Have been using Mobil-1 since the car was new. Wondering about Royal Purple HPS which has more wear additives (zinc/phos) than standard API synthetics.

What's the opinion on it--better for the VQ engine??

I honestly think Royal Purple is all hype. I personally wouldn't pour any kind of motor oil into my car that has colored dye additives in it.

I also have yet to see any concrete proof that Royal Purple's products are superior to Mobil 1/Valvoline/etc.

The oil test generally show that Royal purple is superior to every other oil on the market.... until you go over the mileage, the RP literally turns into ****!! So if you're religious about your oil changes than yes, RP is the way to go... But if you're like 90% of maxima owners and always go over a bit (lets say 1k miles) then your motor will regret it.

Try that 0w40 Mobile 1 stuff, I've heard very good things.

Thanks--I think I will stick with Mobil-one for now, esp since the Royal Purple is almost $10/qt!
