Small fuel efficient diesel engine for engine swap?
TMB - 12/7/22 at 06:41 PM

Is there a good option out there?
Must have a very good fuel milage to make the list.

Some says the Honda 1.6 D-tec. But its a problem with the wiring and system to get it running without its donorcar.
Pegout 1,6 Diesel is also a good engine, but the consumption start increases when the milage is high. (so best as new, not used)


Any good advices?

how much are you going to use it?
a car that does 25mpg will use ~twice as much fuel as one that does 50, but look at the numbers
if you are doing say 2,500 mile per year. then chose an engine that suits.
if doing 250,000 mile per year, then, yes, you need the most economical.

The Renault 1.5dCi unit gives around 70mpg in the Captur

I had the same engine (tho' I think it's a slightly lesser spec) in the Dacia Logan, 24,000 trouble free miles & averaged at nearly 60mpg including all town/traffic & motorway driving. No idea how easily the engine transplants, but given the Logan & Sandero are relatively basic compared with the Renault offerings I can't imagine it would be too onerous if you went for one of those

What vehicle do you want to put the engine in (layout, size, weight etc)?

Might help people on here figure out the best opitons for you.

Really can't understand why you'd opt for a diesel. The fuel is super expensive, they have higher maintenance costs than a petrol engine, the government hates them now, so expect taxes and restrictions only to increase. Yeah they have their place for things like towing and loooonnngg distance driving but it's on it's way out.

Have to say I agree. Having been a big mile driver in company cars (30k+ / year) I loved diesels. In fact it was a stipulation for company cars, diesel and 4 door. However...

1. Diesel was nowhere near as pricey as it is now
2. Company car so I wasn't paying for maintenance

Our private cars were diesel for a good few years as well. Just switched back to petrol and the maintenance costs are noticeably less.



To the OP I go back to my question of what vehicle are you wanting to put it in?

Depends what country you're in. In the Netherlands, diesel is 1.95 a litre and petrol is 2.20 a litre.

Either price is dear - I recall people moaning when it hit £1.40 a few years back. I was driving a company car at the time and having to drive with a light right foot and some "mileage compensation" to get inside the allowed pence/mile claim rate set by the govenrment.
