If you stack Redline 5W-40 against HPL 5W-40
What’s the major difference between the two brands ?? Lots of smart oil guys on here to explain
Not too much but I'm not sure the Redline is completely VII free in 5W-40 guise.
I can't have HPL, Redline high performance series would be very high on my short list of desireable oils. HPL will have a stronger detergent pack though
