How to Drive a Diesel

[Alan gsd]

How should a diesel car be driven? Over the years by various 'esperts' I've been told to get the best and a long life from them drive them hard all the time others have said softly softly and still other softly most of the time but give them a good hard drive sometimes to clean the pipes out. So which is right please.

Generally a diesel engine needs to be run hard and they are governed to avoid over-revving so are safe to run fast

If the engine is not pushed then the carbon from burnt fuel clogs up injectors, EGR, DPF, inlet manifolds and this reduces performance and costs lots in repairs

If the engine is run at low revs then pushed hard in a high gear then this means the engine can usually deliver the power by way of the turbo but also causes the Dual Mass Flywheel (DMF) and clutch to slip, also costing money

The trick is to keep the revs high in the appropriate gear until you change up and if cruising on the motorway then fine to change up and lower the revs but at any opportunity to give it a clear out (slip roads are a favourite)

What's your view on injection clears you put in the fuel tank, any good??

Hi Alan

Some good advice as usual from Trevor, I also have a Mercedes e320 CD Avantgarde and concur with all the comments Trevor has made and exactly the case when on the Motorway change down the Gears and give it a blast through it seems to do the trick and keeps the Injectors clean which is the main problem sometimes with an erratic diesel engine not running smoothly, and a dose of Fortes Injector Cleaner helps as well

Gave my CRV a good run yesterday, to blow the cob webs out, did as you guys said, had a few puffs of black smoke and then it was clear and seemed sweeter. Today no black smoke 👏
