George,gear oil is out of context in this thread,turbines are not "shocked" either,they stay spinning.You are also speaking of posi trak units,not the manufactures of ring and pinions.Another topic post you had was about a limited slip unit,,try a ring and pinion company like US Gear ect,would be curious to knw what they recommended. But some syntheic gear oils are just plain better than others it seems,gear oil is a topic that is not of much interest to me
I do not believe you have been around to modern motors with upwards of 900lbs of open pressure the nose of a roller cam,,,ect ect. These thin multi wts are a great way to kill a 15k+ dollar motor imo with logetivity in mind.Not a 200 mile race and throw the parts away.
But while we are here,you might be able to tell me why two street strip motors running only 450 lbs of open pressure only allowed the roller lifters to live 2k miles on one engine,3k on the other with Trysyn 15-50? Also might be able to tell me why Trysyn seemed to shear and allowed two other BB Chevy's with Vasco jet springs and 800-900 lbs spring pressure,motors well over 10k each to get metal to metal contact and got the lifters sideways right quick and killed both motors? Yet,a straight 40 wt VR1 with a additive on the BB motors was added to all 4 engines after repair and the first two now have 7k and 9k repectively street miles on them.These grenade pins were pulled at others expense,not mine
I understand the credentials you have in your sig,I ask how much hands on Race Motor building experience you have?These guys such as Falicon are experts and pioneers in their field and I would presume to be far more knowledgable than most about oils even furthering with feedback from the field yet they are challenged?. Same goes for cam manufactures,show me one that recommends a multi wt anything for breakin if the cam,and to further,you will not find one that will warranty a cam broke in on Synthetic,,not one! The only way out is "if" the cam company knew the builder and a straight wt syn was used
Also,I had asked you a question in another thread,it went unanswered about the fact you said Wallace finished a race the other night on Mobil M1 30 wt,it seemed to allude to he uses a OTC Mobil oil,,I do not believe that would be the actual case in high end racing like that,I will pull the thread and post here since it must have been overlooked

The 30W Mobil 1 should do just fine. Indeed the 40W will cut into horsepower and fuel economy. You just don't need that much viscostiy in this vehicle. Regarding running 80 mph, etc. Rusty Wallace came in 2nd tonight at Bristol running 30W Mobil 1 oil at a fairly significant speed... Mobil 1 30W will not shear down unless contaminated by fuel/AF/H2O, etc. It will remain in grade, just as Mr. Wallace's did tonight at Bristol.. M1 30W series oils just do not shear, are grade stable. I have seen vehicles go 40,000 miles on Mobil 1 and oil analysis results indicate the same viscosity as new oil. I have never seen M1 go out of grade except by some form of dilution or severe blow by causing oxidation. And this is for literally hundreds of oil analysis results for fleets of company cars, vans, tow vehicles, etc.

George, I believe this is a Supersyn thread so with this in mind
{And this is for literally hundreds of oil analysis results for fleets of company cars, vans, tow vehicles, etc.
George }
Are you saying you have seen the
hundreds of Supersyn anaylisis results? Or Trysyn and prior? I believe the distinction needs made between the two oils as it may mislead some readers into thinking the two are the same or never changed
Also,I find it difficult to believe that the Wallace car uses a Walmart type formulated oil. Can you confirm that car uses a OTC oil in it please,interested in knowing.I am not accusing in anyway but this will be news to many if found to be true
