The rest of the world knows how good this product is. I love the Australian oil brands and use them when I can. However, they don't compare to this oil. Its the only oil which goes in my xr6 turbo. Its oil that makes a difference, no blow by or excess consumption. A true long life oil. Check out the viscosity index on this oil its better than most of the 'true synthetic oils' i.e. the really expensive ones.

Switched from penrite full synthetic 5w40. Picked up on special from autobarn $39 for 5 liters. The idle revs on the Liberty had dropped after around 2000kms on penrite but since the Valvoline oil change they are back up to normal indicating much better oil pressure. Will buy again when on special.

Fast flow engine oil and protect the car from cold start during the cold weather and even in hot summer.
This product has excellent cleaning detregent and this product can stay long as last.
I was tried this product in many cars and all work perfectly.
Rating 10/10
Thanks for valvoline.

Bought 4xbottles of 5 litres from supercheap auto during sale. Used oil in both Honda Accord Euro 2.4 litre VTech 2004 Luxury model n Toyota Kluger V6 Grande 2013 AWD. Both engine responded extremely smoothly with the engine oil. Extremely little friction so both vehicles was able to achieve and maintain Motorway Speed n upon hard acceleration with little effort on the pedal. Speed can be maintained longer before requiring gas to be tapped.
