So most brand name manufactures don't OEM their product lines to get all the sales? Canadian tire oil I was told many many years ago that it is made by esso? not sure if they still do this.

one thing i found outt over the years is that very few oem MAKE things, they buy and rebox

Yes that's what a lot of companies do you can buy products from the manufacture and they are not marked with the company name. They give it to you in a bulk box and you box it and put your instructions in it and you save a lot of money.

For computers it is easy to find out who made the product as you go to the FCC ID site and type in the FCC ID # and it shows you everything.

Do they do this something like this for auto parts so you can find out who manufactured the parts?

im sure they use an id somewhere but it will vary as many times as there is parts.

Canadian Tire oil used to be made for them by Esso, I believe you are right Evan. They had their tires made for them by General and Goodyear too. At least when I worked there 15 some odd years ago.

I have not used a GM brand part on my Thunder Car ever, that I can remember. Not that I would go to the dealership and buy anyways... But that doesn't mean that we do not use "brand" parts... it is all about buying quality parts for the area of the car you are working on. Most of the new parts I have bought are specialty racing items.

And as far as pistons go Thayne, Wiseco is not the only manufacturer. If you do some research you can find some interesting SBC pistons. I forget what is in our engines LOL. It really isn't all that important anyways right?  😮 ;D
