Hello everyone, I apologize for my English, but I'm Italian and I use the translator. I have been looking for a test on this oil for a long time, so difficult to buy (in Europe) and also quite expensive.
Finally 3 tests: Room temperature, 100 degrees and a test that I think is important for rotary engines, regarding the cleanliness of the oil at high temperatures (basically the residues).
I leave you the links where you can find the tests. I hope to do something pleasant for everyone. Please comment.
I also recommend you watch the other tests on this channel (I inform you that I have no connection with this channel, but I find it very interesting) which helped me find a suitable oil for our beloved RX-8.
