AMSOIL Crushes Sequence IIIH Engine Test

AMSOIL puts it’s Signature Oil to Severe Test. Good Video and article tell how AMSOIL “crushes” the torture test that screens oils and their ability to protect todays modern hot running engines! Also a good video on what Amsoil Signature Series Oil was put through during this grueling series of tests. AMSOIL has a superior additive package enhances it superior synthetic base and provides the ultimate protection one can get from a synthetic motor oil. It tells how AMSOIL is committed to not just being “good” but AMSOIL is committed to being the best with their products and submits them to tests against any other oil to prove it.
