quiet and cool oil
Guys I have run amsoil in everything I own, but after reading some of the info here, i tried dino oil, tried castrol , and switched to Brad Penn,,,both were quieter in the valve train...then I noticed, the Brad Penn was running about 20 degrees hotter than my old 60 weight amsoil...so I tried Royal Purple 20/50 today and sure enough, very quiet motor and even cooler than my amsoil...Rough numbers were amsoil...noisy motor and about 210 highway oil temp at 95 F.....castrol had quiet motor, dont remember the oil temp...Brad Pen, quiet motor, but about 225 oil temp...Royal Purple produced a very quiet motor, and ran about 205 oil temp at 95 F.......your mileage may vary.......

205F-210F with synthetic oil is about right. I run Mobil1 15W-50 and I'm at 190F when moving in summer temp but I have an oil cooler so my oil is probably 15 to 20 degrees cooler than without it.
I tried Brad Penn out of curiosity 2 years ago and I flushed it after 200 miles. My clutch didn't like it at all and my engine was not quieter than with M1.
Anyway, the best way to run cooler is to properly tune the bike. Oil has nothing to do with it.

your numbers can have 2 meanings
a.) that the motor is running cooler
b.) that the oil is not removing as much heat from the motor internals
one is good, the other bad
c.) quiet can be higher viscosity- which consumes power, does not flow into and through all the motor as quickly and easily-
synthetic oil is more resistant to thermal breakdown- the oil in a Twin Cam is asked to do more than the oil in any previous motor. Non- synthetic is a really bad idea.
As it is sprayed at the bottom of the pistons and the cylinder walls it can crystalize.
I've had old motors with crystalized oil in the pan, it is like sand.
when testing temps the conditions need to be same for each test. temperature, humidity and speed- any changes in the air flow to the motor ( like vents open/closed)

I am just running stage 1 with fatshotz, and have never worried about my oil temp, but after looking at the royal purple web site, i saw their claim that their oil would run cooler than dino oil by about 25 degrees...so I had to try it and it looks like at least on my bike it is true.....

I would be happy with any of um, jst got tired of the valve noise with amsoil...and thought i would experiment....ran race engines on my mini sprint on amsoil for years, at 15,300 into every corner..never had a problem......

I'm an oil nut. I've got so many different brands and grades in my garage it's retarded. But I wanted to try all the heavyweights in my bike and see for myself,from experience,which reduced noise,how quickly the rpms hit and so on.
Royal purple and motul were the top dogs as far as noise reduction. Mobil 1 was the absolute loudest. Mobil was so loud it was like a can of marbles rattling. Amsoil v-twin 20w-50 was about the middle but if I substituted a quart of straight 60 and that helped quiet it down.
Of all the oils I tried pennzoil 20w-50 auto oil was the quietest. And it was also the cheapest.
Try motul next time. Great stuff
