Yeah the previous post is absolutely correct..... what ive seen from experience though is that 0W oil is extremely thin..... and easily leaks past worn seals. In addition to that, if the engine burns oil at all, it will be even worse with 0W oil as it will escape past the rings and valve seals easier and be burned in the combustion chamber. Its good for efficiency with a newer engine (doesnt impede crankshaft rotation as much as a thicker oil), but on an older engine it just burns off quicker. I personally dont trust such a thin oil.... especially if you plan to do freeway driving or live in a warmer climate. 5W/30 is thin enough lol.
