To add to this..

The last 3 oil changes, I've used Motul oil and had no dramas. It is a little more expensive, but I find start up she's a little quieter, in comparison to when I used other oils.

My choices are Penrite or Motul.. I dont flog the life out of my car, although she does get a spanking once in a while.

My mechanic looked at her last month and commented on how clean & healthy the motor looked, however he said he could only see so much as he didnt pull the motor apart, only did a few gaskets.

I actually brought this question up yesterday at work and a few of the other assessors here and also customers constantly brought up Penrite & TRW, saying that they swear by them and wouldnt use anything else. Im talking about customers with 61 Chevy Impalas, 83 Porsche 911, Lotus Exige, Buick Ninety Eight, Lincoln Continental, VE Commodores, VL Calais Turbo etc.

So different cars, different people - Two brands that constantly came up when talking to them
