I don't usually write reviews but I wanted to share with my fellow Z guys especially seeing a lot of people with oil consumption issues.
My oil was changed at 1000 miles with the Nissan Ester oil and at 3000 miles I changed again to Amsoil signature series. When the oilwas drained ihad a little over 4 quarts.
Oil changed at 6500 miles (3500 miles driven hard) and exactly 5 quarts back into the bottles. So there was zero oil lost. Stock oil cooler and 90+ degrees here in the South.
My 350z was the same with no loss of oil. Also their gear oil made the transmission 100x smoother.
Hope this helps some of you if you notice the Z losing oil.
I'm not paid by amsoil, just a long time customer
