I have bought a buick regal custom 3.1 L engine. Done about 58K kms only original. Not been used much in brand new condition. I have a problem that it doesnt give me a good fuel average. I get about 6 kms a litre only in city under normal driving conditions without much traffic. Is this normal for this car. If no then can anybody guide me what could be the problem. I use 88 octane gas and the condition of the car is excellent otherwise. The pickup, power and engine is great. Pls help me. </font>
