Is red diesel bad for my car?
Red diesel is chemically similar to normal diesel but it's illegal to use on the road and the dye can flag up in checks. If it's gone into a road vehicle, it should be drained and the system flushed.
In an emergency: don't start the engine and call 0800 170 0644. We drain the wrong fuel on-site, 24/7, 365 days a year.
