Interesting stuff. Royal Purple did really well.

And when Amsoil does tests their products always turn out better results then the competition. You shouldn't make an oil choice based on one test. It seems the more unrealistic the "test" the more people think it's a better product.,,

 

I've used pretty much everything. I don't really think that one is much better than the other. Just thought the test worthy of discussion.

 

Too bad none of the companies have the cahonies to use engines for the testing procedures and then tear them down.

They'd all go out of business and Walmart oil would be the number 1 brand.

 

The "No engine is built this way, nothing works like this " Test, not worthy of reading. No offense to Subduedracer meant.
