Re the direct injection comment.. one small trick can save you $300 on engine flushes from carbon buildup: you can get an oil catch can installed for under $100 that solves this problem.

But you can’t argue direct injection is worse than older fuel injection. You save more gas, get better performance (even though you don’t get as many valves), and have a cooler running engine with direct injection. That’s a net positive for the environment and your wallet over the life of your car
