does two stroke oil go off

As per title

Not in my experience, and I have some old 2-stroke kicking about that's 20+ years that I would use in an emergency. Manufacturers will undoubtedly say different. For the cost of a new bottle of Quicksilver or Yamlube that's TCW3 compliant, then buy new.

I asked same question last year


It's fine,, well been running on some very old stock (3-4years old )for over a year now ,and engines have not coughed,

I think this is more likely to be 10/12 years old! !

Probably fine as long as it has even consistency. Been selling the stuff for years and never had any go off...

Never read about unused oil going off

I was always taught that oil does not lose its viscosity. You can buy recycled oil who was the oil with the black contaminants removed. If you are worried, the stuff is cheap enough to buy new, compared to a new engine, however unlikely. It would be a different story if you have a drum of it.

Used to be a company just down the road from you Tecci that recycled old engine oil , they used to pick it up from my place of work then clean it with sulphuric acid re clean it , then we would buy it back from them ,some of our trucks ran 250000 + miles with no engine problems .
