Is this stuff as good as everyone says it is? Just watched Horsepower TV and on a 00' LS1 Camaro base HP on dyno was 302, after oil,gear,and tranny fluids were switched to Royal Purple, the dyno reported a 8hp gain up to 310hp now. Thats not bad if it works on every vehicle, and not just the sports cars.

Supposedly, it does keep temps down. I don't know if it will give that much HP on our cars, but I'm sure it will help things last longer.

they probably had walmart brand oil, then put in royal purple. So, Mobil one is still the best.

That dyno data can be normal variation. You need to average at least 10 dyno pulls before and after. So many variables, it'* nearly impossible to tell if the Purple is responsible.

I don't trust it in the slightest. I mean heck look at what happened to the other guys claiming wild things other than "meh, its oil" :

EDIT: A summary for those of you who don't spend 9hours of your day reading FTC demands of oil companies

Every one of these companies was ordered by the FTC, after review and analysis of claims, to cease and desist all claims of:

1. Improved fuel economy
2. Improved cold-start protection
3. Improved acceleration or power
4. That they contain superior chemicals that allow such claims

Some got more than others but thats the basis for all of them.

AMSOIL did a dyno test of a bunch of different oils. Of course theirs came up as best (which I ignore) but its interesting to note that Royal Purple was rated 7th place.

Zmax is the worst of them. Colored mineral oil. The FTC is throwing the book at them.

Where is Penzoil in that list?

Pennzoil is OIL. Why would it be on that list?

Isn't that owned by Quaker state?

Because that is what I am interested in, and really didnt read any of those long *** articles. Just read the summary by Dr.Jay
Here is the link on what I am talking about....
