Which is why I'm not convinced smaller and more advanced engines are necessarily better. Even IF they were to get better fuel economy by a good margin the amount the owner will be spending on out of warranty repairs and even maintenance will mitigate any sort of savings on fuel. Modern engines have direct injection but as a consequence they get carbon buildup which a port injected motor does not get so there's money that needs to be spent. Then there's the turbos which have seals that eventually fail along with things like the wastegate not closing. Also, modern engines seem to consume lots of oil between changes so now you have this expensive oil being consumed which means clogged PCVs and more carbon buildup to deal with. They also have high pressure injectors that fail easily compared to port injectors. I'll keep my port injected, non turbo, non direct injection car for as long as I can.
