P.*. 2ALL: Yes, fuel in our country is a bit worse, than in US, but it is not leaded anyway since early 90'*.
My other car have no problems with fuel and there are a lot of people here, who own cars like Porsche Cayenne, Maybach, Maserati etc. I don't think, that all of them buy foreign fuel
just because i often see such cars right ner me at the gas stations.
The only problem, still existing here with fuel is high percentage of anti-detonation additives, such as ferrocene. Ferrocene should be added in extra-low quantity to increase the octane of the gasoline, but if this additive is in greater percentage, it will have bad influence on almost all fuel system - injectors, spark-plugs and some sensors. They shoud be replaced frequently if you use high-octane gasoline in Russia.
