Bought 4 X 5 liters of this oil from Supercheap auto when on sale to test this oil in my vehicle. Previously, both my Nissan Maxima 2004 V6 3.5L and my Honda 2004 2.4L V-Tec both had Mobil One oil and Castrol Edge oil in both vehicles and both vehicles ran smoothly. Vibration was minimal if almost non-existent, tappet noise was completely eliminated, and upon hard acceleration the engine noise was a finesse/jet engine sound. I did reviews on both the Mobil One and Castrol Edge oil. So, at 170,000kms in my Honda and at 230,000kms in my Nissan Ma...Read more

I have recently used 20w-50 semi-synthetis Diesel oil and found it simply cannot maintain its quality over time. I was an engine reconditioner for 20 years and always found that cars regularly serviced with Penrite oils to be extremely clean when I pulled the engines down. This may be due to high detergents in the oil. In terms of my engine, Patrol Z30 diesel, I found initial driving to be good up to almost 5000 but then valve train noises increased and the oil did not maintain its viscosity. It deteriorated to quite thin, has a slight odour a...Read more

I am fairly fussy when it comes to looking after both my wifes and my car and I always try to get the genuine filters,plugs and lubricants recommended for the car or that meet or exceed OEM standards.

I wen't to Autobarn and being a bit tight financially like most of us I wanted an oil that was cheaper than the Mobil 1 but would still be ok,the shop assistant walked over pretty confidently and pointed me in the direction of Penrite oil so I purchased 5 litres.

Worst mistake as now after 4000km it's already thick as anything and cold start...Read more

Been using the HPR 15 15W-50 in my 96 Range Rover, which are known for their high oil consumption and found the HPR 15 reduce this consumption condsiderably. The oil also goes the distance in our extreme climate by not breaking down in viscosity to soon. Engine runs quieter, more economically, & keeps the engine clean free of carbon.

Another reason I chose Penrite for more important reasons are that they're based in Bayswater Melbourne, which means if you have any questions or concerns, they're only a local call away and not an overseas ...Read more

I'm very particular of what product I use in or on my vehicles, and research products thoroughly.
Much of the servicing of my vehicles I do myself, as with friends and family vehicles (which range from new to knackered!)
I've found Penrite does the job without fuss and often exceeds expectations.
Friends that have older worn motors have noticed the difference the oil made in their cars, which comes from people who have little or no mechanical knowledge (the 'turn the key and go' brigade) says a something about the quality of the product.

I have a 2007 Ford Escape with 33000k.Always been serviced well before due time and always had Magnatec.

I have a small offroad caravan which I tow high speed and thought I might get something better to extend the service interval
The Magnatec has been good as the car is used as a daily commute droping the kids at school but after about 8000ks breaks down with towing.

After my mechanic put this oil in the next day the valvetrain noise was noticeable.
A couple of days later on a really cold start upper cylinder ticking was evident and loud.
Used Penrite HPR 10w-50 fully synthetic.
The engine was louder in the cabin and upper cylinder valvetrain noise was evident.
Ford Escape 2.3l have mechanical lifters. ...Read more
