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
Thanks![]()
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
