Engine oil IDEMITSU or OEM Audi

Audi TTS from 2016 and depending on wether im driving comfortable to work in winter it can be 95-98c, pushing it hard in summer it goes up to 107-108c at times.

My S3 seems to be at 222F all summer when commuting, I think it gets near 240F after a good autocross run

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

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

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

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 don’t drive my car enough to hit any of the reasonable mileage points. I change my oil yearly, roughly around the time it gets inspected. Might be overkill (last year the car moved 2k miles, the year before was 2.4k), but I figure the $80-85 I pay is worth it. My wife’s Q7 will be getting its oil changed every 5k miles. It’s a 3.0T supercharged and they love to eat oil, I’d probably add half the oil back just to make it to 10k.

I just change it every 3k as a maintenance think no one told me to. I'm just afraid of messing up my turbo if I waited to long.
