I know RP usually gets a strong reaction here, but I'm just curious what people think of RP now offering a 0W-40 grade. Spec-wise, it looks almost exactly like M1 0W-40, so we know what they 'set their sites' on in developing the oil. Take a look:

http://www.royalpurple.com/prod-pdfs/motor-oil-ps.pdf

In a way, I don't understand this move, as they already have a 5W-40 grade, although it is a fair bit thicker. Would make more sense to me to invest in a 0W-30 grade, as their 5W-30 has lousy cold-pumping numbers....
 
I didnt know they made a 0w40. Looks very similar to M1 0w-40 on paper. It's probably a good oil I'm sure. RP's claim to fame is Synerlec, their proprietary ester based AW additive.

I also never realized that RP oils all have a 11-12 Tbn.

Hmmmm.....

I first 'heard about it' when JohnBrowning came on this site a few months ago bragging he had managed to get a free case of it for 'testing'. People criticized this move, and I haven't seen much of him since....

RP only just updated their PDS to show this oil, and I haven't seen it in the stores near me that sell RP, so its just trickling into the market now.

I 'suspect' it will behave just like M1 0W-40 - shear down to a high 30-weight after a short time in service, and stay there for a bit. Looks like a good oil!

Yup. Mostly SL with a couple SM
 
I`ve got their 15W40 in my car right now for my winter fill (I usually use a 20W50 most of the year). All I`ve got to say is that so far it`s a smooth running oil! I used M1 15W50 for years,but it seemed like it started to run a bit sluggish. I tried a few 20W50s and Valvoline VR1 was the best of the bunch. My car pulled like a beast with that oil. Same thing with the Royal Purple 15W40........coming home from work today I did a 3rd gear pull and swung the rear of the car sideways. So far I`m really impressed! Next summer I`ll be trying a sump full of RP 20W50 and see how it goes.
 
I used the RP 5W-40 from 10k to 30k in my Pilot (on a bet with fellow mechanics who were disapointed when it didn't self destruct) and had good UOA results.

I was going to start using RTS 5W-40 in the Civic at 210k because it is still using about a quart of SSO every 3k like it did with the RLI 0W-20. But I may try the RP 0W-40 for the next 10k and then the RTS 5W-40 before going back to conventional oils.
 
I found out today that my local NAPA store is carrying Royal Purple. There was 5W30 Royal Purple there. I did not check to see if it was SM rated.

If I used it I would have to change my ways and change oil once a year or at most twice a year. I would probably have to go once a year and just adding oil and changing oil filters when necessary. My car does not leak oil. Would it be worth putting Royal Purple in a car with almost 70,000 miles?

If you have an O`Reilly`s there,they usually sell RP for about $1 less a quart. Napa`s always more expensive here than any other auto parts store here.
 
In N CO its at every autoparts store except Carquest. If you order online partsamerica its 1$ cheaper/qrt too. I use it in the EVO, just about all its ever had.

My local Walmart carries RP 5W-30. It's rated SL. The price is $6.72 plus tax.

Some Wal-Marts do carry RP. However, they are not an authorized RP retailer. They are getting it some other way.

To be fair, he did state those two facts as separate statements.
