I am considering selling my 8th generation Civic to buy this:

Downgrading from 1.8L to 1.0L. I'm concerned it will be underpowered.

Think I'll keep my MK8 Civic for a few more years. Its done 146 000 miles. Starting to age. But its running smoothly like the day I bought it.

If you want the reliability and similar performance to your civic 1.8 , I suggest the Mazda 3 2.0 petrol.

Early 1.5 turbo’s had oil dilution issues.

Supposedly an overblown issue which has primarily impacted US buyers as opposed to European

My inlaws had a 1.0T wet belt failure last year, fortunately engine replaced under warranty (after the whole "you need to pay us £x thousand just to diagnose it and we'll refund if it's a wet belt induced problem" bks...)

Yes it is a stupid design. Belt wears, rubber particles end up in oil, then presumably it doesn't go through the filter before going into the turbo. Turbo oil feed clogged, turbo overheated, lunched itself, metal ended up in the cylinders.

Slight thread revival, but the key points I would want to stress -

Don't go for the 1L If you plan to keep it.

The aforementioned wet belt adds hugely to the upkeep and service costs, with scheduled changes being upwards of £1k

The reliability is poor, thanks again to the wet belt - There's been a number of failures and friends who work in service at Honda have seen a great number of them back for new engines

Finally, The 1.5 has better real world fuel economy, more power, and greater reliability - The oil dilution issues have never reared their heads in Europe that I've seen, and were primarily a north US / Canadian market concern, where people are making short drives in negative temperatures on a very regular basis.

Whatever premium you'd pay for the 1.5 over a 1L will very quickly be made up for by the increased service cost, bork factor and fuel consumption.
