Specialists out there, please humor me by answering my dumb question: Like the title says, has there been a recent change in the gear oil table?
I attach the first one (I don't know where I got it...) and if we want to focus say on 75W-80 - it says that (non-W) 80 wt has to be at least 7 cS viscosity at 100°C. If you look at the second table, it says the kinematic viscosity at 100°C has to be at least 8.02 cS. There are also changes in the 75W values... 4.1 cS versus 4.4 cS... ???? If I consider Pentosin MTF-2 it would be a 75W-80 according to the first table and not the second.
See the Pentosin bulletin, 3rd-up...
Anyone know what's going on?
