Is there any aftermarket drain plugs that don't have a square hole? Mine is getting wallered out and I am afraid of stripping it soon.

 

Femco is a no spill system that works great. Initial cost kinda sucks ($70ish), but life is real good afterwards.

Engine Oil and Fluid Drain Plugs & Valves - No-Spill™ Systems

I have on on my truck, and every piece of equipment in my fleet. They are awesome.

10-22150-10 Standard LB - No-Spill™ Systems

That should be the right one. The part numbers and prices are listed. Most semi truck dealerships have them, as well as heavy duty parts stores.

 

That's bad@ss I've never seen those before. I just bought a standard drain plug last time.

 

Weld a big nut on it next time you change oil.

 

I put one of these on my truck with a big ole clip so it can't open itself or what not. works pretty good

Dodge 5.9L Cummins Fumoto Oil Drain Valve 94-02 Diesels

 

I just bought a new stock one, figure it's good for another 15 years

 

To me the design of the Fumoto won't allow all the old oil out of the pan. However, I could be wrong but seems like the threads go into deep.

 

I thought the same but after the first oil change with it i pulled the valve out and all that came out was slow dripping just like a plug so i'm good with that.
