The tune from Mahler's Seventh Symphony was remixed by composer and A-level music teacher Mark Taylor for Castrol's competition to create a ringtone.
The original aim of the competition was to introduce younger people to the brand. But record producer Adam Perry was so impressed by Taylor's song that he asked if he could produce a single from it.
The single, It's Liquid Engineering, will be available to download from iTunes, 7 Digital and all digital retailers from 25 August 2008.
