Fiancee has the 1.5T in her 2018 Civic Hatchback with the 6MT. She's had it since October of 2018, and now has about 26,000 miles. No problems, and dilution doesn't seem to be a problem (I do her maintenance and I've been watching the oil level). But her commute is at least 15 miles, one way, every day. We also don't live in a really cold part of the country, and we do pretty frequent out of town trips. I change the oil every 5000 miles, using a good synth.
I also try to rev it a bit when she lets me drive it. I think that helps. As Olas was saying, I don't think it's too good to lug these modern, TGDI engines. Better to rev them a bit, instead of mashing the gas pedal in a high gear at low RPM and counting on the turbo boost for torque. That creates ideal conditions for LSPI and fuel dilution due to the ECU compensating for spikes in cylinder pressure/temp with overly rich mixtures.
It seems counterintuitive; Most people think it's good for an engine to live at lower RPM. But, for a small 4-cylinder, especially TGDI, I think it's easier on the engine to let it rev a bit. Let it live in the range where it makes easy power.
Anyway, it's a good powerplant. We'll see how long-term reliability for ours does, but it's an enjoyable engine in her Civic. 174 HP gets it down the road very well, especially with the broad torque spread. And it has tons of cargo room with the hatchback.
I believe the 1.5T in the Accord is a different spec than the one we have. I think in the Accord, it's the same engine as what's in the Civic Si, which is 205 HP, I think. So, about 30 more than hers. Should be a nice engine. I can promise you it'll be a more entertaining drive than the Camry. I suggest getting the 6-speed. Honda has always made a great manual gearbox. The 6-speed in the fiancee's Civic is a joy to use. Clutch is very light, with good engagement feel. This is her first manual car, and she's had no trouble learning it.
