Fluids & Changing Intervals
Alright, I've been hearing mix comments on when you should change your engine, transmission, and primary chaincase fluids. I have an '08 Road King Classic. So, I want to see what you guys on here are doing...
All three use the same type of oil, correct?
I'm using Amsoil 20W50 Synthetic.
How many miles do you put on your:
1) engine oil?
2) transmission oil?
3) primary chaincase oil?
Thanks...

What made the service interval on my '03, every 3,000 miles to the 5,000 mile interval on the current bikes possible?

Thanks guys... I'll probably continue changing my engine & primary oils every 5,000 miles, or every Spring, and my transmission oil every 10,000 miles. I'll look into a heavier oil for the transmission...
Not sure if I'll continue spending the money on Amsoil... Might switch to HD SE synthetic.

I don't ever remember a 3,000 mile service interval on fluid changes on '03. Where'd you hear that? It's always been at the 5's until 2006 when HD extended the interval on the trannys to something like 20,000.
HD doesn't even have a 3,000 SERVICE interval. ( Has always been 1000, 2,500, 5,000, 7,500 etc.)
