A buddy of mine has an old Ford that uses a little oil, TCW3 in the gas has reduced his oil use.
How about those Amsoil filters for Toyota, cut the sevice interval by 10,000 miles, drop the price less than $2. STRONG.........Oh yea and they failed to deliver as promised. So much for testing the finished product.
As far as pulling oil off the shelf to test, Amsoil doesn't have to worry about SSO and ASM, no testing to fail, they aren't part of it.
The GF is ready, I'm out of here.
