Is a petrol car better than diesel for short journeys?
Am I right in suggesting that it's better to use a petrol engine rather than a diesel for short journeys on a regular basis for example only doing 20 miles a day and not really exceeding 50mph? I was thinking of the EGR possibility clogging up.

Diesel cars with diesel particulate filters fitted can suffer problems when used for frequent short journeys as the lack of extended driving at a constant speed prevents the DPF from being able to regenerate. In truth, frequent short journeys are less healthy for all kinds of cars - with the possible exception of EVs - but you should experience fewer problems with a petrol than a diesel with this kind of driving.
