For HPL, Is the formula in the 15W40 the exact same as what we would find in 5W40 or 5w30?
I've heard that for Redline and some other brands of oil, its different. For instance, PUP 5w30 is not the same as PUP 0w40.
@JHoward Good advice, but he merely suggested a thicker oil like something from Castrol, Mobile1 or even Shell Helix. He's not big on specific brands.
My thinking is that we know what works.. Redline 5w40 / 5w30. It has a proven track record. However I am looking to do some testing in the same way that
@Hemi395 is doing on his truck and find an alternative to Redline in curing as well as preventing the tick.
From my thread
here, Castrok Magnatec 5w30 did not prevent the tick; even after a rebuild. So I'm left with curing it and seeing if I can cure it for good.
