Why Not Mobil 1 V-Twin 20W-50 in Tranny?

Harley recently revised their transmission fill procedure, instead of pouring in 32oz, now you start by pouring in 28oz, check and add more if needed to avoid overfilling. I believe this is because Harley has recognized that more and more people are using a heavier oil which, even when hot does not drain as completely as a lighter oil.
Harley says you can use SYN3 simply because of the convenience of using the same stuff in all 3 holes and just so happens to be their most expensive oil... go figure.

saw a thread on here some place that said the syn oil in the primary was over kill and the syn was not good on the clutchs [ to slick ] and the oil in there is more for cooling than lub and recomened the formula + its cheaper , I switched it in mine after a clutch replacement and works great , smooth shift and easy to find nut.

That would be for pre 07. Correct?

Then finally they introduced Syn 3, ( currently about 60% Dino 40 % True Synthetic.)
Just cause somebody from MoCo says it's so, doesn't necessarily mean it's so,............. or best for your bike. There's much to learn on Forums like this.

well,....im at a 1000 mi. breakin, ive decided on all Syns. Amsoil motor, (20 /50), royal Purple Max gear in Tranny ( 75w 90 ) and Se Syn 3 in Chain Case. Ive Talked to alot of riders and maybe the Syn 3 is a little overkill compared to F+ but im kinda sold on synthetics . I was goig amsoil in all three but alot of people say you need the Gear additives for Trannys

The thing I don't understand is guys wanting to argue about not needing that much protection.
You bought an expensive bike. Why skimp on oil?
Redline Shockproof heavy is a differential oil that has the sulfur content. Being a 100% synthetic, it pours like a 75 weight oil, yet PROTECTS like a 140 weight oil. Why not put the BEST in your 20 thousand dollar bike?
On the primary, any standard 10W40 will do. I "spoil" mine and put Redline Synthetic PRIMARY oil in there. it is synthetic (which isn't necessary) but is made specifically for a Harley primary.
For the engine, I use Mobil1 15/50. I like friction modifiers in the ENGINE.
Synthetic is simply using technology to your advantage in a bike that operates at a much higher temp than more modern water cooled engines. They don't break down under high heat like a regular conventional oil will. Because of this, you can go farther between oil changes.
That said, dirt still gets in there....so for me PERSONALLY, I look at the oil on the dipstick, when she has some miles on her, and the oil looks dirty, then it's time to change it, if only to get the dirt OUT.
It frankly makes no sense to spent a ton of cash to buy a bike, and then penny pinch on items to make it last.
