Engine oil ZIC or IDEMITSU

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.

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.

Been using it for several years already and very popular brand na sya ngayon since anak ni Lucio Tan ang distributor.

Use their X7 if you plan to change oil every 6 months. Use X7000 for yearly changes.

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

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

Used zic for several years with no issues. This year lang ako nagpalit ng ibang brand since nagmahal na zic dun sa suking auto supply ko.

I’ve been using zic oil for 6 years now. Ok naman I did not experience any issue.

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