Hi
Not having much luck here with the search facility, so what I would like to know is, is the Harley Syn-3 oil which can replace all oils, i.e. engine, transmission, and primary, in other harleys, suitable for use in the V-rod motors where its all combined. Don't trust calling a dealer for this info to be honest.!!!
thanks in advance for any advice.

The dealers will recommend changing to Syn-3 at the first oil change and they'll also try to sell you chrome oil filters when the black ones work just as well, cost about $4 less, and look just as good in the trash when you throw them away.

Many folk will tell you that Syn-3 ain't all The MOCO and dealers tout it to be. I am one of them.

I put Syn-3 Oil in my 09 Muscle and haven't regretted it since. I feel better putting Harley recommended products into my bike, granted you pay out the nose for it, but it gives me some peace of mind.

I use royal purple 20-50...I use to use mobile 1, but then I saw a demo for the purple stuff compared to mobile 1 in person and I was super impressed....I put royal purple in every thing I own now. Until i see how well amsoil works in the same type of test, I will stick to the purple stuff.

the syn3 oil is ok, theres been plenty that use it with great success but personally i like amsoil. theres a couple dealers for amsoil on here and you can get it shipped to your door for about the same price the dealer will sell you syn3.

SYN-3 is not 100% synthetic. My bike use to drink it like water. I use Amsoil now, and no more problems.

i used Syn3 and it used oil loads ! there were loads of posts on this forum saying that because syn3 was not a true syn oil the weights will seperate and the lighter will burn off , hence using oil !

i have Amsoil in mine now and it has stopped using oil ! so there must be some truth to this.

i would not use syn3 , but Motul or Putoline as over here its Ester based and from good base stock and its prob half the price of syn3

My bike shifted better after switching from SYN-3 to AMSOIL.
Add one more to the list of Amsoil believers.

Mine did the same...I changed to Syn3 on the first oil change and it drank oil all the way up to when I changed to AMSOIL @5K mark. The rings seated great after that and no more added oil between oil changes....

Well thanks for all the replies guys, will have to decide what to use soon.
I have no-problem in getting Amsoil, I have a stockist around only 3-miles from my door, its more expensive than the Syn-3, but it looks like the majority goes with the Amsoil.

Amsoil states that you can double the mileage between oil changes.

I didn't like syn-3 either, switched to Mobil 1. Much better. Amsoil next, filters and oil.

After I broke my bike in I used the syn 3, I absolutely think it's CRAP! My bike drank it like water. I brought my bike to the dealer and they wanted to do a teardown (under warranty), but after so many bad experiences with the one local dealer (red rock harley) I decided to try amsoil, after two oil changes my bike does not drink oil anymore. I wrote to Harley back a couple of months ago and still haven't had any response. I quess Harley knows it's crap too.

Baby Oil is best, squeezed from big fat babies.
