vs
Engine oil Kendall or IDEMITSU
I think Idemitsu is the better option if you have access to it. Mostly because it was developed for the rotary engine.
Pros: developed for rotary engine
Cons: hard to find
I use full synthetic kendall and it runs beautifully.
Pros: runs beautifully
Idemitsu to both, because it’s designed and tested on rotaries.
Pros: designed for rotaries
I use idemitsu rotary 20w50
I stick to Idemitsu. I have a Sohn adapter fitted, so it's 10-30 Idemitsu in the engine, twice a year and Idemitsu Premix in the Sohn adapter and in the fuel tank.
Pros: idemitsu in the engine
I don’t use the Mazda-branded version, but Idemitsu is my go-to oil in all of our Mazdas
Pros: go-to oil
Vehicle:
Mazda
Idemitsu is the only premix and engine oil I’ll use ... you can order it for a good price from TREx performance out of NJ and he will ship
Pros: good price, easy to order
The oil was Idemitsu Synthetic 0W-20 with 12.5k miles on it. Once again, trace metals and flashpoint were within normal range. I also ordered a TBN to measure the amount of additive left and that showed there was still plenty of active additive remaining.
Pros: trace metals normal range
Vehicle:
Mazda 3
Mileage: 12500 km
In terms of oiling, get a sohn adapter so your apex seals aren't being lubricated with crankcase oil, and instead are injected with rotary-specific oil, like idemitsu.
Pros: rotary-specific oil
Subaru OEM oil is Idemitsu 0W-20. I currently use Idemitsu Zepro\* 0W-20, a high-moly formulation from the same manufacturer.
Pros: high-moly formulation
Vehicle:
Subaru
