Engine oil Eneos or IDEMITSU

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.

I use only Eneos 0w20.

I normally use Mobil 1, but did experiment with a JDM brand called ENEOS. The engine seemed to run smoother with that engine than other brands I've tried before.

Eneos oil. Japanese full synthetic. Use it on my 96 accord. Good stuff.

I don’t use the Mazda-branded version, but Idemitsu is my go-to oil in all of our Mazdas

Eneos 5w-30! Car runs like a dream

Super happy with the guys at PIA, and they use Eneos 5w40.

My tuner recommended Eneos 5w40

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
