Hi,

I presently own a 1996 Nissan Terrano (TD27-Turbo Diesel) engine. My tire size is 265 X 70 R 15. My problem is the mileage per liter of diesel is only 5.5 Kilometers per liter. Is this normal eversince I acquired my Terrano 3 years ago its been like this already. I had the injection pump calibrated and the engine checked which is in very good running condition. Is there a way for me to enhance my engine to increase my mileage. Thanks for your help.

Check your inlet tract for cracks or leaks.
