Royal Purple Options

[rudedude]

I went to my local O'Reilly for royal purple 20w-50 last night and was I ever surprised when they told me the list price was $18.63 per quart! I was quite shocked when he rang up the 4 quarts and wanted like $75.00. That was with the 10w30 on the shelf for $7.29. The 20w50 was hiding behind the counter.
Any one else had an experience like this?
I was able to talk them down to 9 bucks but you know the price of oil is going up.
I don't think I am headed back there in the near future!
i do like the oil. In 2,500 miles last year there appeared to be no wear as evidenced by a nice clean filter when cut open and valves that needed no adjustment.

Just had to vent.

Royal Purple has finally lost it's crown after 5 years... What has proven to be more effective is only 4.50/quart! RP is still a great oil and I use it in all my cars, but will be swapping to the replacement oil at each oil change in each vehicle.

You can order Royal Purple off line at a good price, I buy it in 5 gallon buckets..

We'll be having a three part Radio Show on oils in June to share what has been found with different tests and extended run times with different oils.

Jake, Have you done dyno runs using differnt oils. I saw a test performed on another forum where dynos were done on a motor with several brands of synthetics all same weight. Mobile One sucked compared to Amsoil, Royal Purple and Redline. It was intersting to see differnce in oils in regards to hp. Being a born skeptic I wonder how much of this is just variation in dyno conditions, but still interesting. I'll try to find it and post to see if you have similar results.

I'm using Amsoil and it seems to work very well with my six on the track. My motor runs incredibly cool on track. I havent been able to get it over 180 degrees with Amsoil and my new cooler.

Of course, some dynos have variables, thats why I invested in the new lab and removed all user error with the implementation of digital controls and data acquisition sampling rates that don't allow for much less than perfect results. Even my old dyno was very accurate, I ran it so much (and still do) that I can feel the differences in an engine, or an engine oil or a tuning change right in the controls, the way the engine sounds and the way it even smells!

The new lab removes guesswork and provides a solid platform with temperature control of the fan and air intake charges easily.

To date we have not done very much testing of oils for HP at all, every time I ran a test like that I didn't see any differences, AND the oil is very expensive to purchase. The oil companies generally will not give guys like us a discount because they do NOT WANT the tests to be ran, else the secrets are compromised. The only exception to this rukle is the guys at Brad penn, Charles wrote them with some results and a week later a pallet of all flavors of Brad Penn showed up on my loading dock for evaluation and use in our F production engine as well as the "Blow it up!" build.

That being said, Charles will be coming down in mid summer for a round of HP and oil temp testing between our favorite brands of oil in the new lab... This will consist of both power pulls at different temps with different oils, but will also consist of literally baking oils on the dyno for extended periods of time at extreme oil temps (250-300F sustained) and then comparing the pre and post analysis samples as well as matching that to the data logs to find trends. My resident Engineer will be here from the UK for that bit of testing, thank goodness!

I will say that on my 3,450 mile trip last year, as soon as we dropped out test oil #3 and put in Royal Purple ( on the side of I80 in Nebraska) there was an immediate difference in the engine's smoothness. It was noted immediately by me and my back seat Engineer who looked at me in the rear view in total amazement and asaid "feel that?".... I replied "I told you so"....

Nobody ever believes us..........
