I've read some threads that recommend changing the outlaw 525 oil every 3 hrs? unfortunately when I purchased my atv it didn't come with a manual. ive also read that depending on the oil you use makes a difference on how often to change. its an 08 so im well passed the initial first couple of oil changes and can change my filter every other oil change..? please give me some feed back. also how can I tell its time for an oil change? does your motor over heat and wont start for a while possibly draining your battery? my window level is good but I have about 61/2hrs on my last oil change. im running rottella t6. doesn't look to dirty either.
