If I continue to change the oil myself Edge 0w20 will be my choice. They lowered the NOACK from 13.3% to 10.9%. I’ve been impressed with Castrol’s TBN retention since their SN formulations came out. Castrol was also one of the first to go with the Mg/Ca combination along with M1 putting them ahead of the curve in that area. I will be curious to see how well this oil holds up going forward.
