What oil used in V6s
I searched the threads and found little on answering this question. What oil is used by members in their V6's. My default on everything I own is Castrol, but maybe I might want to use something different on this engine.
On all my older flat tappet engines I use an zinc additive, is this also recommended? thanks all, gg

Re: What oil used in V6s
That is a great question! I can't wait to see the responses. I was thinking of trying this because of the "boosted zinc"...
 ...but will wait to see what folks here are already using.

Re: What oil used in V6s
The standard I've heard is Rotella 15w 40. Here's the additive I used, recommended by Jay Leno for old cars with flat tappets. You just put a little in. 1 bottle lasts a few changes.

Re: What oil used in V6s
I have been using this additive for my older cars. I did notice on one of them it quieted the motor and oil pressure was staying higher at idle than before.
