Sometimes engine makers like VW will command that for certain engines like their TDI engine that you not only get the weight right, but you must also only use motor oils that meet specific standards, if you don't want to damage your engine. Mechanics will tell you not to worry about it and use whatever oil is sponsoring their favorite NASCAR driver, mostly because they have no idea what their talking about.
Yet another completely stupid-arse post.
Mechanics know what we're talking about. You obviously don't.
By the way, it's pretty obvious who you are - and that as a "previous user" that got banned, you've just come back with another name.
If you arent burning any oil, I would stay with what is recommended. However to those tooting the horn to ALWAYS follow manufacturer recommendations, I don't agree. In real world, some users will find that other weights work better than what was recommended. I think the subaru wrx community is one of them.
Back on topic, if youre not burning oil, use what is recommended, once you start to see youre losing oil either at the dipstick or visibly burning, I would go heavier to compensate. I had a 240sx that burned oil on the lighter recommended weight, so I went heavier and it never burned.
Shoot, Teddy, well you should know then that just because Toyota does extensive testing and engineering to arrive at their oil recommendations, actually all of that testing and research means nothing, and if you really want to know what oil you should be using you need to ask a mechanic that will make a recommendation based on absolutely nothing but their own lack of knowledge and understanding.
Think about it, who knows more about automobiles, the Toyota Motor Corporation or some mechanic?
No doubt the car manufacturers spend millions researching their brands, but you do know there are recalls all the time right? So the engineers know a ton but, dont know everything, and when placed in real world situation by the thousands, unforeseen errors arise.
I think both the engineers and those mechanics that focus on specific brands need to get their recognition. Plenty of mechanics (even the backyard wrenchers) know plenty of ways to make a car better, which is slightly subjective. But the manufacturers make most cars suitable for the the average Joe, completely limiting potential and keeping it as idiot proof as possible.

Of course there are mechanics out there that are extremely knowledgeable. But to say that engineers - the people who design engines - know nothing about them really makes you loose credibility.

Let me guess, here come the personal attacks...
Engineers don't write owners manuals. And you will not find me saying that engineers who design engines know nothing about them. Better do some re-reading.
...also, the proper word is "lose" not "loose." Thank you.

------" there are recalls all the time "......
WHEN was the last recall for engine failure due to the recommendation of the wrong viscosity oil ?
WHEN was the last time they had to warn owners that their viscosity recommendation was wrong and it was now being changed ?

That's what I was referring to. You got some conflicting statements going on.
Thank you for pointing out my typo! No one would have known what I meant without that correction.
