And contaminated with abrasive metals and water.......
I need me some of that
Rev 360 is off the charts. TBN 31.3 and 10,000 calcium.
Nope, although I only looked at the new Gold medal award winner, Rev 5w300, as all the wear metals are OK and the 20 ppm of Silicon is just sealant used to glue the lid on the can. Water just evapourates and it's good to see that in an oil, as it means the viscosity will fall during what could be a biblical OCI!
