Coolhand lube is an unobtainable product commonly seen inside and around repair shops, mod shops, or garages in Grand Theft Auto V, like Los Santos Customs and Auto Exotic. Coolhand Lube appears as a sponsor on several racing liveries in Grand Theft Auto V and Grand Theft Auto Online.
It is likely a parody of Castrol and their Motor oil and engine lubricant products; this is evident with their similar colour schemes and stylistically similar font for "Coolhand".
- The name Coolhand Lube is a reference to the American 1967 movie Cool Hand Luke.
- The typeface used on the "Lube" text is Forte.
