Well Your putting very high level oil in. I dint car about gas because this is my weekend car. But what was API spec for your car? G37 and 370z is 5w30. That's for gas savings. Did you have a v8 ? Also this oil is not for every car out there. It's japan base oil and some oils do better in other cars. And most people out there will never use a 0w 50 oil. This oil dose very good in our cars. Also do to the VVLE I wanted a very good oil that was API approved.
