In a recent post comparing Quaker State Full Synthetic to PP a member claimed that his Subaru went through PUP as if he'd "left the drain plug out". Has anybody else found their engine used more oil when running PUP?
I ask because I have a decent stock of this oil (SN rated) that I was planning to start using in my daughters Mazda CX-30 but won't if this is the case. Her Mazda burns no oil in the 5 to 7K OCIs that it's had using Quaker State Ultimate Durability, M1, Idemitsu 0w20 syn. and PP and even with the Citgo syn. that Midas used when she was far from home. Since I don't get to keep an eye on the oil level of her Mazda as I do with my own cars I'd save the PUP for my cars if in fact it tends to burn off in some vehicles. (I'm pretty sure she never looks at her dipstick despite my teachings.)
PS: I even have 2 OCI's worth of the 5w20 SM PUP from 2010 that was a darling of this site when it first came out...I'll probably use it in my 2008 Corolla which was back spec'd for 5w20 and calls for SL oil on the oil cap.
