Engine oil IDEMITSU or OEM Volkswagen

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.

This one was done at the local VW dealership where they added 6L of VW oil and were nice enough to collect a sample of the oil for me to send off to Blackstone. The oil in this sample had higher quantities of wear metals present vs the 3rd sample, but that is to be expected as there were more than twice as many miles on the oil.

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 had a 2009 Jetta diesel that used a bit of oil until it hit 60000 miles, then it stopped and did not use ANY between the 8000 mile intervals I used.

Varies too widely, my trans am takes conventional oil and inexpensive filter and is an easy job, while a Porsche 911 requires removal of the oil pan and expensive oil, while my emission cheating Jetta only can use $10/qt special oil. Can be from $40-400.

My previous MK7 GTI used a quart about every 3K miles from the day it was new until I traded it at 212K.

This is not fine. VW oils like 502, 504, 508 and 511 are not typical oils. They have a different additive package and the viscosity is different, like the extended performance 5w30 is not the same viscosity as a 504 5w30. The 504 is thicker and is closer to a 40w.
