the fortuner actuly smooths up a lot more than one canm think of after the 1st oil change i would insist on 1000kms and 5000kms [toyota says 10000kms] to actuly make your fortuner stay for a life time my recomandation will be change oil every 7500kms if u stay in a metro city in which traffic is an issue it will not only increse the life of the engine but will give u the best performanance and fuel economy and rely only on toyota recomended oils coz they are all perfect and relible my advice and choice only toyota recomendation product another important advice gain a perfect knowledge about 4WD before using them or experimenting them on your own fortuner coz originality and virginity are same one lots cant be gained again so use ur brainIt is just Touch the perfection of 1 can actuly understand what perfection isproduction must be increased and the suv must be made little more affordable no problem it TOYOTA
