Then I would get royal purple and call it a day
Imagine the performance gains going from a car motor to a high rpm bike motor and running it through a transmission.
get ready and hold on tight

That's quite interesting information Jeff.


I think it is quite coherent with what I stated before about oil, filter and slip-on hp.

A few years back, when I was building engines for our sprint and endurance racing middleweight superbikes, Dave Rash (D&D) offered us a case of RP. We had been running Mobil 1. Back to back, on the same dyno on the same day with ambient temps within three degrees, the RP was worth 3~4 HP. We raced the endurance bike to second place (by just 12 miles) over the season of 10 races lasting from 4 to 24 hours. No problems. The sprint bike was just as successful although it was tuned for more peak RPM while the endurance bike was tuned for broader mid-range. None of the engines showed abnormal wear.

Just two data points, but that's what we learned.

Just to chime in I'm in the industry and have heard a lot about Motul's new 10w-40 called 300V being really good stuff. I'm definitely going to give it a go!

I think everyone should try several oils- for me it is all about shifting smoothness and clutch feel.


An extreme anti-mixer for oil posted this on a Ferrari forum, if you really want to be "neurotic" about any oil mixing:


"For the first oil change in my 575 Maranello I drained the Shell and put in 0W-30 Mobil 1. This was at a few hundred miles on the odometer.

I drove the car home from work, put it on the lift and drained the transaxle and engine oils. I also opened and drained the oil cooler and took off every line that is in the oil system.

I wanted to get every speck of the Shell oil out of there. For optimal results you are not supposed to mix synthetic oils of different brands.

The system takes 12 quarts with a “normal” oil change but took 15 quarts for this change. It all took about an hour. I then started the engine to check for leaks. The multitude of mechanical engine noises that followed nearly broke my eardrums for about 10 long seconds.

Then it was suddenly very quiet. You could hear a pin drop. There was certainly the most possible amount of surface oil on all the internal parts as the engine was only off for an hour. But it was not until the oil circuit primed, filled, then sent flow into all the parts that any lubrication was occurring."

I would like to see independent motorcycle oil testing (not published by Amsoil or some other company that wants certain results while hiding other results, such as leaving out Rotella and Red Line oils) that is newer than 2003. As far as I know, it does not exist.

The calsci.com guy does not think mixing oil is a problem.

The Cartalk guys also have the same opinion about mixing oil:

Mixing oil sounds like work. Just get a jug of Rotella T6 5W-40 or T Triple 15W-40 and call it a day.
