* The calculation factor of 3.8 given for used oil is made up of 1.22 kg CO₂ for the fresh oil and its production and transportation + 2.58 kg CO₂ for the disposal and recycling of the used oil and assumes an extension of the oil change interval by 100 %.
The actual CO₂ savings potential is likely to be much higher than the above factors suggest. Longer oil change intervals (backed up by trend analyses) make a significant contribution to reducing your company's CO₂ footprint!
