I’ve had around a dozen soarers some of which i did over 400k without having to open the engine or auto trans. Here’s my opinion:
Engine oil i used to run HPR 10 but found the 5W40 to be much better.
Trans oil ONLY use toyota TIV (type4). Anything and you’ll be changing your trans.
Spark plugs i only ever use BKR7E in all my JZ motors. Tried everything else but found these performed the best and last for ages. DexIII for power steering.
