This is not related to any car but concerns a John Deere 318 lawn tractor that is around 30 years old. It has developed a oil leak from a front seal. Does anyone recommend the use of stop leak, the pros and cons? I personally am not a big fan of a quick fix remedy. I would sooner repair it the correct way.

 

I wouldn't bother with snake oil. Does your tractor have a diesel engine in it? If so, it might have an oil cooler that could be clogged. None of the snake oils are well rated anyways.

 

Gas powered, no oil cooler

 

Check you don't have a blocked breather and change the seal, Surely the best way to fix it long term. Snake oil remedies normally make the seals swell, temporarily helping cure leaks, but not a proper fix.
