Question:
Ester Oil and Nissan Engines
I've just purchased a Nissan 2009 370Z, which has a 3.7 liter engine that produces 332 HP @ 7500 RPM's, and has a compression ratio of 11 to 1. I've been advised by the Service Manager at Cronic Nissan to run Ester Oil in the engine rather than a good grade of oil, like a 5W-30W. He said that Nissan recommends it. Well, I've researched everything I can find regarding the use of Ester Oil in my Nissan 2009 370Z, and I've been unable to find anything that alludes to the use of Ester Oil in the 370Z engine! What's up with the Ester Oil thing? The only use for Ester Oil that I'm familiar with is for air conditioner compressors and other types of compressors!

Answer:
We have not been able to get much information on the Nissan Ester Oil but our analysis indicates that it is part or full synthetic oil. Many synthetic oils, including Mobil 1, contain a variety of synthetic fluids, and usually this includes esters. We would recommend Mobil 1 5W-30 or Mobil 1 Extended Performance 5W-30 for these applications.
