Here's my two cents (with inflation im not sure) i have been a harley mechanic for over 35 years... We used Halrey oil on all the bikes(I had a shop)and never saw the oil cause a problem.. We have seen a lack of it or deciding not to change it cause problems but never a problem with the oil itself... I am not going to put down outhers ideas about oils but after this many years and the thousands of bikes i still use the Harley oil!

 

For my first 40k I used harley 20/50, 40k-100k I used mobile1 15/50, changing every 5k. Oil filter change every 5k. At 100k had engine rebuild due to defect in case that was non-oil related.

From 100k-150k I have been back to harley oil 20/50, but now changed every 2.5k.

I have not seen any significant difference between the 2 oils nor between the interval of the change. I will continue with harley 20/50 every 2.5k. I think using any decent oil that meets specs and is changed regularly will do the job but the specific brand or synth/dino won't make any significantdifference if you are changing every 2.5 k. If you are stretching it out to 5k or more then an oil that does not break down as significantly will be more important. Rather than thinking about which oils will last the 5k or so, I just change at 2.5 k and don't worry about oil breakdown.

 

Do we know this for a fact?? That is one thing that would make me look into options.. But, its got to be more than just hearsay..

 

I run HD dino and HD filter, HD primary mostly because I get $25 chrome cash from a credit card, so the oil is dirt cheap. I recently changed to running Redline shockproof heavy in the trans, and I really like it and I can get it local at Jeg's.
edit
One thing though, if you get one of those credit cards, don't put more on it than you can pay off each month, the interest rate is like 14 to 20% depending on your credit. It'll put you in the poor house quick if you are irresponsible. my 2 cents

Well, that sux... Where did you find that info? I'd pay $5 more per qt to avoid contributing to that dirtbag..

 

Just my .02 ... I hate that dog Chavez also. But the amount of oil that is used by the US doesn't even affect his bottom line. You have seen all of the emails boycott this boycott that. Citgo was unaffected by this boycott. I'm unsure of how many actually boycotted but still it hasn't hurt him. snopes.com has stories relating to boycotting citgo btw. As for oil I ran valvoline vtwin 20/50 after the first couple of change and then cjanged to H-D brand due to having to get filter there just get oil too. I have run it 40k now and the bike still runs smooth. the 5 bucks additional for the 3 quarts combined is not worth the hassle to me of running to another store for oil. Heck gas money is 3.50 gallon now so 25 extra miles getting oil in my camaro and i save a dollar. I have tried Mobil 1 also 15/50 and it did nothing but made my rocker gaskets leak.Again just my .02 Kent

 

I told you,The lowest bidder. HD oil is another way of HD getting into your pocket.

I am still smiling on the one thread that stated "

The factor to keep in mind is that HD(regardless of who actually makes it)oil is designed as a coolant, not just a lubricant, for an air cooled engine.. "

I guess that the air that runs past my fins does nothing and the oil cools it all.

 

I run Havoline 20w-50. It's a great oil based on all the UOA I've seen.

 

Well, at least we're amusing eachother.. Thats a pretty ignorant statement..
