Hi,
I have a Rover 220SD on S-Reg with 110K on the clock.
When the car starts being a diesel I expect a bit of smoke out the exhaust. However when the engine has reached its running temp (half way normally) and If I rev it to 3500 RPM and above it chucks out a whole load of soot from the exhaust and leaves a black mark on the road. Is this normal?
I am going to change the oil on the weekend to see if this makes a difference (using Castrol GTD 10W 40). Is there anything else I could do to perhaps reduce the amount of soot it produces. The car is not miss firing or does not have any other trouble i.e. starting up etc ..
Appreciate your comments
Regards
