I've got a 98 Honda Fourtrax 300 and need to know what type of oil I need in order to change it. Will regular vehicle 10w-40 work or is that a bad idea? Thanks in advance.

Just whatever ATV oil you can find, use oil designed for your intended purpose IMO. Must be JASO MA rated as Retro said. I use Amsoil Formula Fourstroke 0w40 typically but have also used Lucas oil in the same viscosity. I only run Synthetic but on an older machine you may be just as well off with conventional. A lot of guys run Rotella 15w40, I don't know where you are at but if I had that in my engine in January it wouldn't be pretty lol

With the Rotella's, be carefule which exact one you get. T6 5w40 full synthetic that a lot of guys run is JASO-MA. So is the T4 15w40 mentioned above. But T5 (also available in 15w40) is NOT. The T6 is better in cold climates than the T4.

Ok so just to make sure. I need some type of 4 stroke motor oil for wet clutches? Or should I just get a JASO MA oil? Thanks again.

And also what type of oil do I use for my front and rear diffs? (First 300 just trying to make sure it lasts)

To qualify as a JASO/MA oil it has to meet the requirements of at least one from a list of basic 4 stroke oil standards. If it says JASO/MA OR JASO/MA2 on the bottle, you're good to go.
For the gear oil, something that says it's for Hypoid gear oil, or says it meets either API GL-4 or GL-5 is what the newer machines require. I'd expect your 300 to be the same but someone with one can pipe in.
Gear oil weights depend on whether you have cold winter temp swings in the area you ride it or not. I gotta tolerate -40 F temps in the winter along with 95+ F temps in the summer, so I use 75w90 full synthetic gear oil in car & ATV diffs and sled chain cases year round. If refilling a limited slip diff, make sure the gear oil you buy is intended for use with the friction disc material in the clutches. Some of the old-school automotive limited slip gear oils can chew up paper or cork frictions over time. The brand you buy is your choice....

If you're still doubting it, post pictures of front and back oil bottle label and we can tell you exactly if you can use it or not.

Yes that is exactly what I used just wanted to triple check. Thanks to everybody on these forums y'all are extremely helpful.
This is what I'm currently running in my 2014 4x4 Rancher with the DCT. It seems to work fine.
