You need to clean up your act over diesel.

IN MY not so humble opinion, diesel is the devil’s work.

We were told it was cheaper than petrol, took you further by miles and was the panacea for motoring ills.

OK, so your car sounded like a black cab but it was a better fuel – we could cope with that.

Then diesel became more expensive than petrol and petrol engines became more efficient, increasing the miles per gallon achieved, and questions started to be asked in some quarters about diesel’s long-term future.

Then the death knell was delivered. The World Health Organisation said diesel exhaust fumes are carcinogenic. They cause cancer.

I won’t waste column inches on certain manufacturers who cheated on emissions. You know the score there, eh?

That tell-tale black trail of yuk that pours out of countless vans and company cars causes lung and bladder cancer.

That smoke is full of particulate matter, tiny particles of soot, smoke and general grottiness that is a killer.

Diesel cars are all fitted with a diesel particulate filter or DPF to reduce the amount of harmful stuff that leaves the exhaust.

The filter works best at high temperature, when the particles filtered out are burned at high temperature – where cars are doing long journeys on faster roads.

Unfortunately, a large number of diesels are used almost exclusively for the short school run and to pop to the shops.

The filter can, over time, become clogged and less effective and, without a good burn, will eventually lead to a light alert on the dashboard.

This needs dealing with, pronto.

Some companies offer to remove the DPF to overcome the blocked filter but this may lead to the vehicle being deemed illegal and could cause your car to fail an MOT.

You’d be better to visit a company such as DPF Deep Clean, in Grangemouth, who will clean your filter and fully restore it to its “as new” condition.

They can deal with all diesel vehicles from a Ford Fiesta to a truck, saving you money and making your drive less deadly.

You see, every devil can have a silver lining.
