So I’ve recently bought a 2000 ford ranger 3.0 6v. The spark plugs go bad like twice a month. Just trying to figure out what is making the spark plugs go bad.

 

I'm not on the "Welcoming Committee" but seeing this is your first post, welcome! Someone with actual juice will be along at some point to welcome you for real.

Give more detail whenever you post.
In your case:
1) Your NTY Ranger's trim level, mileage, modifications or damage
2) Type and pn of any plugs you've removed
3) Description (or pictures) of the plugs' likely failure point (no remaining electrode, oil fouling etc.)
Since you're R&Ring your plugs, I'd take the opportunity to perform a compression check even though these engine's are hearty.

Did you get any service records with your Ranger? Best of luck with it.

 

You have to use double platinum plugs.
Your description of plugs "going bad" isn't very specific, but if you're using copper plugs they won't last long.

 

Welcome to the forum

Yes, +1 ^^^, please post the model number of the spark plugs you are using in the 2000 3.0l V6 Ranger
Ford specifies AGSF-22FM and GAP should be 0.044, NOT 0.05x <<< as may be shown on trucks emissions label, misprints on many
