Engine oil IDEMITSU or ROWE

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

Rowe 5W40, every 10K or 1 year

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.

I found out that most of it came from the valve lifters. So I began using Rowe 10W40 engine oil. That helped a lot.

Got these Rowe bottles. Fully Synthetic. German. Lets see how it performs.
