TFT 0 Report post Posted July 24, 2011 Im thinking of getting circa 20L of 10w 60 Castrol Edge Racing for a very good price. What sort of shelf life would it have once opened? Prob do me for 2 years I reckon. Inc oil changes and tops ups. T Quote Share this post Link to post Share on other sites

Smaky 73 Report post Posted July 28, 2011 10 years and shake before use, after that it requires a retest and will probably beextended for 5 more years. Quote Share this post Link to post Share on other sites
