Hi All,

My wife and I are looking to buy an X5 / X3 / Touarge type car. Looking at 2006 cars with approximately 50-60k the going rate is about 11k in diesel formate. However the petrol equivalents are about 8k. So naturally we should go for the petrol, however diesels hold there money better - we'll they do currently!

So based on my wife's annual mile of around 10,000, which fuel type should be go for.

Calculations or just opinions would be much appreciated!

Don't forget petrol is a cheaper fuel also so ignore MPG and look a MP£.

Also a petrol less likely to explode in a pile of cogs and springs

The annual savings in fuel will be £300-400. But I imagine a £11k diesel will lose more money per year than a £8k petrol.
Swings and roundabouts.

10k miles a year you'll very likely be better off in the petrol. Depends on the real world mpg you'd get out of your chosen engines.

We have a 3.0D X3 MSport 2007 facelift and its fantastic for touring. Can load it up big time and hardly notice
The turbo D mates so well with the 6 speed auto.

Note BMW improved the power and economy in '07.

Also, we keep up the manufacturers extended warranty (only £420/year) just in case.

Anyone who thinks they can buy an expensive car new (40k) for beer money and run it cheaply is taking a gamble. Better make it a calculated one.

Look not only at mileage but what type of journeys. A few short ones and the occasion long journey? Petrol. Mostly over 20 miles? Diesel probably better. As above though, BMW diesels certainly took a leap forward in economy terms in 2007.

Great input, thank you. I guess the real stumbling block for me is rasiduals. Petrol 4x4s are very cheap, and I doubt many people are buying them - and as much as maybe petrol makes sence for us, I feel we will stand a better chance of selling the diesel model on again in a few years time. With petrol models, we'll be giving them away at this rate...

what's the difference in service costs/schedules?

Few years ago at work we stocked a large amount of X5's, all diesel other than 1, it was a well spec'd, low enough miles at sensible money. But it just didn't go, all the diesels would sell no trouble even in their dog form. Maybe we were just unlucky, but it did seem much harder to sell a big engined 4x4.

I've done the calcs a few times, and I rekon you need to be doing at least 12k a year, pos a little more.

As others have said look at the type of journeys too - Dervs hate short journeys where they dont get warmed up.

At 10k a year, and with the petrol being 3k cheaper I would go petrol.

Added to that, you need to look into things like DPFs and DMFs - does the engine have them, are they an issue for the driving that will be done? Pottering around town is exactly what diesels don't like.

I used to commute Oxford/LHR. I have run diesels for a number of years. Now that I have retired, the mpg is not too good on our short 'shopping' trips, about 35-37mpg. However, in order to keep the dreaded DPF clear, we visit our daughter and family in Bovingdon every two weeks. The blast on the M40, M25 and a bit of the A41 keeps the DPF clear. The current Saab is an auto, and the mpg on those runs is 45-50 depending on my right foot. The car has done just over 57k, runs as sweet as a nut, and pulls our caravan a treat returning 25-30mpg towing cruising at 60.
Well chuffed with our diesel motoring. However, if we didn't have those fortnightly runs, I would go for a petrol no question.

Your price spread will leave you with wrong data.
Try and average of 9k for a petrol and 10.5k for diesel, then you'll find the oil burner cheaper.

At that kind of mileage and age i'd suggest that a petrol is the best option on purely cost terms. A diesel might be better in a heavy 4x4 though.

It's a high price for visiting Hemel Hempstead though...

Jokes aside, I reckon the OP needs to be doing a good 16k a year to justify the diesel. Repairs are more costly, and seemingly more common.

My wife does 12k a year and we opted for Petrol over Diesel. I do 35k a year and do it in £800 worth of Petrol car, because £800 worth of diesel car wouldn't certainly come with problems.

Interesting thread. Could the demise of diesel be on the horizon due the more frugal petrol cars and the pence per litre difference currently between the two?

I had a Hyundai hire car this week (petrol) and on a 543 mile trip returned 52.4mpg and that was with some spirited, ahem...."hire-car" driving. Rather impressive I thought.

Begs the question why it seems the UK has higher diesel prices than petrol when on the continent diesel is generally cheaper.
