Mocked? I thought we all moved past the base oil picking.Wish they made a Signature Series High Mileage 3.4 hths oil. No qualms with the SS line, but the lower tiers are just being counter to what they mocked the standard synthetic of being. Royal Purple in that category too with their Dexos line and the rebottled Kendall from Redline.
