A top car mechanic has warned diesel owners could be at risk of developing major issues with their fuel system by failing to regularly use additives. 

Leading expert Scotty Kilmer stressed that “mould and bacteria” could grow inside vehicles in a major concern for key components. 

Using fuel additives can help maintain vital parts such as the carburettors, injectors and intake valves meaning vehicles stay in top condition

Additives can be purchased at most high street motoring stores and online often for less than £10.

The top mechanic revealed the super important tip after he was asked by a viewer to rate the importance of using additives in their vehicles.

They asked: “Scotty, what do you think of fuel additives? I use Liquid Moly in my 1.9-litre diesel, works like a dream every time."

Speaking on his YouTube channel, Scotty replied: “You've got a diesel. It's a good idea to add fuel additives once in a while to a diesel. 

“Diesel fuel is a lot different than gasoline. Diesel fuel actually mould and bacteria can grow in diesel fuel. It's not as caustic as gasoline. 

“You never want that to happen so with a diesel it’s a good idea to put additives in once in a while.”

Scotty stressed most petrol already contains certain additives to ensure motorists secure better mileage and the compound doesn't pollute the environment. 

It means owners of some petrol models “really don't need to put any additives in” except in certain situations. 

Scotty stressed: “Now if you've got a junky old car, say you've bought a used car and the fuel injectors are clogged up, yeah there are some good additives you can put in. 

“Just make sure with gasoline engines you do ones that have P.E.A, they say contains P.E.A. It's a nitrogen-based cleaner that actually works, that all the really good cleaners have.”

Fans on YouTube quickly took to the comments section praising Scotty for his advice and handing out more first-hand tips to confused motorists.

YouTube viewer @nigelcharlton-wright1747 said: “I wish I knew when I had a diesel-powered Jaguar. 

“The DPF filter needed to be replaced, would have cost a lot of money to replace. Should have used an additive! You are a very knowledgeable man.”

@brandonburley3080 added: "Also...many diesel injectors and injection pumps are very sensitive and require very clean diesel fuel, and rely a lot more on the fuel itself for lubrication. 

“And modern diesel fuels don't have quite as good lubricity as they used to, so many fuel additives also help make up for that.”
