The 2.4lt 4 cylinder is the most reliable of the 2 petrol motors rodeo have. The 4 cylinder motor is made by Isuzu and they are the bullet proof motors. I have seen them go well over 600,000km with very very minimal servicing. My last Rodeo was a 99 duel cab V6 and I did about 160,000km with no problems before I traded it and my old man has so far done 200,000km on his 04 V6 with no problems either. I currently have an 05 V6 space cab which im still yet to get on the road
so it has only about 600km on the clock. The V6 is a bit thirsty but they have plenty of power and torque for towing and carrying a lot of weight. I think im going to get rid of my 05 and get the new Isuzu D-max, over 1400km on one tank so that sounds good to me and if its Isuzu then it must be good because I cant fault them from my experience.
