At the moment I am filling in my SL R230, 3,7 liters, 245 hp, Bj 2003, the Super Fuel E5 with 95 octan How sure some of you have already noticed a new diesel fuel coming to the petrol stations in the next weeks The introduction of Diesel B10 (diesel with an addition of up to ten percent öko additional). For this the Super Petrol E 5 is taken out of the program. Alternatively you can then refuel Super E10 or the expensive Su by Plus. The question would be now, can I drive the “old” car at all the petrol Super E10, or would it be more advisable to refuel the Super Plus with 98 octan? Greetings and thank you in advance for the answers. Torsten
