I was in my local Canadian Tire Store having winter tires put on my Cavalier. As I had a afir amount of time to kill, I naturally went over to the oil section and read lots of bottles.
I was looking at a brand-new bottle of Quaker State 'Ultimate Durabilty' 'Horsepower' synthetic. On the back of the bottle, it says (paraphrasing) 'QS-UD-HP offers the most protection of any synthetic oil*'
If you look below, the '*' part sets out the following two things: a) based on the sequence IVA test; and b) of 5W-50 synthetic oils.
I found this really interesting, as it means their claim for their syn oil is based on testing a grade that is hardly used in the NA marketplace! It also severely narrows down how many oils it competes against - Castrol, M1, and maybe Roush Racing. PP could go on that list, but it alrady a SOPUS product.
If you look on a bottle of the dino version of QS, it makes the same statement, but says based on the 5w30 grade. So for regular oil, they test a mainstream grade, but for the syn, they test an almost unused grade!
I found this weird, and bit mis-leading.
