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.
On my Honda Fit that would be an excellent price because you have to take off a cowl to get to the plugs.
Just did mine at 69k. Felt like a small pickup in performance.
Bought a used 2014 CX5 with like 250km on it. Changed the spark plugs the second I bought it. Now THOSE were due.
I’ve had my cx5 since August of 23. Put 48k on it since owning it, bought used at 44k it’s been a dream come true. cx5 just takes regular maintenance like oil changes spark plugs and brakes..and another plus it’s a very sharp looking vehicle inside an out.
Spark plugs, coolant exchange, transmission drain/fill, brake fluid flush, and air filter replacement, stat.
My RX8 also got pretty piss poor compression numbers. The only time it struggled with a start up was with literally the original 20 years old plugs it came with and I had to do multiple hot starts. It still started and carried on.
At around 120,000 KM plan for spark plugs. It's easy, especially if you get a 1/4" torque wrench and 14mm 1/4 deep well socket.
That price at 63.5k miles isn't bad imo. I spent roughly that same amount for my 2017 back in 2019 with around 40k miles (64k km). What's the service history look like? Have spark plugs been replaced, belts checked, engine oil changed at least 10-12 times by now? How are the pads and rotors?
struggling to home diagnose what’s wrong with my 2015 Honda Fit (around 160k miles). Worked fine 2 days ago when I last used it, Went to turn it on this morning and it sputtered then stopped. Red oil light came on, red battery light, and orange power steering light showed on dash. Brake pedal locked up. We changed the oil, checked battery life (at 70%), replaced spark plugs and alternator coils (needed new ones anyways), and it’s STILL not starting.
