+1...... that is what I did, but any quality oil made for the application you're using it in will most likely work just as well. Many here have proved it.

i have ran HD oil, amsoil, and mobile 1.
out of the 3 the mobile 1 came out cleaner, reduced engine noise, and the bike ran cooler.
as for primary and trans, i ran the HD forumla+ at first, then after reading some on the forum here, i decided to make a switch to redline primary fluid, and the redline shock proof trans fluid.
i will be putting redline in the trans and primary from now on.. the bike shifts smoother, less noise in the trans and primary. the redline is a good product.

Lots of Amsoil haters out there and as far as I'm concerned they are all talking out their ***! I've always had excellent results with Amsoil 20/50 in the motor. Combined with a HD oil filter and changed every 5000 miles it has always done everything I've asked of it and there are times when I ask a lot. My bike's normal operating temperature is about 230° and it has hit 300° more times than I care to remember and it has never been "black as tar" and/or "thin as water". When I drain it, it has never sparkled with metallic debris and there is very little shavings on the magnetic drain plug, if any. You guys can talk all the **** you want but Amsoil has made a believer out of me and has EARNED the right to be used in my bike.

OK - you opened up a can or worms (or oil). There are as many opinions on this topic as riders. The biggest thing is do regular maine.
I personally use Amsoil 20W-50 in engine and primary and Amsoil Severe Gear 75-110 in the transmission.
Amsoil has done a certified outside laboratory ASTM testing of various motorcycle oils under different conditions. Take a look at that to make up your mind.

I think the change interval is almost as important as the oil. Interestingsly every study I have seen compares new oils in 99% of the tests. I would love to see which oil does best in wear and friction tests after 1500 or 2000 miles.
My brother is the "garage" guy on the TV show Motorweek. They did a 100,000 mile test of Mobil 1 in a fresh engine. When torn down at the 100K mark and all parts mic'd, they could find zero wear. Of course this is 4 wheeler oil, but still says a lot for the new synthetics.
Personally I run M1 20/50 in the engine and primary, and M1 70/90 in the trans.

I figured this thread would spark some debate and the opinions of which is preferred. That is why I spent most of my evening reading the oil thread on the main page, then decided to post here where the mile loggers are. I thought this might spark some debate. I was just curious what the touring guys thought. Looking forward to swapping the fluids to see if I can tell any difference. For this go-around, it will be Mobil products in my scoot.

I agree. Switched to Redline at 1000 mile service. It couldn't get any better than with the Redline products in the trans and primary, so why switch??? As for motor oil, Redline, M1, Amway, Schaeffers, etc, etc, all good oil and probably doesn't matter which one you use. As long as you change like you are supposed to.
