I run a bottle of that with the Royal Purple HMX 5w30 when I do my oil changes.

I can say this.....the lifters stay quiet and I have none of the oil loss the most owners have.

Ive been using the Royal Purple HMX 5w30 on my Tahoe(78k), Yukon(201k) and Colorado(119k) because its a high mileage performance oil that contains extra zinc and phosphorous which really helps the cam bearings and lifters.

I have been running RP in my Colorado since 31k (prior to that I ran Mobie1 from new til the switch), when I removed the cam/valve cover last summer is was spot less; no sludge and the cams lobes looked great

Not trying to bend your arm into switching, just letting you know what I've found/experienced
