We cooled Castrol EDGE Sport 0W-40 to a range of extreme cold temperatures and then compared its flow to a competitor’s 0W-40 fully synthetic oil. At -55C Castrol EDG Sport 0W-40 still flowed while the competitor’s oil had almost solidified.

With its top quality base fluids and great cold fighting polymer technology, Castrol EDGE Sport 0W-40 is our best at shrugging off the effects of cold, flowing faster in extreme cold conditions.

Proven to outlast competitor synthetic oils in extreme cold conditions.
