Here is my 2017 civic 1.5T 6MT with the duration of this OCI being run on an aggressive custom tune. No ill effects from running the 0/40 at all that I can see. Could have gone much further on this oil.
Very little oil collected in my mishimoto catch can which is the only other mod. I was still achieving 45 MPG on long trips and smooth power when I need it. I love this motor. Also the previous test was done on M1 0/w30 AFE.
