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.
