Are 10th gen manual Honda Civic Si (2017+) with 1.5L engines reliable?

I came to know that they have both turbo and GDI, which sounded like a red flag to me.

Do they suffer from oil dilution problems? 

Thanks!

Yes, the 1.5 Turbocharged engines w/GDI in the Civic, Accord, and CR-V lineup suffer from oil dilution. 

Being on this forum a while I can tell you compared to other competitors it is the more reliable one. The manual transmission is basically bulletproof. But unfortunately the engine is laughably tiny and is high-pressure so it in itself isn't that reliable.
