Royal Purple?

Does anyone run royal purple oil / and do u see any real benifits from it. Some say u can increase ur hp slightly just by using royal purple fluids?

Don't use Royal Purple...some of the biggest crap ever made, along with Weapon X Spark Plugs.

Sarge made some threads awhile ago with studies done with the top 10 oils and Royal Purple did the worst in almost all of the tests (heat disipation and wear factor). Do a search and you should find them.

Royal Purple also took a hit for false advertising not too long ago: http://www.corvetteactioncenter.com/...vertising.html

royal purp is way overrated. stick with mobil 1 5-30. but i will tell you they make really good diff fluid.

Royal Purple = Aunt Jemima


:true:

Mobil 1 is fine. But overpriced.

Pennzoil Platinum 10w-30 is the best cheaper off-the-shelf synthetic oil for our cars.
$20 for 5 quarts at Wal-Mart. I think the one by my place actually had it down to $19 last I saw.

Wait I felt a disturbance in the force Sarge is gonna get you.

OP Sarge has made a thread on the matter "I'm an oil Junkie" Tons of info.

I've run 10w-30 the entire life of my car :dunno: The 5w-30 is more then likely to get a higher MPG out of the meaty LS1 from GM :shrug:

A thicker weight is better for engines that are ran a little harder than others.

Last time I ran RP was 2 years ago.....then went to Pennzoil Plat and now Amsoil after the H/C

Sarge has covered this before as have I. 5W-30 and 10W-30 are both the SAME thickness at operating temp. The difference, 5W is a little less thick at cold engine start-up than 10W.

Personally, I use 0W-30 so that I get optimum oil flow at cold engine start-up while still protecting as well as 5W-30 or 10W-30 motor oils when the engine is warmed up and under load.

Let me put it this way, the 30 at the end of 0W-30, 5W-30, and 10W-30 means that all three oils have the SAME thickness or viscosity at engine operating temp.

I have used Royal Purple exclusivly in both my 01 Z28 (Sara), and my 04 Tahoe, and have had no issues whatsoever. I purchased 5 cases when the price was around $4.30 a quart, and I have enough left for 2 more oil changes. The price is way up now, around $8 + a quart, so I am planning to change brands of oil. I am going to try the new Castrol "Edge", and keep the same weight @ 10W30.

I change my oil every 10K.

Sorry never seen your post or Sarges but that is good to know. I will be switching next oil change for sure. :true:

I RAN the purple 10w-40 till i sold the z, never any issues. changed every 5000 ran a k&n oil filter also.

Pennzoil plat or amsoil...period do not differentiate or even think anything else
