I drive an early 2008 dpf fitted vehicle so i have no choice but to use this oil.. It is the best oil available for vehicles like mine. Although to do regular oil changes it becomes quite expensive, which is the only negative.

Shop stock for the 10l pack is now ACEA A3 not ACEA C3. 5l pack still C3. If your car requires ultra low sulphur for the DPF (ie Jeep Grand Cherokee WK2), this product has changed. On the Supercheap Auto website (and their computer system) it is still the C3. The specs on the product are now changed to A3, so had to return it and buy the 5l packs.Recommended if it works for you, but be careful that the specs are right for you.
I've been using Castrol oil for many years and have found it to be of high quality.As far as Magnatec DX 5W-40 Diesel is concerned, I have been using it in our diesel Hyundia and diesel BMW for the past 12 years. I have found the oil to be high quality: Oil pressure is constant from when the oil is new to when an oil change is scheduled.It is one of the few oils on the market that is designed to operate with particulate filters: Filters with which our cars are fitted.Recommendation? The highest!
I use this oil in my Landcruiser 100 and change my oil every 5000km. I have done nearly 380,000 km and the car still runs beautifully.
I have used this oil since purchasing this vehicle second hand 3 years ago. It was the oil used by Kia during the warranty period. I change the oil and filter between 7000 to 10000 ks, despite the scheduled service interval being 15000 ks, and find i never have to top up in between changes.
A good oil for my 1.9 diesel, and very good value at 25% discount. A noticeable decrease in time for the oil pressure light to go out.
Great oil. I have run this in my Jeep 3.0 eco-diesel since new. Jeep updated their spec to this 5w-40. Perfect for DPF and EGR vehicles. I change oil and filter every 10,000; and run a catch can.
Been using Magnatec for years in my 8 ton truck with over a million kilometres driven my me , only stands to reason I would use it in my LVD 4x4
