Engine oil OEM Mazda or Motorex

2014 3, 0W-20 full synthetic (whatever major brand is cheapest) from brand new, every 7500 miles.

170k, runs like a top, burns not a single drop between changes, compression and fuel mileage exactly the same as new.

I use Mazdas 5w-30 Ultra DPF. Mazda once said that this was the oil that they're using, so I guess what's used by mazda can't be too bad for the rex

Just came across this. Mine is a 2024 w 31 hours. I always used Motorex but I’m trying T6 this time. I use it in all my other off road bikes. In the 2t it’s just the clutch and trans. Also I’m changing it every 10 hrs

Ive used these. Motorex was the best. Castrol was pretty good, and Shell in case the others were not available. Now at 34k odo without problems.

I have always used Motorex. I have the same bike and 3 other KTM’s. Always Motorex. I know it is spendy but it’s very high quality

In my Shiver 750, Motul or Motorex every 3,500 miles were required to keep neutral findable when you want it and hidden when you don’t. False or impossible-to-find neutrals were a sign that it was time for an oil change.

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$.

Many reputable rotary shops have tested numerous oils over the years, and agreed that the bearings do not have adequate protection with 5w-20 or 5w-30, especially if you track the car or do any spirited driving regularly.

Mazda’s OEM 5w30 is a little too thin for my blood considering the engine temps when driving hard, fine if you’re going to never redline the car
