Without looking at month, it was 2 years since the last post. Seemed to bother you hence my explanation.It is older than 2 years.. 2014 then to about 2017, I wonder how much things have changed. So you are at more than 4, almost 5, and then 7 years for thread start.
Purchase from rep not required. You can order straight off the site.I think it is strange you have to buy Amsoil from a rep, sort of like Snap-On and I have thought about spending some coin on it.... Then we get into the debate about how good Amsoil is. I have seen several videos where I am sure the same result could have been achieved with even Mobil 1, which is also a fine oil, as are many others, not sure there is a bad oil out there if it is the lastest or previous API rating and has the Starburst.
Several years ago (12) I was driving 30k miles per year in a NA port injected vehicle. Tested Amsoil, M1, ST Syn and VWB at a 5,000 mile interval. Wear numbers were very close for all the oils*
Where the results differed was in how depleted the oils were. The VWB was pretty much done, M1 and ST had some to go but the Amsoil looked almost new. I later ran Amsoil consistently to 12,000 miles...but the other oils wouldn't have made it safely that far.
So the value - at least at the time of my test - in using Amsoil was getting up to twice the miles out of the oil than from another brand. And at the time you could get it for less than twice the price of the others so it was a no brainer financially. Not to mention reducing environmental impact by cutting the amount of oil used as well as waste oil.
To be fair, Amsoil has increased their pricing quite a bit more than other brands so are no longer 'only' twice the price. Further diluting the value is moving away from PAO in their SS oils (at least to some extent, they won't say). They still make quality products, but for these reasons I have since switched away from using their oils.
*M1 created about twice the iron wear as any other oil during the tests. The Jeep 4.0 engine was famous for not liking M1 for some reason.
