Royal Purple

[Dave S 2]

OK Rodger, I finally broke down and went the Royal Purple way. But not in my Trac, my GSXR1000.



Was at O'Reilley's getting a K&N oil filter (yes, they sell motorcycle parts also), although I wound up with a WIX filter, I look over my shoulder and see the 1 gallon RP on sale for $20. I did the deed. Price was right so I bit.



Looks real nice in the sight glass being all purple n stuff. I know it will darken but I'm anxious to see if I can decidedly see or feel a difference in the bikes performance. Even if not, now that I think about it, the Trac needs an oil change within the next few hundred miles so I'm supposin` I should go back and buy a few more gallons for the $20 price.



Anyway, I forwent the Castrol synthetic I usually use in the bike and it was cheaper too!!!



Just commenting Rodger, figured I had to yank your chain since you are such a proponent of the RP.



So, how many miles can I go between oil changes with the RP in my bike? Keep in mind, it redlines @ 12500rpm...Although, I only hit redline maybe 4 or 5 times a day!!!:lol::lol:

OK then, a new post it is...

Forgot to mention, the RP was SAE 15W-40

15W-40? I thought that was for diesels...

Front of the jug states "High Performance Motor Oil for Diesel and Gasoline Engines".



Go figure, both "motor" and "engine" in the same sentence.



I've always thought of motors as electric and engines being combustion.



Guess it's the A&P comming out in me.

Dave, This info. is found at the links below. FYI, I found it interesting that one of the local Ford dealers was getting so many requests for Royal Purple that they are now carrying it.



Almost forgot that as long as you're not yanking anything but my chain, we're good. :lol::lol::lol:

Max-Cycle is specifically formulated to significantly improve motorcycle, ATV and snowmobile engine (and transmission) performance. It's recommended for use in both air-cooled and liquid-cooled 4-cycle engines and it's compatible with wet-clutch transmissions.



Formulated with select synthetic base oils and Royal Purple's proprietary Synerlec additive technology, Max-Cycle provides unparalleled film strength that is up to 400 percent stronger than the leading synthetic and mineral oils. Its shear stability and oxidation resistance promote greater performance and protection.



Independent Test Lonview Inspection conducted a test to determine if switching to Royal Purple's Max-Cycle would reduce motorcycle operating temperatures.



Conclusion Switching to Max-Cycle throughout the motorcycle reduced engine operating temperatures from 24 to 44 degrees F.



Read the full report: Longview Inspection Report (.pdf)



Synerlec greatly reduces engine wear - including ring, cylinder and bearing wear. It continuously adheres to metal surfaces, even after shutdown, to provide instant protection at startup until a full fluid film can be established.



Max-Cycle exceeds API / JASO new warranty requirements and is compatible with other mineral and synthetic motor oils. No flushing is necessary prior to use. It's available in 10W30, 10W40 and 20W50 viscosities.

The only thing I can think that you need to be careful of is the bike has a wet clutch and uses the engine oil for lube. A lot of car oil has extra friction modifiers that will cause your clutch to slip.



That being said, I've been using Rotella T (dino) for 5 years in my SV.. and in my wifes Ninja, with no issues and Rotella is also a "Diesel" oil.

Thanks Rodger, interesting read. With the cold weather approaching, my riding days are numbered. I don't ride too often when temps drop below 30 deg so I'll probably only put another 1000 or so miles on it. Then fresh oil in the spring. I'll then switch to the cycle oil. Most likely have to go to a bike shop to find it and I'm sure it won't be on sale for $20 gal. I'll most likely try their chain lube as well.



JD, you're scaring me man...Never thought of the friction modifiers in the auto oil. I'll have to pay particular attention to the clutch performance and rpm's now. Hopefully won't be a problem but one iota of noticeable slippage and it gets drained!



Thanks for the input,

Dave S.

Dave, Send a email to RP with your concerns. They will respond to you.

 

[Jacob Dryer]

Dave it's not a huge deal, just something to pay attention to, like you said if you slips just drain and replace with something else.



I know of plenty of bikers that use auto oil, it just depends on the brand/type.
