I normally fill up with BP fuel and average around 13lts per 100km. Recently I was driving on a new section of highway just North of Port Macquarie and was getting low on fuel so filled up at a new service center (Puma). I noticed that the fuel gauge was dropping quicker than normal but though it must have been due to headwinds etc and never though of fuel although the car felt sluggish I thought and as I've owned the vehicle for 21 years i'm pretty tuned to any change in behaviour. When the fuel light came on again at the end of the trip I filled up with BP Ultimate and noticed that the previous fill had averaged 15lt's per 100km which shocked me. Anyway after driving another 10km's on the BP fuel the car felt more lively again so it will be interesting to see if my average has gone back down to 13lt's per 100km when running BP fuel.
I did a bit of googling and found that the Puma fuel can have up to 20% bio diesel but I'm not sure what we purchased as my Wife binned the receipt.
I also came across this post when researching PUMA fuel so think I will stick with BP or Caltex from now on.
Lindsay transport just did a 6 month test using BP ultimate diesel in two of their Kenworths. They had a full history of the trucks and after the 6 month test they went back to truck diesel for another 6 months. There finding was that the trucks returned 3% better fuel consumption with the ultimate diesel and when the heads were stripped the combustion chambers and valves were in good nick with little carbon. One thing is, the ultimate diesel is dearer than standard diesel.
