Not interested in a 'who makes the best, this one vs that one thread', Iwas Just wondering, what are Your intervals between changing the oil, tranny & primary?

Thanks,
Dave...

 

Engine = 5000
Primary = 10000
Tranny = 10000

Per HD manual:

All Three Holes: 1k, 5k, 10k, 15k, 20k

Engine Only: 2.5k, 7.5k, 12.5k, 17.5k

 

I don't know about your manual, but mine says the following:

Engine: 1k and every 5k
Primary: 1k and every 10k
Tranny: 1k and every 20k

I change the Primary and Tranny together at 10k however. I just can't bring myself to leave my tranny alone for 20k miles.

 

Engine = 3k
Primary = 10k
Tranny = 10k

 

I change all three every 5k.
My Brother changes all three every 3-3.5k
This is using synthetics.

At least for the 10k plan on also doin the tranny just cause.....adding heavier gear lube

 

all depends on mileage... 5-7000 miles or about every 6 months, whichever comes first...

 

I change them all at 5K with Syn3. The manual does say you can go 10 @ 20 on the other holes but it's just as easy and not alot more $$$ to do them all at one time !!! IMO

 

Every hole @ 5k w/ Amsoil.
