can you just change oils if you've been using one type for a while now. i've been running some Maxima trans oil and some GTX for motor oil. i want to Swtich over to all Pro Honda stuff. I know you cant just change food on your dog or it will throw up, just checking about my four wheeler too! lol.

also, does anyone know if the CRF250 oil filter is the same as the 450? i have an extra CRF250 oil filter and it looks identical to my 450R oil filter, but didnt want to take the chance unless i know its ok.

thanks
