Engine oil IDEMITSU or FUCHS

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.

Using it for 5 years, changing oil avery 8000-10000 kikomiters, enjine souns good (as for disel car)

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.

You’ll be fine, idemitsu is a bit of a rotary specialist when it comes to fluids

Fuchs Titan pro 5w50

I think Idemitsu is the better option if you have access to it. Mostly because it was developed for the rotary engine.

Last oil change I've decided to try what my friends run and bought FUCHS GERMANY: TITAN SYN MC 10W-40 and put 2k km on it, I'm pleased, it's nice greasy and cheap

Idemitsu to both, because it’s designed and tested on rotaries.

I have oil analysis done in my TDI and a 10K OCI is a reach. The factory fill was almost depleted of wear additives at 5,500 miles. Fuchs Titan GT-1 was still serviceable at 7,000 miles, but I would not have carried it out beyond that.
