changing the oil this weekend, i normally use hondas hp4 4stroke oil but was wondering if there is a cheaper oil you can buy from walmart or autozone or something that works just as good

I just changed the oil in all four of our atvs.....and used Shell Rotella T synthetic 5w-40. Only thing I hate about it is that I have to go to Walmart to get it. That is all I have ever used in our atvs.
I also use the same oil in my Yamaha V Star.

Shell Rotella synthetic also carries the JASO-MA rating for motorcycles.

Our atvs...an 04 Yamaha Bruin 350 4x4(wife's) 06 TRX 90(grand kids), 07 Honda Rubicon(mine) and a 09 Recon...my son's.

i use yamalube for my 300ex

Yamalube and GN4 are pretty much the same, just different labels....

Be careful that you get oil that is designed for wet clutches. You can cause some serious issues if you don't...
