Ester Oil / Mobile1 - Interesting Link

ImportConvert

Spring Mountain is about 45 minutes outside of Vegas.

The Z06 revs to 7K rpm and covers a lot longer stroke, thus the piston is moving faster than in your 370Z.

Yes, it does have a better cooling system, but we still saw 270+*F oil temps. Mobil 1 did fine.

Do you have UOA's to support your claims about the 370Z performing poorly with Mobil 1?

Your oil may be 10-15* cooler with other brands, but what do the wear numbers look like? I agree, if the only difference is temp, use the other brands! I am also not telling you I think you are wrong, I am simply asking for a bit more info.

Have you tried Nissan's Ester oil, how did that do? It has gotten ripped a new one on BITOG and other sites where people post actual data.

^Read that thread. The Nissan Ester stuff is performing VERY poorly when you look at the actual wear data and how the oil is holding up (It's not).

Basically, your "Nissan Ester" stuff is a group III oil with "Ester" in it. Who knows how much? Apparently not a ton of it. It shears easily, the TBN drops like a brick, and it's just not a very good oil, really. The 5-30 DEXOS stuff from Mobil 1 is far superior in every way once you get past the emotional aspect.
