I switched to Mobil 1 but in the real world I doubt there's any difference from Syn 3 under normal use. If they were out of Mobil 1 I'd have no problem using Syn 3.

I think a lot of the bias against Syn3 is because it's from Citgo. ie: Ceasar Chaves, not because of the quality of the oil itself.
Not saying that that's a bad thing, mind you! :D |
A topic of debate for sure! I've also heard Syn 3 was only 60% Syn, so it's called Syn. I'm dumping it next change for Mobil 1 V Twin!

Damn! I didn't know citgo made the syn 3. I will change to Amsoil immediately.

If you clicked the link in the 3rd post you'd see that it is not a blend. It is a full synthetic motor oil.
That is not published by the MoCo, but by Rocky Mountain HD. Just because someone finds info on the WWW, doesn't make it fact. I'm not trying to create a fight here, but I will try to find more factual related info on this and post results. Has anyone noticed, HD doesn't divulge much if any info to the consumer? Look at your HD oil bottle, they do not have/show API ratings. If you ask a dealer a technical question, they or the service department can't really answer, as they don't know themselves. HD is a Top Secret Company that holds their cards close to the vest, LOL. They want you to believe only their product will work in their product, so they can tap into your wallet. |
Here's an Amsoil Test. Yeah, I know!
Like I said, it's difficult at best finding factual anything, about HD! http://www.harley-performance.com/ha...idson-oil.html http://www.cycleforums.com/forums/sh.../t-113159.html |

I know this has been asked 10,000 times. I don't feel like searching all day for an answer. Is SYN3 a full synthetic or a mix? I asked 2 people at my local dealer and one said it was full and the other said it was a semi??? Thanks.
To answer the OP's question, according to the "Material Safety Data Sheet" for H-D's SYN3 it is chemically a blend of 60% synthetic and 40% petroleum oils. But, the chemical composition notwithstanding, the courts have ruled that it is legal for them to advertise their "60/40 blend" as a "synthetic" motor oil. Material Safety Data Sheet (MSDS) on the SYN-3, as filed with the Federal Government. Manufactured by Citgo Petroleum. Composition section: Component CAS # Concentration (1) 1-Decene Homopolymer, hydrogenated 68037-01-4 50% - 70% (2) Proprietary Ingredients Proprietary Mixture 1% - 10% (3) Polyisobutylene 9003-27-4 1% - 10% (4) Distillates, Petroleum, Hydrotreated Heavy Paraffinic 64742-54-7 0% - 20% (5) Distillates, Petroleum, Solvent-Refined Heavy Paraffinic 64741-88-4 0% - 20% (6) Zinc Alkyldithiophosphate 68649-42-3 0% - 2% Item (1) is a Group IV base oil. unable to locate the manufacturer of this base oil. Group IV and V base oils are the only "true" synthetics to the cognoscenti. Item (2) is probably their additive package (boron, calcium, magnesium, phosphorous, moly), but it is conceivable there could also be some "secret" synthetic oil, maybe an ester type oil, included in it. Item (3) is a fancy name for synthetic rubber (or elastomer) but this is probably considered to be "synthetic" oil as well. However, Item (4) is a Group II base oil, namely Conoco Pure Performance Base Oil, either 110N, 225N or 600N. no one is calling a Group II oil a synthetic. No information on the group number of Item (5) but it is Conoco's Cit-Con 650N Base Oil. It's presumed that it is a Group I oil as it is solvent refined. Most quality blenders are not using Group I oils in their premium motor oils and they are not considered synthetics. (From the MSDS for the HD 360 20w50 oil: The major base oil constituents in it are the same ones as are listed in Items (4) & (5) above.) I think the Items (4) & (5) above, are to keep the old air-heads running without bearing skid and gasket leaks. Good for them, but not for us? Harley-Davidson talks about SYN3 in their advertising as: "Developed with a proprietary blend of three synthetic basestocks, ..." Or not!?! Since there are significant amounts of Group I and II oils in the SYN3, could the MoCo have stretched the definition of "synthetic" a bit further than Castrol did when changing Syntec from a PAO Group IV base to a hydrocracked Group III base? Exxon/Mobil (Mobil 1 synthetic) lost a lawsuit trying to go after a few oil companies for advertising blends as full synthetic. Mobil lost, and now the oil companies do not have to disclose on the label it contains Group I, II or III base stocks which are all petroleum based. So it is legal for Harley to market syn3 as a full synthetic, even though it is only 60% synthetic and the rest petroleum based. If you want fully synthetic. Buy Mobil 1, RedLine or Amsoil, although Amsoil always seemed a little too "snake oil" for me. |
