I know...a dumb question.....I also did a search really did not find an answer...
I have an 06 Ultra and I am going to change the oil on the bike. I bought it used and it has synthetic oil in its "holes"

I am going to change the oil for the first time.....What weight should be used?

I see 15 30 20 50......so I am not sure....

If read the manual....and I am still unsure...

I live on the East Coast.....NYC area......

Thanks again and sorry for the dumba$$ question

 

20w50

 

Mobil 1 15W-50 Full Synthetic from Wal-Marts. 5qt. container for $22

 

20W 50 whatever full synthetic you use make sure it is for V-twin engines.

 

in case you missed it, good reading for tranny and primary oil here: https://www.hdforums.com/forum/oil-a...ted-topics-30/

 

Thanks!!

I did miss it!

 

I run 20x50 in my bike as it's the recommended weight by Harley.

 

Thanks guys!!

I just ordered a case of

for $65 shipped not a bad price

 

+1....it's cheap at Walmart and approved for engine use in a Harley by Mobil 1. By putting this on their web page, they pretty much have to stand behind it in your bike.

Question:
Using Mobil 1 15W-50 in Harley-Davidsons
Several independent tests have shown that Mobil 15W-50 is virtually similar
to Mobil 1 V-Twin 20W-50 oil. Since Harleys utilize separate oil supplies
for the primary and tranny, is there any valid reason not to use the 15W-50
in a Harley?
-- Dave Gartner, Goodyear, AZ

Answer:
As long as the primary and tranny are separate sumps and there is no concern
for clutch performance, then Mobil 1 15W-50 can be used in a Harley.

 

Thats allful pricy in my opinion for mobil 1 syn: 6quarts for $65 thats over $10 bucks a quart. I can get Amsoil for less than that.
