Not true. Blindly trust? Please. No way to verify? What?
And the base oils Mobil uses, they sell.
There is no way that Amsoil can verify the actual chemical composition of the base oil that they buy. Amsoil does not have a lab nor can they hire someone to break down the chemical elements nor component ratio of all of their base stocks. For example, how would Amsoil know what they are getting is POLYALKYLENE SUCCINIC ACID, 1-5 R53 POLYAMINE DERIVATIVE (CAS 147880-09-9)? Or a compound represented by the formula:
R.sup.1 R.sup.2 N--C(X)S--(CR.sup.3 R.sup.4).sub.a Z (A-I)
wherein in Formula (A-I), R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently hydrogen or hydrocarbyl groups, provided that at least one of R.sup.1 and R.sup.2 is a hydrocarbyl group; X is O or S; a is zero, 1 or 2; and Z is a hydrocarbyl group, a hetero group, a hydroxy hydrocarbyl group, an activating group, or a --(S).sub.b C(X)NR.sup.1 R.sup.2 group wherein b is zero, 1 or 2; provide that when a is 2, Z is an activating group; and when a is zero, Z can be an ammonium, amine or metal cation.
Amsoil relies on MSDS like everyone else.
If you don't know what the base oil is then how can you buy it? Mobil formulas are proprietary if not top secret so how would you know what it is to buy?
