I got a question to ask here and hopefully find a answer to this... I've got a 2008 Honda Rancher ATV I use here on the property for hauling stuff around.But my question is why is the Honda 420 Rancher have a oil change interval of 600 miles (or 100 hours)? What weird is my 83 Goldwing has a oil change interval of 6K miles. So why is the ATV thousand times less between oil changes?I'm considering moving to the 100 hours invertal even though the service manual specifies the miles first before hours. But I can blow through the 600 miles in no time in the summer being I get around 80-90 miles on a tank of fuel (3 gallons) I can suck up 2 tanks of a fuel in a day of riding through the forest looking for wood cutting spots.As for my oil its been dark brown colored but never black at 600 miles...

I have a 2 Honda atvs. I'm best guess is because of the environment there used for. I mean a goldwing is not going to ride in a river, a mud hole, or dusty off road trails. Sent from my iPhone

Is the clutch in the oil like my Suzuki?

Actually it did... All the road around here are dirt and the Goldwind went everywhere a normal pickup or car could go. That includes crossing shallow creeks, mud holes, dirt roads... Etc... Between the Goldwing and the Rancher the only difference is the filter size and the oil amount... Rancher is 3 quarts and the goldwing is 4 quarts. The Rancher filter is tiny compared to the Goldwing... But what horrible is the price of the Rancher filter is just about as high as a filter for the Cummins...

Just like the Goldwing and Rancher both have wet clutch systems...

Wet clutch, & most young people drive em pretty hard, is all I can think of. I run Rotella in all my quads too!

Well I'm not most young people... But I do ride it hard now and then. But still and all the Goldwing is a wet clutch too and ridden hard as well up dirt road with high temps and the whole bit and change oil every 6K...

I'm with you on this one. I have an 09 Rancher and feel the pain with the oil changes. If we can figure we can extend the interval I'd be pretty happy:thumb1: By the way how many miles do you have on yours Mike? Dave you say you run Rotella. Does it have the SJ rating (i think that's it) needed for the wet clutches on these ATV's? My neighbor tried cheaping on his quad oil but it came back to bite him because it wasn't spec'd right.

Closing in on 3K miles and 300 hours.I was also using 15w-40 Chevron Delo for quite awhile then switched over to 10w-30 now.

So maybe using that expensive Honda oil is a little wasteful on my part? I've got 825 hours and 4350 miles.

Are they both liquid cooled? If not that would be a good indicator if the goldwing is water cooled as I think it is and the rancher is air cooled the air cooled engines tend to get hotter and break down the oils faster.

Both the Goldwing and the Rancher both are water cooled... Both have wet clutches... But share the lube oil in the transmission... The difference is the Goldwing has bigger oil filter than the Rancher and holds 1 extra quart.What's truely sad is the tiny oil filter on the Rancher is the same price as my oil filter for the Cummins...
