Hi,
Would you use Group III 5W-50 oil? Group III
by its very nature are smaller chain molecules
which without viscosity modifiers cannot achieve
viscosity higher than SAE 30 (from Bob's
excellent presentation on base stock)?
So, a Group III 5W-50 oil (such as Castrol
"fully synthetic" 5W-50) should have loads of
viscosity modifiers which will shear easily over time
right?
