Got my 2019 Civic 1.5T to 93k miles and sold it this fall. Great car. Probably had some oil dilution because dipstick level would creep up. No CVT problems (drain and fill were done at 45k & 90k). Replaced plugs at 90k as well and they looked good although there was a little oil in cylinder 3. Ran great, no codes, high quality oil changes every 5k.

Pros: Great car, high quality
Cons: oil dilution
Vehicle: Honda Civic
Mileage: 149669 km

Bro ABSOLUTELY do the spark plugs yourself. I bought oem Denso spark plugs from Napa Auto for about $180. Then all you need is a spark plug socket w/ swivel head, 10mm socket, 12mm, a couple extensions, needle nose pliers, dielectric grease, and a pick to make life easier.

Pros: save money, easy job
Cons: time consuming for beginner

Swapped the NGKs (around 60k miles on them) for new OEM Denso plugs. That stopped the shaking for about two days, then it came back.

Pros: stopped shaking for days
Cons: shaking came back

I’ve had several Denso plugs do this on a couple Camrys I service, and our own. All 2.4 cars. Caused tow ins for both husband and wife’s cars. I’ve fired denso as a spark plug provider, too many failures.

Pros: null
Cons: too many failures
