I love the oil, it was the thinness of it that was pretty eye opening. I checked to make sure I picked up the correct viscosity, which I had. :thumb3:

Where do you get your Amsoil from? From my research, directly from manufacturer seems to be the cheapest in this instance...

oil threads always stick to the top for so long, because everyone has an uneducated opinion based on limited personal experience to share. For example, doing 150K miles on a 4runner without blowing your engine on a certain type of oil is not a objective fact that an oil is good or bad, since you'd do the same with the cheapest wal-mart supertech oil. Oil analysis's, engine tear-down + inspection, laboratory oil stress tests on a particular oil are objective facts. One example is this: https://540ratblog.wordpress.com/
And then when someone goes out the way, and tell something researched, based on real facts, for example streetcreeper where we could even go deeper into oil flow VS viscosity, most of the time the person gets condemned, and the sheeps just go back to believing the former cliché oil folklore that is not even applicable to car and oil of this century
This is why I do not participate in .... oh well I just did.

You just summarized 99% of all auto and other type of forums.
The 1% that have knowledge are posting in-between all the other lines. But it takes years of reading the forums to discover that.
Why not sign up online as a preferred customer......their shipping here in Ontario, Canada is a bargain (online order). AFAIK, the preferred customer and dealer rates are the same if you are just buying for yourself.
Streetcreeper added a lot of good info, but he was missing one thing that I think led him to the wrong conclusion.
Cold 0w20 is still thicker than hot 5w30, so there is no issue with low pressure. The engine tolerances were designed for the hot viscosity and you should not mess with that number. Really by his own logic he should be using 0w30, and I would do the same if I was him. All of our engines would gain flow at low temps with 0w-whatever oil, the only hang up is that has to be synthetic (conventional additives can't go that low) and not everyone wants to pay that premium.

I'm tired but I don't see how cold 0W20 which would approximate 0 weight when cold, is thicker than hot 5W30 which would approximate 30 weight when hot.
If you are not too tired to watch the video in the first post, you will have your answer with nice colorful graphs.
Ok, some dude sponsored by penzoil, on the internet, with graphs.
Well, you wouldn't want facts to get in the way would you. Even if he was a shill for an oil company, would he have some reason to lie about how viscosity works?
