Engine oil MOTUL or IDEMITSU

I pay about that. Quality oil and filters cost money. Many shops price oil changes as a loss leader. Euro oil changes are not sold this way, you pay the true price of the service (roughly $80 in supplies, half an hour of labor). I pay ~$160, But you get quality oil in return.

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 made myself the services, and used Motul 7100 10w50, I can feel the gearbox it's smoother.

Here is what IAG recommends

FA2ODIT (91 or 930ct) - Motul 5w30 8100 X-clean EFE, change oil every 2500-3000 miles

Motul 5w-40 8100 X-clean Gen2 may be used in climates where the average ambient temperature is above 80° fahrenheit. It is important to note that the oil used must carry the GM dexos 2 rating.

Motul. Always. Held up over 500hp for 2 years zero issues on unopened stock block plus its what almost all tuners recommend.

Motul 8100X-Clean for me, no problems!

I’ve been runnin Motul 7100 full syntetic for the last 15.000 km’s (9300 miles) never had an issue once.

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.

The red Motul is amazing stuff!

I used Motul with ester. 15W-50 I think? It was for a 16’ Continental GT. Seemed to work fine.
