vs
Engine oil Motorex or IDEMITSU
It works great, maybe a bit expensive. I've run used oil analysis and change it 3-4k miles based on aluminum wear. I don't see a reason to use something else.
Pros: works great
Cons: a bit expensive
I use Motorex semi-synthetic 4t in all of my KTM's over the years in a 15w50 weight. It has never been an issue. I have used Motul 5100 and 7100 in other bikes before, and I prefer the 7100 over the 5100. It feels like the bikes perform better when the temps rise and I'm really riding them hard.
Pros: bikes perform better
I have a Sohn kit and run Idemitsu engine oil in the engine and Idemitsu premix in the Sohn. Runs lovely and smooth and the original cat is still doing the job.
Pros: runs lovely and smooth
Vehicle:
Mazda
We use Idemitsu for engine oil and transmission and red line for front and rear diff. Red line makes a good fluid for the transmission also.
I use Idemitsu Wankel Racing Oil. 10w30, I think.
Pros: Wankel Racing Oil
Vehicle:
Mazda
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
Idemitsu all day. It’s synthetic but what needs to be emphasized is the ingredient blend is purpose designed for a rotary to make the right lube + burn.
Pros: purpose designed for rotary
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.
Pros: Motorex was the best
Cons: Shell not always available
Mileage: 34000 km
I've been running that exact oil in my rx8 for about 1k km now and its still as smooth as ever
Pros: still as smooth as ever
Vehicle:
Mazda
Mileage: 1000 km
It takes a “synthetic blend” of motorex 15W50 oil. And uhh yeah works good I guess, don’t have to change it too often, and as far as performance goes, it doesn’t really matter because I’m on restricted power anyways so yeah ????♂️
Pros: works good
Cons: restricted power
