It is suitable for use in high speed 4-stroke diesel engines that use a broad range of fuel qualities. It is compatible with diesel engines fitted with EGR and the latest exhaust after treatment systems such as; DPF, DOC and/or SCR. Recommended for use in all naturally aspirated and turbocharged diesel engines fitted in trucks, tractors, buses, LCV’s and off-highway equipment, agricultural and fixed plant machinery. One of the main causes of damage in modern engines is abrasive wear. Castrol RX Super 15W-40 CJ-4/E9 with DuraShield Boosters is proven in industry testing to provide protection to your engine in two ways: Under severe engine operating conditions soot can agglomerate to form large particles which displace oil on moving metal surfaces and results in metal to metal contact. DuraShieldTM Boosters helps to prevent the agglomeration of soot as well as protecting surfaces from wear. Provides a protective layer on the moving metal surfaces which resists break down even under difficult conditions.

Always use castrol in my LN106. Afterpay available on their website makes doing services easy and affordable. Castrol oil at Autobarn is always cheaper than other well known autostores. Also bought an oilfilter to go with and autobarn always stock and cater parts for older vehicles like mine. One stop shop always when i go here.

The 5t litre containers of Castrol RX super were better buy, 7 litre too big quantity. Also don’t think much of plastic seal on inside cap, when u open seal bits plastic can drop in oil then motor which not good for engine, especially if pouring oil from container into motor, piece plastic drops into motor, imagine damage if didn’t know that happened, used extensively super for years but no more. Very bad design of cap, what wrong with 5 litre with plastic cap seal
I have used Castrol RX Super 15W-40 in my Toyota. It has 300,0000 klm on the odometer. I have always specified this oil at every service
I have used this product for 27 years of owning my Daihatsu tipper and is original engine without a rebuild. Oils just ain’t oils.
Worked fantastic to cook my Chicken Schnitzels.. a little bit thicker than what I am used to using but all in all a nice even cook
Great oil but the price in not justified especially since this is just a good quality mineral oil not a synthetic oil. Does a good job for the old sooty engine but will not last past 6000kms if you not a common rail engine so a bit expensive.
Its Diesel Engine Oil as recommended by Cummins Australia
A high quality product at a competitive price and commendable service from staff.
