Greetings! Newbie land ako and I need help. I had just recently bought a 2nd hand japanese pajero from subic, and my diesel consumption is at 6.2 km/l. Majority of my driving is on highway. My friends are telling me that this is not normal and the consumption is rather high. Was just wondering if there is something wrong and needs checking. Also i have heard someone saying that by installing a catalyctic converter i could lower down consumption. By the way, my pajero has a 2.8l engine.
