Pennzoil Platinum is fantastic oil. I put it in any car I do my own oil changes. I haven't done my own UOA but everyone else's which I've seen looks good, and where this oil really shines is in direct injection engines with its superb fuel dilution resistance. Look at Mobil 1, Castrol (non German), etc. fuel dilution is always greater than 2% (up to 4%) at normal oil change intervals in direct injection engines, but Pennzoil Platinum is typically 0.5, sometimes maybe 1%. PurePlus is a surprise development for this budget oil, I didn't use it in my cars last oil changes but I have a jug in 0W20 and 5W30 on standby.
I started buying jugs of 0W20 for my Mazda 3 in the US whenever I happen to be there, $26USD at Walmart, good stuff. You can only buy 0W20 by the litre here and it occasionally goes on sale for $6.29 at Canadian Tire. 5L jugs can go on sale for under $30 here.
