Will a half opened cans of synthetic motor oil ';spoil';?

Not unless you have allowed it to remain open and gather up all sorts of dust and debris. Neither will natural oil decay fast enough to be of concern.Will a half opened cans of synthetic motor oil ';spoil';?
NO......!





How do you half open a can?





Grumpy says: ';Clem...half open a beer for me.';





Clem Says: ';Grumpy, you know I lost my half opener the other day at the pond, it went in the water with my fish straights.';

No.
Not if you seal it back up and store it away from heat.
why didnt you open it all the way?? motor oil will not go ';bad'; as long as you put the cap back on
If it's only 1/2 quart why take the chance of getting it contaminated by dirt.


put this in your car


1/2 quart is not enoug to hurt the engine because while your driving you will have almost 1/2 of your oil in the upper part of the engine
The only fluid in a car that will go bad if left open is brake fluid. Throw away a half open bottle of brake fluid after a few weeks. It is hydroscopic and thus will soak up the moisture in the air. The motor oil has no ability to soak up water, so no, your good.
NO! Oil that is not used will NEVER go bad!
