Tcw-3 oil
 

Does tcw-3 oil go bad? Expire? If in a seal gallon container?

The recommended shelf life is 36 months as long as the oil is in th original sealed container.

That sucks, then I guess I will be selling about 12 gallons at my next yard sale

I m running some Merc Premium in my 2 stroke lawn equipment that s at least 8 years old, no issues. I do premix, no injection system. I ran 30 wt Quaker state in my first OB, small coke bottle in a 6 gallon metal gas can.

Quick google search says 5-8 years

I would be hesitant to use in an Optimax or modern Evinrude, but not in anything carbed and premixed

Phat,straight 30 wt oil? Isn't that a no no?
My engine I add it in the gas and just bought like 20 gallons. Pennzoil marine and Quick Silver Tcw-3. On clearance. It was so cheap I had to buy all of them from 3 differant locations.
Do you live in nj?

Step, remember that the 36 mos is the "recommended" time, not the actual usable time. As far as I know, it's oil and should be good for lots of years. Hell, it's been in the ground for a million or so. I still have 2 gals of Quicksilver that is at least 6 years old and I run it in my 1993 200 Merc carbed with zero problems.

Destroyer,if there are any advance auto stores by you or you can get to one they put pennzoil and quick silver on clearance. Fantastic price,believe me
Don't go to the one in Dover or rockaway nj I already bought all of them. Check it out.

Good to know. Thanks Step. I'll check them out later today :clap:
