for one thing it has a really high TBN which i believe means it is a very robust oil that will last a long time. And from looking at how others did in the four ball wear test it seems to have a very short wear scar.

also i looked at the pour point and the flash points but after another look i think i was looking at it wrong.

the other is the torco regular synthetic oil
when i said #2 was better that was based on the numbers btw
i didnt just say it was better because i knew it was amsoil


Based on the numbers I believe #2 will protect your motor better. (who am i thought right, lol)

but #1 does look like a very good product.

Where is the best place to buy amsoil at online? I dont know if any part stores around here carry it.

Also, theres a few variations of the 5w-30 grade, any suggestion on the better choice. Done some searching, bet others would like to know too.

Thanks in advance.
