Oil shelf life?
Just wondering if a bottle of dino oil is unopened, what is its shelf life? Will it last 1 year? 2 maybe? Reason I ask is I have a bottle of Castrol GTX in the trunk as a back up. It's been in there for about >1 yr now. Should I use it and replace with a new one?
One more thing... Penzoil or Castol GTX? |
It will last forever.
Castrol GTX. |
2-5 years from some quick research
Engine Oil Bible - search Shelf Life. Wiki Answers Better use up that quart in your trunk and replace it with a fresh quart :) . |
it would last a LONG while
but if its already a year old, might as well just use it and replace it fresh one. I dont see why not. |
I hope that u have added oil in the past year and the one inthe trunk is just an extra extra....i say use that extra one now and put a fresh bottle back there.....
oh I use Castrol 10w30 engine oil and Pennzoil Marine synthetic Premix |
