Servicing Schedule - Toyota Hiace 1RZ engine

a lot of this depends on how it is driven and where, if severe conditions, like gravel roads sand etc it shold be done more often but normally oil /filter changes 5,000 miles air fitler at least once a year, twice if severe conditions, same with fuel filter. coolant change if green coolant every two years, if orange every 5 yrs. If an automatic trans every 50,000 and fan belt and tensioner every 60,000 miles.

What is the right servicing engine oil for toyota hiace 1rz engine, how often can one change the fuel filter because the filter is hidden under the injector housing. Thirdly, can I use toyota t-iv transmission fluid when the dipstick specifies dexron II. dexron II is nowhere to be found. Thank you.

preferred engine oil is SAE 5w30 which I marked on bottle for transmission fluid if it's an auto matic it's DExtron II or DextronIII or the Toyota fluid

next time please give engine size not model and what type of vehicle as well as stick or automatic
