So I think its time for an engine Rebuild, and while searching the internet i read somewhere to use oversized pistons 83mm. My engine is a BWT with standard 82.5mm pistons. Will it make since to use larger pistons?

Strip it first and see how the bores look before spending your monies it might guide you down a different path

They have a lower compression ratio, would it make a difference?

But the engine will be less ‘efficient’, lower mpg, higher CO2 etc

Did it help with the oil consumption issue?
