My diesel is doing getting a low fuel economy, should I add an additive?
I just got a diesel 2018 Honda Civic with just 4500 miles on it. I'm only getting 39mpg. Should I put a fuel additive in?

That's very low mileage for a diesel. The mpg is most-likely caused by extra fuel being injected to force the DPF into an active regeneration. The car needs more miles, not a fuel additive.

Bigger than previous Civic, independent rear suspension means better ride and handling, 1.0 VTEC turbo petrol is excellent while i-DTEC diesel is very refined.
