlen in US:
United States: in the US octane rating is displayed in AKI. In the Rocky Mountain (high elevation) states, 85 AKI (90 RON) is the minimum octane, and 91 AKI (95 RON) is the maximum octane available in fuel[citation needed]. The reason for this is that in higher-elevation areas, a typical naturally aspirated engine draws in less air mass per cycle because of the reduced density of the atmosphere. This directly translates to less fuel and reduced absolute compression in the cylinder, therefore deterring knock. It is safe to fill a carbureted car that normally takes 87 AKI fuel at sea level with 85 AKI fuel in the mountains, but at sea level the fuel may cause damage to the engine. A disadvantage to this strategy is that most turbocharged vehicles are unable to produce full power, even when using the "premium" 91 AKI fuel. In some east coast states, up to 94 AKI (98 RON) is available.[23] In Colorado as well as parts of the Midwest (primarily Minnesota, Iowa, Illinois and Missouri) ethanol-based E-85 fuel with 105 AKI is available.[24] Often, filling stations near US racing tracks will offer higher octane levels such as 100 AKI[citation needed]. California fuel stations will offer 87, 89, and 91 AKI (91, 93 and 95 RON) octane fuels, and at some stations, 100 AKI or higher octane, sold as racing fuel.
AKI = (RON+MON)/2
unser 95er (Super) also = (95ron+85mon)/2 = 90 AKI
unser 98er (Super+) also = (98ron+88mon)/2 = 93 AKI
quelle:
https://en.wikipedia.org/wiki/Octane_rating
manchmal wird der 95er Super auch mit 88mon angegeben sprich also = 91,5 AKI
also bei mir 400-800m Seehöhe dürft der 95er keine Probleme machen.
(weiß noch von diversen Einstellfahren bei einem eingespritzten Einzylinder Motorrad, dass die Seehöhe kein kleiner Faktor ist!)
es geht hier nicht ums Geld sparen (die 10€ pro Tankfüllung...) nur um zu wissen wie und was.
eins wär noch interessant: Wie heiß wird so ein LS7 bei Landstraße/Passstraßen auf schnell und bei 20°C Lufttemperatur (85-105°C Motoröl?)?
