For someone as defensive as you are, you might want to be a bit more open minded to suggestions as a few of us have a bit more experience with these cars than you do.
For starters, if you want your 1.6 to last toss the 5w30 in the trash and switch to a good 5w40 synthetic. This has been a TSB with Hyundai regarding the TGDI engines for years, and for good reason.
Second. Catch cans should be your first mod as a preventative maintenance measure. But, that’s up to you and your wallet.
Well hello to you to, I hope you’re having a fantastic day.
I just don’t really care about the opinions of forum members who claim to have vast experience but are collectively a fraction of a percentage of owners with this car and an even smaller fraction that have experience with this engine.
Meanwhile, I have 3 current generation 1.6Ts, each of varying age and mileage, all receiving the same treatment and all with a clean bill health and while that no way makes me an expert on this engine, it also doesn’t mean I have no experience and also doesn’t give me the right to tell other people with the same car/engine how to maintain theirs. But you folks are hilarious so please continue on telling other members what they need to do with their own cars. It’s one thing to make a suggestion based on experience or even personal preference but it’s another altogether to force your subjectivity onto someone else.
In my climate and with my driving style, it’s unnecessary to run 5w40. The warranty is lengthy, and beyond that, I can handle whatever repair related issues arise.
I handle my own maintenance, keep detailed logs, check oil levels periodically, change the oil far sooner than I probably should and get UOAs religiously.
This isn’t my first or second car. It’s the 3rd being added to the stable and will be driven sparingly at most, 5 months out of the year.
Catch-can or not, the intake tract will gunk up. The catch-can may slow down the process, even though the data on that is dubious at best, but it’s not going to stop it and it’s not 100%. It’s a nice to have but certainly not a necessity. I also clean my intake tract, including the valves, after about 20,000 miles on a DI motor. So once again, maintenance that I handle so a catch can may be added at some point but I’ll just end up cleaning the intake anyway. But once again, continue to tell me how I should be maintaining my car.
