I'm kind of cheap - I use Redline Heavy Shockproof in the tranny and change that once a year. I use their 20W-50 synthetic in the crankcase and change that every 5K (along with the filter, of course). As for the wet clutch and primary chain, I personally think synthetic is a bit too slippery for that application and prefer to use any good brand of 20W-50 dino there - Pennzoil has been cheap in 5 qt containers at Wally World - been using that since new (13K now). Cheapest place to find Red Line is almost any out of state mail order dealer - you save the tax and usually pay shipping - if you order case lots of their motor oil, it's usually a good deal. You'll not need that much tranny oil - order 2 qts at a time.

Switched out my tranny fluid to Shockproof Heavy and really couldn't tell any difference.

 

I don't know if this is true, but my local Harley dealer said if I run anything other than HD oils it voids my warranty. What has everyone else heard?

I'm gonna switch to Redline in all three holes.. Will I need to flush out the Syn 3, or after I drain itcan I just dump in the RL... If I will need to flush, whats the best method... thanks

 

Find a new stealership that is a bunch of chit.

 

Gee let them VOID your warranty for not using HD's oil... You could own that Dealership...
They Can Not Make you use there product or there service's.. That's a Legal NO NO in every State...

Oh yea... I use AMSOIL in the engine & Primary & Redline in the Tranny

 

Just drain your old oils and replace. This forum sponser is a good supplier and you get more discount.

 

Mobil 1 V-twin in the engine, Redline Heavy Shock in the trans, and Redline MTL in primary. Would have gone with Redline in the engine, but was able to pick up Mobil a little cheaper, and their both high quality synthetics. Bought mine at youroilshop.com since I can buy Mobil and Redline and the K&N filter all on one website -- plus their website is easier to use than myoilshop.com.

 

"I switched to Red-Line and my bike gained 30hp, my bald-spot filled in, and chicks dig me again"..some of these posts are funny when it comes to oil....HD,Red-Line, Amsoil, Mobil 1, Royal Purple,etc, etc....take your pick, they're all good..and for a Low-Tech machine like a Harley they're all adequate.
