So we all know the engine oil side of this has been beaten to death thousands of times. This is only about the Mercon LV/ULV, and using LV in the stead of ULV:
I “assume” additive formulations are likely extremely similar other than viscosity, can anyone confirm? I had some DM chats with some well-respected members and it seems the consensus is the ULV is so thin to help mileage on startup, but also that the Mercon ULV (10R80 in my case) is a pretty darn good fluid in its own right; very shear stable and holds its viscosity well.
Problem is, I had a brain fart and bought a couple gallons of LV equivalent instead of ULV. So… other than a small hit to mileage, and likely having to clear & retrain the shift logic, is there any downside to running a PAO-based LV in a 10R80 that calls for ULV?
100*C viscosity is like 6.3 on the LV I have, and the ULV is like 4.6, which means there’s about a 25% difference in operating viscosity. Thoughts?
