I changed out the oil a little early on my Goldwing.
92,930 miles on the bike, 3,480 miles/6 months on oil.
Out: Peak 15w-40 syn-blend and a NAPA Platinum 41356
In: Supertech 15w40 and a Fram PH7317 (with orange ADV)
I already posted the reason for it in
another post, but will post it here as well since I actually changed the oil this afternoon.
The Goldwing is a 5,000 mile interval service (just easier to remember to do it every 5,000 miles on the odometer)
I discovered last month I had a leaking clutch slave cylinder.
Because of how it is set up, there is a small possibility that some of the brake fluid may have leaked into the oil.
I really don't think it did, but I don't want to chance it.
I went with Supertech and a Fram because of this, ~$15 for piece of mind.
It will be a short 2,000 mile run as well, just to get me to 95,000 miles.
A that time, hopefully Mobil 1 has a rebate again.
If so, I will be getting some Mobil 1 10w-40 HM and use another NAPA Platinum from my stash.
I can then go back to the 5,000 mile interval on the 5's.
Here is what the slave looked like if you are interested:

Inside where slave mounts, where rod goes into engine:
I also ended up having to rebuild the clutch master cylinder as well. Found it had been leaking a little as well, so took care of that at the same time.
Now has fresh seals and fresh DOT 4 fluid, so good for another 2 years.
Brakes are due for flush as well (was done about 2 years ago), and will be doing those in the next few weeks.
