<VV> Rotella Ask Our Expert: Gasoline Engines

[J R Read_HML]

How Timely...

I've been doing some of the same searches this evening.  Want to do an oil 
change in the AM and picked up a gallon of Rotella T (Triple Protection) 
earlier.  I have been using Mobil 1 for diesels, but it was not on the shelf 
at Auto Zone.

This is a multi-weight oil - 15W40.  Now that I read the Rotella label more 
closely, I'm seeing "Meets API Service CJ-4, CI-4 PLUS, CH-4, CG-4, CF-4, 
CF/SM".  I'm thinking that this should NOT go in a Corvair engine.

Agreed?

I think I will return this tomorrow and go find the Mobil 1 diesel 
elsewhere.

If someone thinks I'm on the wrong track, please let me know.

Thanks.

Later, JR
