While not using an ester based oil does not damage you car it just gives off the sound of your valvetrain so Ester just quiets it, thats all it does???. From what I was told by the service manager who is very knowledgeable about the Nissan oil so knowledgeble hes a service manager not a engineer, he stated that the Nissan oil is infact did he state it or is it fact? purchased from Mobil1 but they add ester to it and also put their name on the white bottles proof?. Hope this helps you out.

The owners manual recommends ester oil over regular synthetic. Its oil, how do you think it helps quiet the valve-train, by putting ear-muffs on it? No, by doing a better job than conventional oil's.

You wont hurt your car by using regular synthetics but the higher tier formulas like Redline are what is recommended. Why would you use something else... To save $15.00. That's the same line of thinking on why I only use 87 or 89 octane when the manual says 91 or higher... Saving $2.85 a fill up to spend on that dollar menu. Buy a Prius if you want to play that game, if you buy a sports car then treat it as such!
