They did the same test in a controlled environment, so to me that proves which oils are on top of what. If you choose not to believe them, don't. I have been using these types of oil, trying the 'good' ones that have been tested - and they are awsome.
Adding a quick word to aaronng's comments.

Not trying to start a riot here, but how do you come to your conclusion that the oils are "awesome"? I mean I know people that have only run OEM mineral in (10k service intervals) and after 300,000kms there cars still run well and show well under compression tests. Even when i made the comment about the FUCHS oil its only based on colour, burning volume, engine noise and torque band. Even that isnt really enough to prove the oil is that great.

What aaronng is trying to say is that if the tests were conducted in a way that is irrelevent or not well suited to the use of engine oil then the data gathered is inconclusive at the very least.

Important Note: Just because they are the 3rd party doesnt exclude them from bias. A motor vehicle magazines opinions or conclusions are most likely going to have an effect on an audience, otherwise what would be the point of even publishing it? Thus attracting attention of Motor Oil Companies, there is no proof to say that penrite didnt pay them or financially support their research, thus the possibility of bias exists.

BTW, My self and 2 other friends have tried penrite oil in gearbox's and although it is a gearbox and not engine, i can tell you their Transmission products are absolute garbage. All of us experienced very noticable notching in third/second and stiffer changing all around. The gear changes were horrible at high rpm. My transmission seemed to be in better condition so the notching was rare but stiff changing was always there. And the absolute inability to cope with wide temperature ranges. We replaced it with OEM MTF mineral oil and havnt looked back, smooth gear changes and no notching whatsoever. One used a Mineral Based Penrite oil and other two were using the "SIN" synthetic transmission oil and they were both the same viscosity. I find it hard to believe that the quality of Penrite's transmission oils and Engine oils would differ greatly if even at all.
