Should I choose petrol or diesel?

Hi guys,

My question has two parts. Firstly I am changing car and always drove a diesel but am wondering about improved economy of modern petrol engines, e.g. VW Jetta 1.4 TSI vs.  VW Jetta TDI. Maybe you can advise what criteria I should consider?

Also, as my mileage is difficult to predict, I am concerned that if I am not doing enough miles I will have problems with the particulate filter on a diesel. What do you think?

Why is my Passat's economy so poor?

Hi, we recently bought a VW Passat 1.6 FSI, but the fuel economy is terrible. We seem to be at the petrol pump more often than not. Is this common for this type of car?

When did diesel particulate filters come?

Could you tell which were the first diesel cars on the Irish market to be fitted with diesel particulate filters (DPF) as standard or even as an option? We're looking for a 6-8 year-old car and would like to consider a diesel for cheaper running costs, but a DPF is a must because of our concerns over how diesel soot particulates can cause asthma. Preferably at least medium sized or mini-MPV.

BMW 520d auto versus manual?

Can you give me a rough idea what the mpg difference would be between a BMW 520d automatic and 520d SE manual version for mainly suburban driving.

I know that for resale automatic is better, but ecomony is important to me.

Also, the suspension for M Sport version is stiffer and firmer; I am not into fast driving, but do like the sport styling. Can you tell me is the ride comfort difference noticable?

How do I get better fuel economy?

Hi there,

I bought the new Opel Astra in January, a diesel 1.7L CDTi with 110hp. The car is well run-in at this stage with over 4,000km on the clock. I am only getting about 42mpg; the tank holds 56 litres and I am lucky to get 800km from this. The dealer has told me that it should be closer to 55mpg. I have a provisional appointment made with the dealer for him to do an emissions check on the car. Can you think of what might be causing the poor mileage considering I am not a hard driver and do obey the speed limit?

What fuel economy should I get in my 1.3 diesel Astra?

Hello, I drive a 2008 1.3-litre diesel Astra with a six-speed gearbox on a fairly normal driving pattern: start, stop, traffic-jams etc. and M50 motorway driving (in which I use the cruise control). What sort of fuel economy should I expect?

Thanks
