[Oletrucks] Valvoline Restore & Protect

[MIQ MILLMAN]

I heard that the reason we don't want to use synthetic in the older engine
tech is due to the use of cork in gaskets and the larger tolerances between
machined surfaces and bearing surfaces allows for the much higher viscosity
oil to let bearing slip or rotate.

If you have heavy carbon buildup the additives, combined with a good ole
fashion Italian tune up  (i.e. give it some spirited driving at decent
revs), sounds be fine.

I would change the oil back to some high zinc content Dino juice after
4-500 miles.
