so I got the "check eng oil lvl" light. No big deal I get it a lot when I get close to having to change my oil. I usually just have an extra qt. In the truck but this time I don't. I went into the garage and found some 10w30 my dad uses. I've topped it off with this before. But it's 5 years old. I've looked it up and everywhere it says it's good up to 5 years. What should I do. Ok to use it till i change my oil in 1k miles. It's a big 5qt. Bottle and it was still sealed and unopened
