Hello everyone, I am wondering if anyone has any viscosity curves for 0W vs 5W and/or 10W oils with the same hot viscosity. I have tried to find example curves but I was not able to find anything and I am curious at about which temp the cold viscosity actually starts to significantly differ. On all the data sheets I have seen, the differences in kinematic viscosity between 0W, 5W, and 10W is negligible at 40 degrees C (104 degrees F). But what about on cold starts in moderate weather of, say, 60-80 degrees F? Cool but not bitterly cold weather (30-50 degrees or so)? I realize that the exact viscosities will vary depending on the exact oil, but if someone has some information or viscosity curves they could share that would be very helpful in helping me understand the approximate differences. Thanks in advance!
