Everyone with oil temp issues

smartbomb

I run motul 300V on all of my high performance street and race cars. It is an ester based oil. I have had good luck with it. My race engines go about two seasons between teardowns which is pretty unheard of.

For the wife's car and our regular stock cars I run Mobile one.

For the 370Z I would run light oil for regular street driving but 15w50 for track use or spirited driving. Its sort of a trade off, the additives that make for a wide viscosity range also tend to cause sludging and break down sooner.

I think a Z needs 3000 mile service intervals.

Its interesting the 330 turbo BMW's had no cooler when they were launched but had to add one when customers started to experience high oil temps.
