I was talking to a non Porsche engine building /machine shop yesterday and he told me new oil formulation regulations means we need to add zinc additive in older cars
Any one out there have knowledge ( versus opinion) on this. I use Brad Penn but he seemed to indicate this is industry wide. He was not trying to sell me anything |

The pro who rebuilt my engine filled it with Shell Rotella. Seems to be fine so far.

The pro who rebuilt my engine filled it with Shell Rotella. Seems to be fine so far. We use rotella t. Cheap enough and has the right stuff in it. Which Shell Rotella do you use? Jeff B I would assume Mark's shop uses the original dino (pic below). I've also used T6 and like it, but it's synthetic, so never use it on a new engine till break in is complete and synthetics have been known to make leaks in aircooleds worse.
