Consistent quality and performance seems to be the norm for all of the Penrite oils. You can feel the quality not just when it is fresh but more importantly when you change over the old oil still has good body and slip to it. I spend a little more on oil and a lot less on repairs. Good value.

Good quality, well-priced and readily available semi-synthetic oil that suits older cars.
always have used this oil with no problems . i have used it in my holden V8's raging from 1970 HQ to 2010 VE SS and the have never missed a bet or purr. would recommend to anyone to use.
Good quality oil what i like is it contains zinc a good lubricant.
I wouldn't use any other oil for my engines, I always have and always will use penrite oil😜
I have three motor vehicles one being a six litre v8 (purchased fourteen years ago) and have been using Penrite Semi Synthetic engine oil exclusively in all vehicles since purchase. I have never had reason to add oil between service on any vehicle and have maintained excellent fuel efficiency with all three.
Been using penrite oils in the various cars ive owned for well over a decade now and have always been pleased with its performance. Cars engine runs smooth and always feels well protected. Best australian brand engine oil in my opinion followed by nulon.
Simply the very best lubricant for high performance tuned air cooled VW engines.
Good quality oil. I’ve been using it in place of the basic SAE mineral oil for some small motors.
