How good is Royal Purple Oil?

[20ducks]

Going to change oil again soon. My neighbor asked me why I use Royal Purple Synthetic? I have been using Royal Purple for quite a few years. But, I couldn't remember why. Will someone help me with a good response?

Seems odd to use a particular product without being able to justify why you use that particular product.

Because you like to pay extra.

Royal Purple was a better product when it first came out, but after they removed the Sinerlec, ZDDP, Moly additive packs due to catalytic converter issues, it isn't any better than all the other stuff you can buy at Walmart. They do still make a "racing oil" with those additives called XPR, as well as a street car version called HPS. Neither of which are "recommended" for vehicles still under the factory warranty.

Seems like you bought in to their marketing.

It's probably not 'bad', but It's not cheap. I've never seen it come out on top in any of the different motor oil comparisons I've seen.

Most of the well known oils meet or exceed expectations of manufacturer. I stick to Motorcraft synthetic blend and never had any issues with any Fords. My previous Coyote ran to a healthy 130K miles, not burning any oil. I am sure some Oil analysis freaks will be swearing by different oils.

Yeah...odd.

For a full synthetic, what do you recommend?

LOVE Walmart. Bought two 5.5 liter jugs of Pennzoil Platinum Euro 5w40 for $60 CAD. I would rate the platinum as the TOP oil one could buy.

Anyways RP is all hype. MOTUL if you really wanna be different.

Depends. If you are just looking for something off the shelf- really any full synthetic 5W-30 will do. If you want affordable, go with the Quaker state Ultimate durability 5w-30. Every Walmart has it, and its like 22 bucks for a 5 gallon jug.

If you can wait a day or two, order the Pennzoil Ultra Platinum from Amazon or Walmart. None of my local stores carry the Ultra Platinum product, but maybe yours do.

Personally, I like to run a 0W-40 or 5W-40. Motul, Penzoil Ultra Platinum SRT, Mobil 1 Supercar, Liqui-Moly, Castrol etc.

These motors really aren't that hard on oil (not talking about forced induction or E85) So if you are stockish, Just run a synthetic 5w-30 and change it every 4-5k.

Liqui Moly ...does it rank up there or ...

Nothing wrong with good old Motorcraft Full Synthetic 5W-30. That’s what I use in mine. Otherwise, anything that meets or exceeds Ford’s spec is just fine.

Sure. If its good enough for Porsche, Im sure its fine for Ford. It is pricey though.

There is no such thing as a "Motor Oil Expert" on this forum ,or any other. Everyone has opinions, hearsay, taste tests etc. but really it's 99% opinion.

You can run anything from 0-20 all the way up to 5w-50 depending on conditions.

My motor sounds a bit quieter and slightly smoother when I run A3/B4 spec oils (european standard) but aside from that, it honeslty doesn't matter nearly as much as changing it frequently (4-5k, or less if running E85 due to fuel dilution and moisture)

In Illinois, I'd be running a 0w-xxx in winter for easier start ups, but again, thats just me.

^This 100%. I have 14 years and 106,000mi on my 2011 5.0, all of which was run with good ol’ Motorcraft Synthetic Blend. Zero noises, zero problems, zero burning.
