I've been on the sidelines reading all the forums everywhere and three years latter the bottom line from my observation is,
1). There is no mention of Quaker State's Ultamate Protection's GTL content. QS won't label it anywhere on the bottler or web page so it's all a guess with no science behind it.
2). Some have e-mailed SOPUS and asked and the responses were both yes and no to the GTL content question.
3). Some have speculated a blend with percentages such as 40% GTL with the remaining differece being Group III and additive pack.
4). SOPUS cannot let Quaker State beat its more premium designated brother Pennzoil which does identify the use of GTL but again at what percentages do each have?
5). I, and I suspect many others, will never subcribe to extended oil change intervals beyond 5K which seems to be the main marketing difference between QS FS and UP so is there trully a benefit for a oil rated 20K?
6). GTL allows for lower additive pack levels such as ZDDP, Molybdenum and detergents and I've read a 5W30 Blackstone lab virgin analysis that matched this statement however if both oils meet the same certifications, does it matter how they got there?
7). Finally, prior to the recent shortages with price hikes, I get the argument of "for $3 extra dollars, why not?" My answer is since SOPUS is not being transparent to the consumer with Ultamate Protection's real advantages and GTL content, I'd rather save the $3 and know at least what I am paying for.
