I put RP in a manual transmission, I did have better shifts during the coldest days of winter, but it sheered down to liquidity water in 30k. Just wow.

I've used M1 since the late 70s and have always been pleased with the performance, especially after all the miles I put on a vehicle.
That's my story and I'm sticking with it.

I've actually used Royal Purple engine oil so I will limit my answer to just gear oil.
Many scooter guys swear by Royal Purple gear oil in the final drive.
I use Mobil 1.
I honestly don't see Royal Purple providing any protection that the less expensive Mobil 1 doesn't. The wording in the manual says you can use either engine oil or gear oil. If engine oil will protect it, gear oil should be fine. Either way it's just a few ounces a change so a quart will last a long time

Any approvals for VW, MB, BMW? NO, and it is not expensive to get one, granted if it can meet their specs.

Because the local car store here sells it for $95 for a 5L jug! Crazy stuff
I've come to love M1 EP oil and M1 0w-40, pretty sure I'll never stray from them unless they went up drastically in price.

Make a synchomesh gear lube?

Why pay twice as much as Mobil 1 0W40 that performs so very well in my V-12?

Do you get a fleet discount on insurance?

Wasn't RP used on "Pimp My Ride?"

Unless it contains unicorn blood (and the VOA's I have seen indicate that it does not), there is simply no reason to pay the premium for RP over other comparable API approved synthetics.
I'm sure it's a perfectly good oil otherwise

I've run their power steering fluid, gear lubes, and purple ice and they performed OK for me. But their gear lube didn't prevent the outboard axle bearings in my Camaro from wearing out in 50k miles. But neither did Red Line.
Just haven't gotten around to running their engine oil in the Camaro, and probably won't because I've got about a 2-year stash of Pennzoil. If I did run RP engine oil, it would probably be their High Mileage stuff with the Synerlec additive.

I've run RP before, don't really hate it -- but when this is the entirety of their "product sheet", it is hard to get excited: http://www.royalpurpleconsumer.com/wp-content/uploads/PS_HPS_Motor_OIl.pdf
It has nothing useful in it.

Bought it once on sale, $49.99 for 5 qts and filter; a savings of $40 according to my receipt.
Put it in the car expecting to run faster and jump higher because it had Synerlec.
It ran like, oil.
Then I found that is wasn't API certified or something and I was still under warranty. Not good.
Then this boutique company was bought by Camulet.
Then it became API certified, SN; which meant the zinc and phosphorus were taken way down and I started calling it Syner-lack or RP Lite.
The racing version or HPS still has the higher level of Synerlec, it's what we remember, but it can't meet SN standards.
