I'm looking at buying a new car. I currently have a diesel that I get 52.3 mpg overall, I have to work out my costs each month so I know that's very accurate.
If I purchase a Petrol I'm going to get lower mpg but the cost per gallon is cheaper as well.
I have to make some assumptions, but assuming petrol is 10p per litre cheaper over 6,000 miles how much could I drop to in MPG for my costs to remain in the same ball park.
As you may guess maths is not my strong point
Avoid a NEW car. Too much depreciation.
The question you should ask yourself is what type of mileage are you doing? Newer diesels don't like short journeys/low mileage due to the technology that helps keep them clean; DPFs, EGRs, AdBlue, etc. Avoid a wetbelt engine if possible or do more oil changes than recommended if you do get one.
You'd need a petrol car that can do 50.2 mpg. (Using the current average; Diesel being £7.40/gallon and Petrol £7.10/gallon).
Long time ago since I went to school, so maybe someone else can calculate to confirm.
And those are the polluting, probably high mileage, knackered ones that they want off the road. They are probably costing their drivers a lot to run in terms of road tax, fuel costs, servicing, so it makes sense to replace them not just because of ULEZ.

Wrong. I've just updated my Euro4 diesel to a later (same manufacturer and model) Euro 6 diesel and getting 10 mpg less. Every 1,000 miles, I'm paying about £30 more for fuel; for me that's another £360 extra per year.
I might be saving £40 on car tax per year but I'm paying at least £40 more for service items. Tyres will cost more too as they are wider/lower profile.
