Spark plug OEM BMW or OEM Mazda
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.
Pros: still started and carried
Cons: piss poor compression numbers
Vehicle:
Mazda
Mileage: 30000 km
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.
Pros: easy to replace
Vehicle:
Mazda 3
Mileage: 120000 km
I bought my 2019 330i in 2022. It was a lease return. While basic maintenance items are a lot more than, let’s say, a Toyota, it has been far from a money pit. I have put 50k miles on it in the three years I’ve had it, and had nothing out of the ordinary go wrong. Spark plugs, brake pads, air filters, tires, oil changes, that’s it.
Pros: nothing out of ordinary
Cons: maintenance items pricey
Vehicle:
BMW
Mileage: 80467 km
It is, I have a 2020 330xi with 80k miles. It runs like a champ. Make sure you change out spark plugs. Most people don't. NGK's come with the car.
Pros: runs like a champ
Cons: spark plugs
Vehicle:
BMW
Mileage: 128748 km
The tools aren’t expensive. Yes I use dielectric grease but not anti sieze on the threads (only because BMW orders us not to). Easy job for most cars.
Pros: tools aren't expensive, easy job
Cons: BMW orders not to use anti-seize
I bought a 19’ Premium at 17 it’s a great little car beat the shit out of it for 4 years straight and it runs amazing still. Handles well in the winter as long as you have clearance it’ll get you there in one piece. Regular maintenance along with trans fluid change, spark plugs, brakes, diff fluid change. I’d recommend a cpo premium . Great value.
Pros: runs amazing, handles well
Vehicle:
Mazda 3
I would recommend that if you get one do a full service fluid change on everything. Change the coolant, the trans fluid, diff fluid, oil (10w30 or 10w40, do NOT use the 5w20 reccomended). You'll also want to set aside $80-90 for new spark plugs, and upgrade the coil packs to LS coils from Bennet Built whenever you can. Coils need to be replaced about every 30k miles.
Pros: strong rotary, mechanically inclined
Cons: everything is breaking, plastics dry
Vehicle:
Mazda
Mileage: 73000 km
I just completed my first spark plug change on my G20 330 at 40k miles. Three of them especially Cylinder 1 came out "wet" and I'm unsure if it's oil.
Cons: wet spark plugs
Vehicle:
BMW
Mileage: 64373 km
If you are willing to put some money into it before resorting to drastic measures, try replacing all 6 of your spark plugs and ignition coils. Might help in your case, or it might not.
Pros: might help
Cons: might not
Vehicle:
