It's Penrite for life unless they plunge in quality one day.
I could notice the smoother running of Penrite Vantage 15w 40 premium mineral over Shell Helix.

I grabbed a good deal at Repco recently with a 6 litre bottle for around $28 and three one litres for $5.90 each. That was to change the oil on the Laser and the Fairlane with about a litre left over for top ups.

Amazing how dirty the oil looked after 6 months and 3000km in the Laser when the intervals are 7500km.
I would never let it go much beyond 5000 ever since I got it 10 years ago. It looked too dark on the dip stick by then.


Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
