Hi Mark, Best to contact our Tech Team on 1300 736 748 or email tech@penriteoil.com.au



I have a 1964 Austin Healey 3000 and I was recommended to use HPR 50 40-70 as it would reduce oil consumption.
I previously used Penrite HPR 20w60. On a recent trip of some 8000 miles my motor used around 7 litres of oil which I considered excessive.
What is your recommendation?

Hi David,

Can you please contact the Penrite Techincal Team on 1300 736 748 so we can discuss directly.



I am going to put HPR 50 in my 4 litre falcon motor. (10-30 is recommended) will it gum up my lifters and provide start up wear due to it's high viscosity? I have used 50 in a 125 motor cycle and it worked ok. I do not want gummed up lifters in my 4l falcon. 24 valve

Hi Wasa, This is way too heavy for a Falcon engine. You would be better off using HPR10 if it is burning oil. (Link to HPR 10: https://www.penriteoil.com.au/applications/car-4wd/engine-oils/hpr-10-10w-50-full-synthetic). If you have any other Technical questions please call 1300 736 748 or email: tech@penriteoil.com.au
