I know this has been discussed at great length, but I just received an e-mail from Anglo American Oil and this cropped up Driven HR1 v Valvoline VR1 |

Interesting test results by Comp Cams in the US: Driven HR1 SAE15W-50 has a cam average wear rate of 1.778 microns per hour, whereas Valvoline VR1 SAE20W-50’s figure is 3.683! We were amazed that the Driven HR1 had less than half the cam wear of the Valvoline VR1!
After two hours of dyno running, the Driven HR1 oil also delivers more power (+2.75BHP) from the 5.7-litre scruby V8 test motor that Comp Cams use for all their tests.

Ted, do you recommend using something lighter than 40 or 50 wt. with metric rings?For the Ford Y, I typically recommend using a conventional grade oil with at least “30” in the viscosity rating (i.e.: 5W-30,10W-30, 10W-40, etc. Nothing less than “30”as the shear property of the oil is reduced thus inhibiting the oil’s ability to help the lifter to rotate. The viscosity of the oil must be selected based on the various bearing clearances rather than on what rings are being used on the pistons. Zero issues in regard to the oil viscosity with metric rings as long as the cylinder wall finish is correct for the particular rings that are being used.
