So I'm in a dilemma. I just changed my oil a little over 300 miles ago and when I did I just used some non-synthetic HD 20W-50 stuff. Well I've came across some AMSOIL 20W-50 and I want to throw it in. Me being a cheap a$$ I was wondering what would be the harm in just changing the oil and not changing the filter? I mean it is barely even used?

I know what's $15 bucks or so for a filter, I was just curious on everyone's opinion...

 

Why dont you just wait till its time for the next oil change? Other wise I would change the filter to. So you dont mix the two oils.

 

My vote change filter. Just my .02.

 

Goodness.

 

No harm at all just changing the oil - if fact I read awhile back that a filter was good for 10,000 miles and that you could skip a filter change at 5000 miles without damage.
But, a highly rated filter is a WalMart SuperTECH # ST4967 for a couple of bucks. It fits most Harleys.

 

x2. I did that a couple times and never had a problem.

 

No harm in taking the filter off and draining out for 30 minutes and reinstalling it and dumping in the Amsoil! IMHO!

 

Why waste the oil with only 300 miles on it?

 

Just change the oil filter.

Think about it. You are worried about waiting until next oil change because of non-synthetic oil being in there but are now questioning if you should change out the filter?

 

Usually one thinks all oils are the same, but the fact is their not. I wouldn't worry about reusing a filter if you replaced the first one that came with the bike. Break residue should be taken out. In your specific case I wold change only because you had different oil and just would take a risk of the two oils reacting in any way that could affect the engine as charle suggests.
