I drain the engine and check the screen once a year. All changes in between I only do the tank. There is less than a cup in there and I change my oil often enough that it never really gets dirty. If your the type to run your oil for long time and let it get really bad then yes, I would drain it to get all the dirty oil and possible sludge out.So does everyone actually drain the base too. I hear some people do and some don't.
Thanks Ronnie and all the rest that replied. I do have a Wal Mart about ten miles away so I'll check it out and see if they have the number oil filter you described. This is my first Polaris so I need to learn the money saving tricks...Thanks allI use Mobile 1 0W40 and a Pure One filter. You can use either the 14612 or 14610 filter. The only difference is one is shorter than the other. I use the short one on both my XP and X2. You can buy everything at Wal Mart if you have one close by.
Pretty sure he meant "case", as in crank case. The 500 is a dry sump engine. That means it has an external oil tank and pumps oil out of the engine and into the external oil tank, faster than it pumps oil into the engine. This leaves just a few ounces of oil in the crank case. Some drain it during an oil change, some don't.What do you mean by draining the base etc?
