Thinking of switching to a diesel car

[CrgT16]

Changing cars rarely saves money if you take into account the cost of the new car. (assuming current car has been paid for)

Also the mpg depends on the roads driven and how you drive.

I do many miles on my car and they are motorway miles. My 1.5T petrol does 45-50mpg and that works for me. Diesel would probably be better.

Well the OP says he has done the sums, but we are yet to see them................................

deed is done, test drove the diesel this morning and it is a lot more comfy to drive and my passenger preferred it.
thanks for the comments.

I do very few miles but I have two Diesel cars, one is a V8 and it's a lovely engine.

You don't need to see them as long as it works for the OP that's all that matters.

^ Oh, I'm too late then!
But since you asked,
yes there is a reason not to do it. It's called driveability.
Modern diesels are a pain, the torque/power is all wrong if you're used to a petrol.
I have both available and I prefer the old petrol. Even taking into account the improvement from 33mpg to 56mpg.

Did you read the original post ?

Yep I did & I also read the following posts.

The OP had already had diesel Stelvio so knew the answers fuel economy/running cost wise, he was actually worried about going diesel because of possible legalisation etc.

Hi,
we are thinking of switching to a 2019 diesel (euro 6) SUV to save us some money, currently getting 25 mpg being really careful we will get better mileage (45), we will be keeping for 3-4 years, possible more depending on how things go.

Is there any reason not to do this?

cheers

I've had petrols for years, within the last 9 months have gone to diesel for me and the wife.

Wife had a 2021 Peugeot 1.2 2008 petrol, she was doing low milege and getting 33mpg at best, I'd use it for work on a decent run and get 44mpg tops, always fancied a 6 cylinder diesel so got her an E93 330d, it does 35mpg round town but on a run much better and is so much nicer to drive although being 11 years older.

Other car is a transporter T6, petrol are like hens teeth and do 18mpg so had little choice in that

Why do so many people needlessly put/say "going forward" at the end of a sentence these days?

It's rife at work. At least it adds some interest to Teams meetings. The "going forward" count up.

i might start doing this going forward

Depends where you are driving? I find diesel is better for 95% of every day driving in terms of driveability. Only Bev/Hev are comparible.

The advantage of the lower down torque works even better when you get into smaller engines.

The only downside for a modern diesel is that you have about 6 sensors+ just in the exhaust system which increases the likelihood of one failing. Especially if Mercedes

It depends on the engine and mapping but I just swapped a daily turbo diesel for a small petrol turbo petrol and it basically drives like a diesel with some extra revs.
