The only reason you are not supposed to run car oil in a motorcycle is because of the clutch. Certain synthetic car oils have certain "friction modifyers" that destroy a bike clutch. That's exactly what happened when I ran Royal Purple in my bike. Ever since that day I've been running Mobil One car oil 10W-30 in all my bikes. Mobil One does not have any of the nasty friction modifyers that destory a bike clutch.

so maybe you should use the right oil for your application instead of ripping on an oil that wasn't designed for what you were trying to use it for. just my $.02

You might want to go back and read the part about engine failures running Royal Purple. That stuff has the consistancy of water. The fact that it doesn't even have an API rating should scare you enough. But what the hell, it's your car. Do what you want.

i dont see any thing in this thread about engine failures and Royal Purple so i dont understand where you are saying i should go back and read... i just called royal purple to ask about the API rating and to get some answers about that but there is nobody there for tech support over the weekend. i will call monday morning and see what they have to say about API ratings.

Greg is right about engine oil lubricating the clutch on bikes. But this is the first time I've ever heard anything bad about Royal Purple. Mine never looked like water when draining into the oil pan. And I change my oil when the car is hot. And even after 20 minutes of draining it still draining out of there like hot syrup not water. So I would have to see some hard data on RP being the cause of engine failure before I would seriously question it. Until then it's just another opinion. Not only that Greg but I've been using it for the last 10 years on my Lincoln Continental and my Mazda 626 since they were new and they both have 150,000 miles on them now and they run great. So as far as it being crap! I don't know. All I have to go by is the last 10 years of using it. And 10 years of consistant use is enough time to know if it's garbage or not.

Just checked out Royal Purple's website and apparently they now have API ratings. They didn't used to and always were raked over the coals for it. Good for them finally getting some ratings on their oil.

As far as engine failures, like I said previously, many sportbike racers around here experienced engine failures using Royal Purple. Now, this was like 8-10 years ago and back then the non-API rated Royal Purple had the consistency of water. I haven't looked at the stuff since then. Maybe it's improved ??? I'm a Mobil One man, have it in everything I own........... even my lawn mower.

There's nothing wrong with Modil 1. It's good stuff. Hey Greg is Motul still widely used in sport bikes today? The last time I had a Rice Rocket was in 1993 and it was very widely used and was $11.00 a quart even back then. I went on there website and their still there. And still very heavily into the sport bike and race car business.

Yep, all that motorcycle oil is ridiculously expensive and they still try to scare you and tell you that you have to run motorcycle oil in your bike. As long as the car oil doesn't have any goofy friction modifyers (like Royal Purple), it's OK in your bike. I've been running Mobil One 10W-30 car oil in my bikes for 10 years now.

Chris_32212 · 10-19-2008

well i am running Royal Purple (in the engine only) and have been for about three months. i drive my car hard very often. if and when i get pulled over in it next i will explain my driving behavior as part of my routine maintenance to remove carbon build up. lol. seriously though, i intentionally run it hard for that purpose and i have not had any issues. The oil pressures were unchanged with the switch to royal purple and i haven't noticed any ill effects. i am concerned about using it in the ZF transmission though and i probably wont unless someone has used it without any problems. i will use the RP 140w gear oil in the rear diff though as i got confirmation from someone running it without issue in their Z.

I've found a couple of websites on them with all the specs and API ratings and testamonials. But they look like they are designed for racing only. Not daily drivers.

i also know that royal purple makes more power because of its abillity to reduce friction. so these friction modifiers that i honestly have not heard about before, probably caused the clutch on your bike to slip far too much which (and im guessing here) is maybe what caused the clutch to fail in the bike. but the friction modifiers might likely be what allows for less friction in the motor which has the direct effect of using less power to rotate the internal components. using less power to rotate the internals results in more power available for other things. like dropping panties. lol. sorry, couldn't resist. lol.
