Engine oil PENNZOIL or OEM Mazda

I use Penzoil Ultra platinum 5w20 and a Mobil 1 filter. No issues so far, but I'm just closing in on 100k miles.

Pennzoil Platinum or Ultra Platinum 5w20. Good deals on it ordering from Walmart and usually free next day delivery.

Wix 57060 filter

I am tuned in WI and running Pennzoil Ultra Platinum 5w-30

Fuck Mobil 1. Get you some penzoil ultra platinum or better yet some amsoil. They’re both miles better than Mobil 1. I used to use Mobil before switching to penzoil. The difference was noticeable

I use Full Synthetic ( Pennzoil Platinum). At 24K I really can't even tell the engine is running when I come to a stop, its just that smooth and quiet.

Pennsoil Platinum High Mileage 0W20. It seems to run best on it, at least among the wal mart oils.

Could be weather related. I'm in Canada and we have weather from -35C to +35C, so Mazda recommends oil changes every 8000km instead of 12,000km.

I use original Mazda oil and Nipparts for the filters. I live in Europe and I buy these for 80€ / 85$.

I’ve used pennzoil platinum or ultra platinum on my 8th and 9th gen si. Never burns a drop in the 3.5k mile interval changes and I beat the thing like I stole it most days.

I use full synthetic all the time, either Pennzoil Platinum or Mobil 1.
