Skyactiv engines are direct injection. Might want to look at adding an oil catch can to prevent build up in the intake valves.

To reiterate, I'm not bashing Mazda. The FD RX-7 is one of my top 5 all time favorite cars and I'm a fan of many of their models. Having said that, more recent models and designs haven't been my cup of tea and I haven't heard great things about the 2/iA, specifically.

To me the IA/2 is just a money maker for toyota, people will buy the toyota nameplate but toyota corporate trusts mazda's engine design and in the end the general populus feels good, both companies are being paid, and both toyota and mazda can shit out their beloved "car enthusiast" stylized cars

also their RX cars where phenomenal ;) I owned a few haha

Bronsin , make sure your son in law uses a Top Tier gasoline for the Yaris Ia at all fillups . It's highly recommended for D.I engines . Here's a list of Top Tier gasolines . https://www.toptiergas.com/licensedbrands/ . The use of TOP TIER gasoline is likely in the owner manual . Have him look it up . Its stated in the '11 FIT owner manual ( below ) . The FIT is E.F.I. .

All good information thanks!

Basically any gas station you encounter are top tier.. mobile1, Sunoco, esso...

in my area we have a lot of MurphyUSA stations(walmart pumps) and i personally use Kroger fuel(grocery store) due to the points i get from shopping there saving me $ on gas.

somebody a long time ago told me all gas was the same and they get them from the same refineries. i know BP adds 'invogorate' and Shell i'm sure does something because it's always the most expensive. sorry to get off topic on my fuel statements!

With pure direct-inject engine designs (like Mazda uses - and most other automakers for that matter), even top-tier gas will only address HALF the carbon buildup/deposit problem. They are simply flawed engine designs from a reliable, problem-free consumer ownership standpoint. Direct injection needs to be paired with port-injection to address the whole issue adequately, with regards to top-tier fuel detergents keeping carbon deposits at bay across BOTH problem areas. Toyota was smart enough to do just that with their new TNGA 2019 Corolla engine design. That's also another reason to LOVE the venerable non-direct-injection 1NZ-FE engine still being used in the Yaris.

An oil catch can should keep the intake valve pretty clean.

Shouldn't Mazda (& others) be doing that from a design & factory-build standpoint? It should be standard equipment for straight GDI engine designs, if they care anything about building a reliable, trouble-free engine that stands the test of time.
