Engine oil IDEMITSU or OEM Audi

I’ve done both and extractor takes out like 97% of oil. I still had about a half cup when I pulled the plug.

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.

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 had the same issue on my 2019 A6 3.0 last year. Two times I had to pop into the dealership to have oil removed (no charge) and the issue was due to dilution and short trips.

On my 1.8ts I usually change it when the motor blows up and has to be replaced. They used to last perpetually but builds have progressed to the "Yes it absolutely is going to grenade or window the block before 10k miles???? so really I only ever have to FILL oil 1 time???? I wish this was less true than it actually is. On the rest, (2.7tt and 4.2) 10k miles if you use good full synthetic oil and a nice filter

Why do Audi’s burn through so much oil? One thing I don’t miss about my 2019 Q7 is the constant adding quarters of oil throughout the year.
