New 4Runner, Amsoil or Toyota Oil?

It would have to be a pretty small particle to make it through you oil filter. Or its just going to lay in the bottom of your oil pan.

We have a BMW which is under their free maintenance deal too. In that case I know and am friends with the tech who I take it to, as we were both master techs at an independent shop back in the day. He's competent, and shares my annoyance at hacks who might touch and cause damage to our personal vehicles. So I let him do it, and visit with him in his bay while he does the work. I get to catch up with a friend, and he gets paid by BMW.

That's a cool deal... Win - win.

Can't beat that.

And that Toyota 0w20 oil has a interesting additive package in it.

To the OP and title question……IWMAD. Which oil is least Expensive? Just follow the OLM.
