My SV6 is now two years old, and just past 60,000 Km. We have just come home from ten days in sunny (???) QLD. I had the 60K service just before we left, and received a call during the day "recommending" a fuel injector service and throttle body clean, at about $200. I knocked it back. Since getting the SV6, I have done this trip three times, at about 1,500 Km, about 30,000 Km and now 60,000 Km. Fuel consumption first time was about 8.0 L/100Km and 7.8L/100Km at 30,000 Km. Both those trips averaged 90Km/Hr. This time it was 7.6L/100Km with an everage speed of 93 Km/Hr. The only change in the car has been replacing the original Bridgestone tyres with Goodyear LS2's. I just wonder if and when a fuel injector service and throttle body clean might be advisable? It certainly is not needed yet.
