Motor head question.

This 1 is for all you motor heads out there. I have a gallon jug of 2 cycle oil that I bought 4 years ago. The foil seal is still on the oil. Should I use that oil or chunk it? One of my buddies suggested using it at a 2 to 1 ratio with new oil.
 
As long as the oils says TCW 3 on it it is fine! I always use 50:1 no matter what.

I got some oil from a garage and it had been there for years!!! It was Exxon but it had TCW 3 so i used it, No problem's
 
Thats what I figured but I had to ask. I was raised to believe that there is only 1 dumb question and that is the one that you don't ask. Thanks MJ
 
Pre-mixing you'll be fine, I've used 2 stroke oil that was 10 years old before without problem. Oil injected is a whole nother demon entirely though.
 
this came up in a Mercury class I was in several years ago, hey said the biggest problem is if the oil got below freezing, supposably the oil will gel if it gets too cold, and it won't return to its normal condition even after it warms up, seems there were a rash of power head failures after an early cold snap, all the pickups were stopped up with oil gel
 
So Spare, your saying that the oil left in my reserve over the winter is no good :-/ ??? ( My engine is oil enjected)
I have had the boat out a hand full of times with out any major problems ( 1 rock, but thats a diffrent story :P :-[ ) but I do top of the oil each trip. should I drain the tank/reserve?
 
not an easy answer, but the official view from the outboard manufactures is to drain the oil resevoir and clean the pickup screen each spring, I don't know anyone that does that, although its not a bad idea. It doesn't even get close to freezing around here,( i guess I just jinxed us for this winter) so I haven't seen the results personally. They were just warning us that the oil wil congeel and turn to gel if it gets below freezing. Try an experiment, put some in a jar and throw it in the freezer, see what happens, got me curious myself
 
Thanks! A science project for my daughters  ;D
I can hear it now, (the wife) Hunny, the choclate/caramal syrup in the freezer doesn't taste right :D
 
I no longer have injection, but when I did my oil tank was full and in the boat all winter and never a problem
And I can assure you It gets cold here!
 
When I was running the Renkin I would go fishing when it was below 32 degrees and never had a problem with the oiler. My main concern was the additives in the oil and if age would affect them.
 
snowmobiles are oil injected and it's way below freezing 95% of the time you ride them! never herd of the newer injection oil gelling up because of a freeze thaw cycle.
 
My marine ( Yammie) wrench sez the oil injector systems are good for stretching the use of oil according to load but, ditching it and mixing the oil yourself @ 50:1 was always better.
