Use Formula + in the primary...I just don't want my clutch to be too slippery. Use gear oil in the trans...If you have been using the same oil in all 3 holes, you will notice how much quieter it shifts with a heavy gear oil (75W140).

 

The 75w90 or 140 will go 15-20,000 miles in your trans. Both are unaffected by cold weather as both are 75w when cold and one is 90w when hot while the other is 140w when hot.

 

i use amsoil synth atf in the primary..70/140 in the trans..been doin this for a few years now..works great for me...

 

I usually leave it in that long....it will be a while before i change it...Just had the Primary and tranny opened up for the Inner bearing...I still might go to 90 next time or Redline...Not sure yet..

 

The indie that just did my cams swears by redline in the motor and lubrication engineers in the primary. I've been using mobil v 20w50 in primary and motor. Think I'm going to stick with non synthetic in primary. 75w140 mobil in tranny.

 

I have only changed my oil only two times. Once very sucessfully about 5,000 miles ago and (*&%#$*&) today. I had just got back from a 70 mile ride before I started and let it set for about 20 minutes to cool down a little, but it was still warm. Then then drained the oil.

I have a 2007 softail and use Mobil 1 synthetic. So I drained the oil with the filler plug out and I replaced the oil filter just like before. Last time I put in 3 quarts and it was a tiny bit on the full side. Today I put in 1 quart and started to put in the second quart and it has full up into the filler neck. Hmmm?

So I took a nice slow ride around the block and checked the oil level again....Way, way full and I can see the oil just below the filler neck. So I rode it to the gas station just a mile away and back and the oil level is the same... Way full after adding only one and a half quarts or less.

It would seem that all the oil didn't drain out? When I pulled the drain plug I let the pan drain for ay least 10 minutes intil it stopped draining and some of the time I was on it to hold the bike vertical some more might drain out. I pulled the filter like last time with the bike on the kick stand so it would also drain out. Not as much came out of the filter hole as I remembered last time, but I did let it drain over 10 minutes.

So do I just ride it and frequently check the oil level? Any suggestions are appreciated.

 

If I were you I'd check your tranny level... If your engine oil is almost a guart over full, after only adding a guart,,, well you do the math..
Either way --DO NOT-- drive with that much overfull, drain some out. Your oil pump, seals, and your air filter will thank you for it.

 

I would go to your local high volume parts store and ask for Mobile1 20/50 V-Twin oil in australia.......Easy to get around the world....

 

Sounds like you didn't bother to read your owners manual (it shows you where the engine oil drain plug is located), but instead drained something other than the engine oil...the trans perhaps. DON'T ride the bike till you figure this out!

 

In my case, my local indy shop stock Syn3 and amsoil, I chose the amsoil. ifyou want to use redline and it is readily available go for it, if it is going to be a problem finding it, you might want to consider another brand. In other words use what you can get constantly.
