Changing to mineral oil

[rev 01]

Just switched to Penrite mineral & agree with previous post from Col in that my clutch is operating with noticeable improvement.

I think there is a question mark over engine longevity with the synthetics as my car has been run on fish oil for 156,000 (Mazda) & has cam box rattles like a tappety old FJ Holden despite being serviced on time with no exceptions. <i></i>
