Car has been sitting for about 2 years, will I need to change this particular oil or will it be ok to drive 100 or so miles on it?

Take out for a drive, and drive it hard, then change the oil with new filter. It only 29 dollar oil change, autozone have good deal andoil fiter on gc now.

I already have the oil and filter before the autozone deal, so it cost a bit more than 29 dollars. I'm just driving the car back to Orlando from Coral Springs and if the oil that's in there now can survive then that's good news.

What happens over time that makes low mileage, especially a synthetic, oil to go bad?

I drive my cars less than 500 miles a year. It seems like such a waste to dump the stuff when it is still clean and clear.

Coral Springs to Orlando is a hell of lot more than 100 miles.....closer to 180-190 for you. It was 221 miles door-to-door for me, I live in Lauderdale. My house was right off I-4 and the Turnpike.

But even it was 5 miles down the street....you'll be killing your internals.

That oil is no longer oil................its completely useless. You drive it with 2 yr old oil and you WILL damage your bearings.....oil is only good to sit for maybe 4-5 months after it has been run in an engine. Its not only mileage...its time limited after it has been run in an engine.

I'm not trying to be a smart *** but after 4 - 5 months and the oil is no longer oil? If that is true, I've ruined the engines in all 5 cars. Where does this information come from - can you lead us to something else that will substantiate this?

Re-read...........

That 2 yr old oil is completely broken down.....thats what I said was no longer oil. And don't be a cheeseball...I don't mean its Cool-Aid or Ginger Ale now.......I mean its completely useless after 2 years and WILL NOT protect like its supposed to do.

I said after 4-5 months of oil JUST SITTING makes it a bad batch....IF it has been run in an engine. If it has not been run and it was just sitting there in the pan, then maybe its ok after 4-5 months of just sitting. But there's probably gonna be moisture build up in there, so it can still damage your engine if you run it after 4-5 months of just siotting and not running to burn off the moisture that builds up.

Its AFTER oil has been run in an internal combustion engine......that it immediately starts the breakdown process. 2 yrs...thats just ridiculous.......

Roarin_8 and anyone else for that matter; I thought this to be an interesting read regarding oil life.

http://en.wikipedia.org/wiki/Motor_oil

And here's the most comprehensive article about motor oil that I have ever come across. It is long and covers everything imaginable; explaining the grades, viscosity, additive packages, sources and chemistry. Very well written and even a little entertaining.
