Yes, I was given some to test and you can see some of the earlier UOAs in the appropriate area. It went 7.5K without shearing an iota, so we'll see when it's tested again at 10K. I have one more fill of the stuff but I am going to run an experiment with 10W30 in my 5.4L Ford when the OCI comes up. Looking for a mixed fleet oil I can use in everything here on the Twin Oaks Farm. The 10W30 viscosity comes close to fitting all my equipment, I'm just concerned about VCT operation in the Ford so I will datalog VCT ops, as well as oil pressure & temp to see what happens. If I have to drain it early, I'll put it into a clean jug and use it in a tractor.
I am a dino guy for cost reasons but don't need convincing that syns can be good oils. It's just that when I crunch the numbers, even with the advantages inherent in a PAO syn, it doesn't crunch for me... at least as it regards my goal of a "one-size fits all" oil for my "fleet.." 10K miles is about two years of driving on the truck. To reach the required OCI hours on my tractors takes as long as three years. I have verified that dino oils can do that and I don't doubt a syn could... but pushing past three years makes me pause. I have enough bypass filter setups now to equip the major portion of the fleet (except the Honda Accord) and that might be a possible answer too, but the financial logic is; "If a dino does the job well, why spend too much more on a syn?"
