Maintenance

This range covers the vehicle maintenance products that sit alongside a normal service: AdBlue diesel exhaust fluid, engine flush and related workshop chemicals.

AdBlue is a high-purity urea solution injected into the exhaust of modern diesel vehicles fitted with selective catalytic reduction, where it converts nitrogen oxides into nitrogen and water vapour. Purity matters more than most people expect, because contamination or the wrong fluid will damage the SCR catalyst and trigger derate warnings. Keep it in sealed containers, use dedicated funnels and store out of direct sunlight.

Engine flush is used before an oil change to loosen sludge and deposits so that they drain out with the old oil rather than staying behind. Follow the stated idle time, never drive on flush, and always fit a new oil filter afterwards. Available in 500ml through to 210L packs.
