Has anyone used the Royal Purple brand in their bike yet? I have used their oil and filters before in my truck and it is fantastic esp. the filter cuz they are the toughest out there by far. I have heard bout Amsoil from others on badweb but nothing bout this one so I was just wondering. | ||

I used it in my racebike back in the mid 1990's. I had a case of the stuff as part of my sponsorship by a local shop. No complaints about how it worked. | ||

here is the link to there website on the oil in relation to wear on the cam chain tensioner. http://www.royalpurple.com/motorcycle-oil.html | ||

Last I heard Royal Purple adds a friction modifier, this is a no-go with a wet clutch. But I may be wrong, everything else I have heard is they make a good oil. | ||

Not likely to find friction modifier in any W40 or W50 grade multi-viscosity oil, let alone a synthetic oil. So-called friction modifiers are energy saving additives that are only found in automotive oils in the W30 or less viscosity grades. We need not worry about them in W40 or W50 grade engine oils, since those oils cannot meet any kind of energy saving criteria and are not specified for use in any new automobiles. | ||

I use Royal Purple in the XB. 10W40 in the case, ATF in the primary (slipper clutch needs synthetic ATF) I change fluids every weekend (about 200 track miles) - but haven't had issues. Send RP an email - they WILL respond! | ||

I have used it in newer cars and my bikes with no problems on wet clutches and It is good oil.I did put it in my '84 GPz1100 that had been sitting for about 10 years when I got it and it leaked alot so I went back to dino-lube.Still leaks a little but not as badly.No problems in other engines | ||

I use it in the X-1 in the Summer. Seems like good stuff to me, if you need a high viscosity oil. | ||

I use it in my 1125R and my Uly. No problems and clutch operation is fine. | ||

I used to use it in my Ducati, and it actually helped the bike run 5-10 degrees cooler than other synthetics I used in the past, that was the 20W50 Max Motorcycle Synthetic blend. | ||

Has anyone actually done an oil analysis on the RP? I've used this stuff in my Subies a LOT...the problem I'd run into is that my 5w30 would turn into 20 weight in a matter of 1000-2000 miles. Granted, these are turbo engines, but motorcycle engines are still demanding on oils, especially the air cooled ones. I'd be interested in seeing some post-use data as I've contemplated ordering this stuff for the XB. | ||

1324 - I haven't done any analysis on it, but there is a local BMW guy who did after 10000 miles of use (changed the filter at 5000 miles) and the analysis was... ---- I ran my oil ten thousand miles, changing the filter at 5,000, and had it tested at 5k and at the 10k change. Lab said oil was still within spec, both times, no significant wear indicators in the analysis. ---- This is on a 1200 boxer engine. | ||

Thanks for the info. I'd be interested in seeing results if you do an analysis! | ||

I had asked a couple questions about the XB - 10W40, slipper clutch (synth ATF) and if they had an oil filter - next morning got the following:

Good info. I happen to have a few quarts of Max ATF on my shelf in the garage. If I can find someone who has successfully run this stuff, I'll give it a shot. Fortunately for me, I find the Formula+ to be sufficient. But, if I can improve, why not... | ||

I posted links to a bunch of oil testing and analysis information on another thread. There are a lot of good test results for many different oils including Royal Purple and the linked articles are definitely worth reading. http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=290431&post=1664834#POST1664834 | ||

Good information, thanks for doing the leg work. I know all too well how hard it is to extract meaningful data out of 'independent' tests, random oil sample reports, etc. Speaking from experience, every engine does something different to the oil. Some are easy , other are hard. To make matters worse, the lubrication industry is VERY tight lipped about oil compositions. Many people would be very surprised to discover that most of the OEM's don't even have a good handle on what oil works the best in a given situation. Case in point, a very well known OEM contracted my company to do development of an internal engine 'system' for a few of their engines. This manufacturer endorsed/recommended/supplied a specific type of oil in their complete lineup. However, our extensive in-house testing confirmed that this specific oil was actually causing more harm than good. It's hard to stress the magnitude of this discovery since I'm masking names here, but trust me...it went completely against conventional oil wisdom. To this day, the mystery remains unsolved except for knowing the results. Cooperation from the API, the lubricant supplier, etc. was nonexistent. We were more or less told "The oil contains additives that, blah, blah, blah." No honest technical content or guidance. I fully believe the industry is against providing knowledge to the 'public'. So, sorry for the long-ish story, but the experience I had was very fitting. I am very cautious nowadays when it comes to selecting oils... |
