Diesel Waxing (Fuel Gelling)
Diesel waxing is when paraffin in diesel fuel forms wax crystals in cold weather and blocks the fuel filter.
What is Diesel Waxing (Fuel Gelling)?
Winter diesel is blended to resist waxing at lower temperatures. The cold filter plugging point shows the lowest usable temperature. Symptoms are power loss, stalling or failure to start. Fuel stations in cold regions sell winter grade diesel in the cold season.
How it works
As temperature falls, paraffin crystallises and clogs filters and lines.
Why it matters for your car
Do not add petrol to diesel as an anti-gel; it can damage the injection system. Park in a warmer place and use approved additives if needed.
