Go to O'Reilly!! Sure, there's no difference in the products because they're the same brands but at least at O'Reilly, you'll get waited on! And if the price happens to be more, just ask for a price match and they'll do it.

That being said, if by the slimmest chance you have a bad experience, any at all, let me know and I'll have it fixed! Yes, I'm predjudiced, I'm a regional manager for O'Reilly and I oversee 85 stores but 99.9% of the time you'll get better service with us.

.....I'm off the soapbox now......thanks!

 

Thats funny if HD does not suggest using in in the trans any longer why do all the Screamin' Eagle bikes from factory come with Syn3 in all three holes???

 

Why not use a heavier Gear Oil? just wondering why everyone is going only to 75W-90 and not 75W-140 gear oil? is the 140 gear oil too much for the tranny?

 

I hope you get an answer as I changed the tranny oil to Mobil 1 75w140 recently. I got to Auto Zone and forgot what to buy. They had both the 90 and 140, I went for the 140 and hope it won't hurt anything.

bump - anyone know if using a heavier gear oil will help or hurt the tran?

 

I'm kinda new here and been reading all these syn3 posts. I have a 2001 softail standard and I have been running syn3 in all three holes for over 35,000 miles and I have yet to hear any noise or problem from anywhere in the bike! At the 35,000 mile service I pulled the gearcase cover and had no wear on the tensioners. Used a small dentist mirror to check the upper/inner pad and it was OK too. Maybe I have an odd bike but it runs like crazy and I've never had as much as a peep out of it . Just the observations of one person. Also, the last post with the 140 gear lube seems to be too thick to me. I used to use it in truck trannys and rear-ends. That is not to say that any damage will occur as the truck trannys are built about the same as a bike tranny really.But I think 80-90 is better for your harley. Phil
Hey j2, on second thought, even truck trannys run 80-90. So I think maybe take the 140 out of there because when the bike is cold you may not get the proper flow of lube in there. Phil

 

Crap, I retardedly bought a sevice plan and it shows syn3 going in all holes for each service. I guess I will be buying the Redline and asking them to fill it with that...oh well.

 

If you drain your oil or tranny and find some material on the plug magnet, unless you can see a part number on any of the junk, don't worry..
