Just a few words of praise for Millers 20w50 Classic Performance engine oil. My 1500HL has the classic "crank rumble" at about 3000 RPM, but replaced oil and filter yesterday with Millers and did a round trip today of about 100 miles to a show, mainy main road 50/60 MPH,3000 rpm+(no overdrive) and sweet as a nut not a "rumble" to be heard.
I know what oil I'll be using from now on. Anyone else have any experience of this? Happy motoring. PJBAnybody got any other recommendations?. I would like to know of any other oil that I could use in my 1500 HL.
