We know that seals in an engine are used as a barrier to prevent leaking around rotating components.
Note: We are NOT discussing pan or valvecover gaskets, which may or may not be constructed of synthetic rubber (elastomer).
Let us assume we have a fully formulated oil complete with either a synthetic or mineral oil base and additives.
Which of the following components has the potential to attack seals and cause leakage if not properly formulated?
Please Priortize them as worst and not so bad.
Hint: Pick only two as there are only two real possibilities.
A. PAO Base oil
B. Ester Base oil
C. GI to GIII Mineral Oil Base
D. Viscosity Index Improver
E. Dispersant
F. Detergent
G. Rust Inhibitor
H. Oxidation Inhibitor
I. Metal Deactivator
J. Defoamant
K. AW/FM package.
