motor oil for 16V

[Ivan141]

Well I'm not advocating it as an absolute truth, just something that happened to me on 2 occasions. Both times on very tired old 4age's.
My current mazda 1.5l engine has also started consuming oil after an idiotic mishap 2 years ago (someone drained my gearbox oil and refilled 4 liters of engine oil on top of what was already there), and I have just stuck with the 10W40 specified for it. Consumption hasn't gotten any worse, so that's my strategy for this car for the time being (engine has 210.000 km's on it). Changing to thicker oil did jack squat for reducing oil consumption in 2 of my last 4age's in my ae86, just thought I'd share that for what it's worth.
If an engine is worn down, your probably not helping things much by pouring thicker oil in it (contrary to most advice I received back then).

As far as brands of oil: we are on the same page with that. I will not contest that some engines might require more specific types of oil, but those are mostly more modern engines, and even then a lot of the fuss can be avoided by just changing oil more frequently. This especially goes for the 20v 4age for example which has a habit of caking oil in the head because it runs hotter.
