Engine oil OEM Honda or IDEMITSU

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.

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.

I have a Fit 2019 and switching from 5w30 to 0w20 improved my mileage from 650 km/tank to 800 km/tank.

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.

I've been running that exact oil in my rx8 for about 1k km now and its still as smooth as ever

i am of the mindset of using oil from the region. my GTI is a german car and gets liquimoly, a german oil. my toyota/subaru is Japanese, Idemitsu is a japanese oil (and the oem supplier for Subaru). i have 5w30 in it now.

Honda scooter oil & Castrol, tried and tested ko na. btw yung castrol ang ginagamit ko kapag summer na at sobrang init ng panahon then balik lang ulit sa honda engine oil once tapos na yung mainit na season

I've been running Idemitsu oil in the XT and the wife's Crosstrek for the last four and five years and have been happy with it.

Honda's own 0w20. It would feel sluggish at the end of the oil life. You can feel it on the hybrid model
