ROYAL PURPLE
So I saw something on the Internet and it HAS to be true right?! Long story short someone said that royal purple engine oil made their oil pressure Jump up to about 60 from 40 while driving at 60mph. Anyone have experience with this? Is this complete crap? Or is this oil actually worth it?

Its possibly but warning I've had a few customers actually have engine problems while using this oil but I've also had customers who love this oil but never anyone with higher oil pressure!

I know a lot of people who use it from a DD to several Top Fuel dragsters who run it in everything. I have never heard of any issues with it for any apps, well maybe other than price.

I always thought it was an overpriced gimmick. brand of motor oil will not increase your oil pressure near as much as viscosity. I'm out before the pressure vs flow lecture.

And, for what it's worth, Royal Purple has always seemed like a marketing gimmick to me. Their site doesn't even have any technical data! If I was spending that money it would be on AMSOIL.

+1 to the whole thing. Also of note is that a new clean filter will increase the amount of pressure shown on the gauge. Especially so if one goes from a cheap clogged filter to a nice low-restriction unit. Just changing out a clogged filter to a new one of the same type can result in a change of up to 8 PSI.

Mainly issues such as loud lifters and engine knocks like the oil just isnt doing its job pretty much (Yet No damage was ever done to these vechiles) I worked at advance for a few years and have had numerous complaints of this! Even one of my co workers put some in his trans am and wow i thought the engine was surely done for it was making a loud noise from inside by the bottom of the block ( Never figured out where) but he changed the oil and never heard it again. Im not saying its a bad oil its just honestly not worth the money. I say shell rotella t is always the way to go!!

Well it does not happen to everyone hahaha!! I'm guessing certain engines don't take this oil well and maybe some do but as stated I'm not trying to make the oil sound bad at all some people say it does good for others not so good.
