 Shocked I'm new to the valkyrie world, I've got a 1999 interstate and the book requires 10 W 40 motor oil but I don't want to use synthetic because of the wet clutch. Does anybody use any other viscosity other than 10w 40 or synthetic? If so why can't I find Shell Rotella 10w 40 conventional? Please help!

I use Synthetic no problem. Many use shell Rotella T6 for diesel.

Honda sells both a synthetic and non-synthetic oil both of which they
recommend for our bikes. There's a whole bunch of other readily
available oils that are also acceptable. I run the Honda GN4 only
out of a habit formed back when the HDL web page had a Valkyrie-specific
page where I'd click on "send me a case of oil and a pack of oil filters"...



Our motors are so good, you'd probably get 300,000 miles on this oil:

I have over 250,000 miles on 3 Valkyries and a Gold Wing in 22 years always using Mobil1 full synthetic.  No clutch problems at all with any of them and in fact the bikes really seem to like it with smooth shifting and quieter tranny.  YMWV - but you have made up your mind that synthetic is bad for wet clutches so whatever...

Never read where Honda said that. They sell synthetic oil. I myself have started using the mobil 1 also.

It's not synthetic oil per se, but the 'energy conserving' types that slick up the clutch plates. As long as the oil has a JASO MA rating, it is fine, synthetic or cracked.

not all oils that can be used will have a jaso rating.

see article  Two-wheelers love oil too!

JASO spec'd motorcycle oils are basically the same specs as heavy-duty diesel oil standards.
JASO does not test oils, manufactures pay a fee to JASO and state their oil meets the specs.

True, because not all oils have applied for it. An example was Rotella T6, which was used for many years before they had it tested by JASO.
But, all oils with a JASO rating are known to be safe to use.

Hi Kzapped.

Look on the back of the oil container.

You'll see a logo like this

https://www.carsomesg.com/assets/kcfinder/upload/carsomesg/images/Engine-oil-rating-watermark.jpg

DO NOT USE oil that has /"energy conserving" in the bottom half of the logo.

Any 10/40 regular or synthetic without it is good.

actually the oil recommendations have been the same since the first '88 Goldwing engine

10w30 up to 90F

10w40, 20w40, 20w50 above 90F

this was based on 1988 Dino oil technology. today's dino and synthetic oils are a 100 times better than '88 oil.

I prefer 10w30 or 15w40 diesel oil.  if at 40F and above a straight 30w would give the best protection. The early Goldwing 1500 manual actually listed straight weight oils.
