New Car - Diesel v petrol mileage threshold
Discussion
Hi, I need some advice on a new car purchase. In the next month or so I need to buy a new (to me) car. I've settled on a 2009 year Mazda 6 but can't decide on whether to buy a Petrol or diesel model. The options are 2009 2.2d Sport 185bhp or the 2.0 petrol TS2 145bhp.
This will be our main family car but it will be mainly driven by my wife, however we car share and use my car for commuting to work and back so it really will only get driven at the weekends and evenings. Annual mileage on this car should be about 8000-9000 miles.
The petrol car is cheaper to buy, but £60 more a year to tax and won't be as economical as the diesel but as there is roughly £2.5k difference in the purchase price i'm thinking that would buy alot of petrol to make up the difference in the fuel economy.
We've always had diesel cars since 1992 but i'm thinking on this one the maths make the petrol car a more viable option.
Whats your opinion on this?

The 8000-9000 miles will mostly be A and B class roads in NI with the odd motorway journey in the mix- very little town driving.
I'd be hoping that the petrol model would be averaging 36mpg plus and the diesel 43mpg plus.
We haven't had a petrol car (except for the mcrae) since 1992 so i'm struggling to make the decision on this purchase.

The diesel Mazda6 suffers quite a few issues, DPF, fuel pumps, injectors, its not a good lump! (its actually a Ford Mondeo engine)
Go for the petrol one for sure, you'll have heating on short journeys too, or if diesel don't buy the Mazda!
I thought most of those issues where on the 2.0 diesel model and not the 2.2 diesel. New diesels seem very complicated- if i do go for the diesel i'll be making it a condition of the sale that i get a warranty on the DPF.Go for the petrol one for sure, you'll have heating on short journeys too, or if diesel don't buy the Mazda!
We are about 20mins from our work, her parents and large shopping town so the car would typically be doing this length of journey at the weekends.

£2500 is going to cover the reduced MPG of the petrol for about 5-8 years, that is assuming the real world MPG is actually that much different, let alone factoring in the cost of a DPF on the diesel and the fact that diesels really dont shine on short trips.
My previous 143BHP TDI acheived a real world mpg of about 40 ish doing daily 12 mile commutes over A/BRoads, my current 260BHP Petrol achieves real world of about 35MPG (if i dont abuse it) and petrol (even VPower) is cheaper than diesel. And the petrol is blowing warm air at me within 2 minutes rather than just before I get to the office which is actually a huge plus this time of year.

Diesel is 185bhp, petrol is 145bhp - diesel 
That's another point to consider, on our roads we need a car that can complete overtakes easily- too many tractors, 4x4's towing livestock trailers & horseboxes and 40mph lovers. I'm thinking the extra 40bhp and the 40-70mph time on the 2.2d would better than the 2.0 petrol.Its the £2.5 difference in the purchase price and the higher price of diesel at the pumps that is causing me to look at the petrol model in this instance.

You may well get the bulk of the £2.5k premium back when you come to sell it on, so factor that in too....Its the £2.5 difference in the purchase price and the higher price of diesel at the pumps that is causing me to look at the petrol model in this instance.

The 2.2 is probably the Ford TDCi as well I've have thought? Used to have one in a ST TDCI Mondy and cost me an absolute fortune in repairs. Ford's TDCI engines are known for being unreliable pieces of junk though, pity I didn't know that beforehand.We are about 20mins from our work, her parents and large shopping town so the car would typically be doing this length of journey at the weekends.
But to the OP, for the miles you'll be doing, defo a petrol. As others have mentioned, no DMF, DPF, EGR or injector issues, and trust me, you will get them doing that sort of mileage.
