Wow! What a blessing to see you out here again! Don’t mean to rain in your parade it some proper exposure is needed. While I can see what you’re saying as far as flow rate of a 10w40 vs a 15w50 (like I’m running, I’ve been riding in temps of 94-98 already. These temps start to “cook” an oil with a lesser viscosity rating such as a 40 vs a 50 made for higher temps.
I’d also like to present the following video which also mentions that Royale Purple is not a “true” full synthetic but is a “blend”.
Was it not “Race Hill Farms” who was touting the NEED for a FULL SYNTHETIC? He was also saying Redline, not Royale Purple.
Here’s a great test video putting Royale Purple (a synthetic blend) vs Amzoil (true full synthetic).
Hi Tony! How are ya? Been following your exploits, and you and the missus, are having a blast. Good go! I saw her postings on the public Facebook SVTC site. She seems quite active there... [IMG class=inlineimg]/forums/images/smilies/smile.gif[/IMG]
Tony...with watching your video example, I do believe that you came away with a few misconceptions, and I will go through them,
Firstly, Royal Purple Max Cycle (their targeted line of formulations, or as they call it, their 'blending', of a base pure ester synthetic with their proprietary additive package they call, SYNERLEC,) is absolutely a premium based full synthetic
. R.P. does not make a semi-synthetic formulation (or blend, as they call formulation by other brands).
If you thought this dude was claiming that by reading the word 'blended' on the back of the 5W30 automotive 'formulation', then that is where you might have been misled. Had he stated it was a semi-synthetic...that being a 50 percent conventional and 50 percent synthetic base, he would have stated that. That is, simply not the case. I have bottles of the Max Cycle 'formulation/blend' at home, and it is
a full synthetic, as is Amzoil or Redline. So, I needed to clear that up.
Also, this guy's test had no bearing on their line of targeted formulations for use in an air/oil cooling-solution, engine environment, which is in fact their MAX CYCLE synthetic line-up
. That and only that is what my post was stating and recommending to try out. Not an automotive 5W30 as he was side testing.
As to your concerns that at an outside ambient temperature of 90 to 95 F, that a 10W40 oil, could 'cook'...rest easy...for that is not the case. This isn't Mazola, we are talking about, lol....and in fact, if you read the formulation 'or blend' data of their Max Cycle, the hotter the base gets, the more the molecules double down, and create a more dense lubricity base...and I suspect that they use a high volume parts per million of Ester, to accomplish that.
Now, the main thrust of my post, was not that one uses this or that branded, premium 10W40, or whether one uses my recommendation and the very oil I have based my observations on, while running through my crank and transmission casings....but that the 113 C.I. runs ***BETTER*** with anyone's premium brand, full synthetic 10W40, than with any higher viscosity of the user's choice in brands. Tony...I wanted to see if I could reproduce the observances that Bill posted, and ABSOLUTELY, I could...and DID! He was on the money...for my 113 C.I. is reams more quiet in mechanical operation, than when running 15W50, or 20W50 that I had used and experimented with, last Summer. There is absolutely no metric comparisons in the tranny's operation, in ease of shifting the forks...and they moving the gears to mesh. Night and day...in how much more easier, smooth, silky...and QUIET...is the tranny operation with 10W40 running through it.
That is the thrust of my post...but I had to clear up any misconceptions, that you might have inadvertently injected. R.P's entire formulation lineup, is premium synthetic based, and they ADD in, or as they choose the word 'blended in', as in their ad copy,...they then 'BLEND' in their additive Synerlec package into the 100 percent synthetic base oil. That is the only reference of the word: blend....and again, not a 50/50 convention/synthetic Semi-Synthetic oil product. Needed to clear that up, here.

Whether one uses what I am using, and can vouch for what great performance it brings to the table, or one might go with Redline...whatever....again, the MAIN POINT, of my post, was about running a premium (your choice) 10W40 viscosity, and not a thicker motility choice.
For myself, Tony...I am getting now such great results with R.P. MAX CYCLE 10W40...that I will now stay with that formulation...and continue to enjoy the now quiet, silky operation of the tranny, as well as a much cooler running in the twin cylinder heads. All is good!
Tony, I would never steer you, or anybody else wrong....and I will absolutely state the following...if you don't try a premium 10W40 full synthetic...you are truly going to lose out, on the same observances that both now, Bill and I, have, concering our 113's, and will continue to promote as the premium engine and tranny experience. I am fully now (from my own experience) on Bill's line of Scrimmage
BTW, what did you think about my other 'good news'....that it seems we Canucks are getting that sorry-butted update within the next two to four weeks. FINALLY! FINALLY! Hope something arrives at your end as well!!!
