I run Amsoil. I do the preferred customer deal and it works out to around 8 bucks a qt. 20-50 in the engine, 10-40 in the primary and 75-90 in the trans. I actually don't disagree with those who stick with dino (standard fossil oil) It's just I've got this weird way with my hog and running amsoil just makes me feel better. I also may try Redline, my son runs it and likes it, and I know what is meant by the lifter noise... decisions decisions.

 

lmao whoops

 

Amsoil preferred customer, I'm all set! I have a friend who will share the cost of the membership and his bike runs water-cooled so he needs 15w40,we will each order our case of oil and cut the shipping cost in 2!!! CHEERS!

 

Well your last post seems like you believe what they say. Not using HD products will not void your warranty as long as you change the oil have your receipts and don't let it go to sludge. Screw paying $300 for a 1k or 5k service when all they do is read out of the same factory service manual you can purchase and your services are maybe $50. These dealerships only refer what they are contracted with and what they need to get out of inventory. As for service, it's just ridiculous the amount of money. You can probably change the oil in a diesel truck cheaper. Maybe the HD oil is a great oil, my dad has ran HD Dino in his FXR for 80k+ miles now and it's fine, but there is better oils out there. The fact that my sewing machine noise from the primary is gone, cooler or consistent motor temps, smoother shifts, easier to find neutral. I had the stock dino oil. Had HD do the 1k with SYN 3, bike seemed louder and not as smooth. Did my own change with AMSOIL at my 5k and will never look back. The difference is for the better and will be sticking with it.

And I was being sarcastic about bringing the back for warranty work. I was just saying you probably have a better chance of it listening to them.

 

Don't waste your money on syn!!??? The stupid HD dino oil is the same cost as syn! Arspicks i tell ya!
Become an Amsoil preferred customer and you'll never search any further!

 

I have switched to Amsoil. I have only done one fluid change. I like what I have read, and it is a choice that I am happy with, so I am going to stick with it for the entirety of the bikes life.

 

No, they don't. The latest recommendations on Syn 3 can be looked up on the Harley Davidson website - listed in accessories / Screaming Eagle or maintenance section. It used to say use in all three, it doesn't now... check it out.
Formula + weight? I don't know... use gear oil in trans (75/90 etc) and primary is chain case for heat dissipation and lube "no friction modifier" because of the clutch.
I run 20/50 in the engine, 10/40 primary and 75/90 in trans, all Amsoil. Your bike, your choice.

 

where does everybody buy their amsoil

 

For $20 you can become a preferred sealer and buy the oil a discounted price...i have ordered 1 filter, 1 case of 20w50 and 16 quarts of 10w40 and i think with freight it was $276.00...that included $21 ibn UPS and tax.

 

With hundreds of posts on oil...aren't you already beating a dead horse by just posting another one....simply 'asking for everyone's opinion'??
