Engine oil PENNZOIL or OEM Mazda

SP certified oils have better LSPI protection than SN, and SP is what Subaru requires for this generation.

I use PUP 0w20 in mine. Lots of tests and UOA show that Pennzoil Ultra Platinum is the best non-boutique oil you can buy. But honestly any top shelf oil will work. 5k km intervals are more important than brand with a turbo engine.

Do her a favor a change the oil, with Valvoline Restore and Protect or Pennzoil Ultra platinum, it will quite down a little and it would be great for the car.

No, but I did keep 2 quarts of oil and a gallon jug of water. My Mazda Protege was notorious for burning oil and overheating

Pennzoil Platinum Synthetic. My 1988 740 has near excellent compression at 245k og miles.

At the very least, make sure you're using quality oil like Mobil or Castrol or Pennzoil.

I prefer synthetic myself in my CX50 Turbo, but Mazda engines aren't very picky overall.

I use Pennzoil Platinum 5W-30 in my 2011 328ix (N51) I believe that is the recommended viscosity.

zu viel Kurzstrecke. mach mal nen Ölwechsel und lass den wagen dann mal richtig auf Temperatur kommen.

they only say you can do that with their Mazda-branded oil. That stuff tends to be expensive.
