2008 Outlander 650xt.

I’ve read 100 threads across this forum and others. Can someone please explain to me what size oil drain bolt I need and where I can get it?

I stripped the stock one. I would rather not pay my dealership $150 to fix it and I’m not comfortable going the helicoil or timesert route myself.

I’ve read good things about just "buy a size up, grease it, and put a good washer on it"….

I went to AutoZone and had no clue what the hell I was looking at. M12x1.25 or M14x1.75, etc…. I don’t know what size I need, what type of bolt I need, or where to get any of it.

Any advice is welcomed. Thanks!
