Has anyone tried the product in there car and if so, with what result?

 

I used it in my previous Porsche (90 Targa), but don't in my 02 Targa. My mechanic tells me Mobile 1 is the best to use. Of course tht could be personal preference, but I've heard the same from others.

 

I used it many years ago, never in any of my Porsches... Never noticed anything different...I think with your 03 and Vette I'dagree with cmilam anduse Mobil 1... With the older Porsches I'd use a Brad Penn oil... just my $.02

 

Thanks guy's you both are most likly right
