Fatboy fluids question
I do use Full Syn but the Auto kind...The V-twin is ok if you're gonna use it in all 3 holes but i don't so a Automtive 15w50 or 20w50 is fine...
Most mFG's put V-twin on a bottle and charge 3-4 dollars more...
I found my bike shifts ok with HD Formula + and it's easy to get.
LIke i said also...oil is a very personal choice...
The statement at the end of the study:
"The cost difference between the average price for motorcycle oils and the most expensive oils is less than $15 per oil change. If the performance of an oil can support an extended oil change interval, that cost is reduced.
The consumer must consider the performance and benefits offered by an oil and how those benefits affect their motorcycle investment to determine the oils value.
This is why I offered the study for those seeking information to assist in making a decision.
I will probably upgrade to a better 20W50 oil next change. just not sure I'll do a $14.00 a quart synthetic although it is cool that aparently there is no problems going from dino to synth in a harley. having it run cooler in the HOT Florida summer does appeal to me.
thanks again for all the input.
Notgrownup, I change my engine oil every 3000 miles and I do primary and tranny every other oil change.

Oil is oil guys. Yes there are products with better basestocks and stronger additive packages but if you are changing any oil at 3000 miles then you aren't even close to depleting the add pack or running out the TBN.
The royal purple comment is funny. Using it showed the poster that he has a gasket problem that he chose to ignore. Even if it isn't leaking with a different oil the gasket is obviously compromised.
Every virgin oil analysis I have seen in different weights of royal purple has shown it's additive packages to be very stout indeed. The racing varieties have an assload of moly and zddp,but low sodium(cleaning agent). The API verified versions are actually scaled down versions with more cleaning agents.
These oil threads are entertaining. I use amsoil,mobil 1 on occasion,would love to have a stockpile of red line but it's hard to come by locally.
Any modern oil will protect an engine to the 3000 mile minimum. Kool aid or no Kool aid. High end oil doesn't insure long engine life any more than eating healthy insures a long human life.
I think I have convinced myself to use redline shockproof heavy in the tranny.
Belwo is an email from Jim Morrisey with Royal Purple, I was going to follow his recomendation for Primary fluid. I understand clutches need friction..so I may back off this to just regular HD primary fluid and put the UV dye in there.
I am going to use a better oil in the engine but I cant afford $15 a quart.
I see the oil topic is like discussing caliber on a gun forum.
Thanks for everyones help... this is a great resource...
