Just bought some Castrol GTX 20W50 in order to make an oil change and stupid me didn't check the expiry date on the bottles so when I wanted to start the work I saw that the expiry date is April 2009. I am not going to make more than 2000 km until April next year (yeah I know...) so should I worry about the oil will become some kind of goo in my engine in the next six months or it will be ok?
