Different applications and additive packages. Both great oils in their niches. The SS needs to reduce the Zinc and Calcium to get an API SP rating due to catalytic converters and need to prevent low-speed pre-ignition. The Premium Protection can up the ZDDP levels as it's not going for the SP rating but is awesome for classic cars, classic motorcycles and power sports as well as all your power equipment without catalytic converters.
Do you ship to the UK ? you know anywhere in the UK parts company sell your oil?
