Delivery Fees

Your delivery cost will vary depending on the size, weight and location of the products you choose to purchase as well as your delivery location of choice. Normally the larger the item, the more expensive delivery will be. Extremely large goods (ie. Items requiring a two man lift) will also incur higher delivery rates.

Please note: As we use couriers to deliver all parcels, products cannot be delivered to an unattended address. The courier will require a signature from an occupant at the specified delivery address at the time of delivery, if no one is available to sign for any parcel a card will be left and the parcel re-directed to the nearest Courier depot. You will then be responsible for collecting the parcel from that depot or paying an additional charge for re-delivery.

Supercheap Auto recommends all deliveries be shipped to a location that is attended during business hours, whether that is a home, work or other address, to minimize any redelivery delays and/or fees.

You may incur additional delivery fees/freight charges within the checkout (in excess of the fees and charges specified above) for:

  • Large quantity or bulk orders.
  • Express or urgent deliveries; or
  • Non-stock and/or bespoke items

Bulky Items

At checkout, you will be notified of shipping costs for your approval, these are calculated automatically by the site in accordance with our courier companies' freight charges via a courier aggregation application (supplied by Temando). Bulky items are those with either a high weight or large cubic volume. Products are allocated as bulky as determined by the shipping methods of our courier companies.

Please note if your cart contains non-bulky and bulky items your cart will be calculated accordingly.

Delivery Time Frames

We use a selection of courier services with delivery times of between 1 - 10 business days after dispatch for smaller items, and 3 - 10 business days for larger items, depending on your delivery location. Courier deliveries are made during business hours, Monday to Friday only.

We are unable to deliver goods to PO Box addresses as all delivery orders are sent via courier services. Unfortunately we do not currently offer Authority to Leave (ATL).

International Shipping

Unfortunately Supercheap Auto is currently unable to provide international shipping.

Reasons for order delays

  • Entry of an incorrect or incomplete address during checkout.
  • The address had no-one to sign for the parcel.
  • Incorrect payment information was entered against the order. Please double check all details at time of checkout as your order will only be created upon receipt of payment.
  • In the event an order is flagged for verification we may need to get in contact via phone before dispatching some orders. Personal details may need to be confirmed for fraud prevention if we are unable to verify the shipping destination to protect the card holder, and this may delay shipping.
  • Occasionally if a particular product is in high demand we may need to supply product from outside of our standard delivery network. This can cause delays in dispatch if orders are directed to regional locations etc.

If your order is not received within the quoted delivery period please check your order progress via our Track & Trace portal, alternatively contact our Customer Support Team on 1300 175 010 or complete our online enquiry form. We will generally respond to online enquiries within 24 hours.

I've used this oil at several services on a couple of different vehicles and it seems to be as good as any other mid priced oil. Great buy when on sale.
Castrol Magnatec Engine oil 10W-40
The 10W-40 Magnatec oil is great for the Aussie climate, thin enough for good economy but can still handle the higher temperatures in summer. Being a semi synthetic oil it's cheaper than the fully synthetic oils but offers similar properties. If you buy it when it's on sale it's a real bargain and your engine will love you for it!!!
Good quality oil.
Best non-fully-synthetic oil
Good engine oil
Castrol Magnatec Engine Oil -10W-40, 5 Litre - 5

Been running it for the last 5 services!

Castrol oil

Castrol Magnatec Engine Oil for Petrol Engines
This is a great oil I use it all the time in both my petrol commodore and my diesel vehicle. It keeps the engines running very clean and they actually do run quieter. Castrol have nailed the right oil here for noticeably cooler running and increased fuel consumption and performance by an engine oil. Others are good as well but I personally will not use any other engine oil in my vehicles AAAAAA++++++
Only for use in older cars
Great when on sale for older cars , however the oil is Semi-Synthetic which in simple terms it is thicker and does not flow as fast through your engine/oil pump compared to a fully synthetic oil. Nothing entirely wrong with the oil it does the job but i would not recommend this oil for modern cars (Year 2000 onwards) that are serviced regularly (every 5000/10,000km). i would only recommend this oil if you have MINOR oil leaks or Minor Oil Consumption, DO NOT use for extended oil drain interval (15,000km+) as this is also not stipulated on the bottle from the manufacturer. A semi synthetic oil is not as high quality as a fully synthetic oil and over time it will lead to alot of sludge buildup in your engine especially Castrol Magnetec because the tiny metal particles it supposedly collects in order to protect your engine have to eventually subside somewhere , just remember you get what you pay for.
toyota oil
Have used this oil for years and find if you use this oil it protects your car
Love the stuff
Love the stuff and the price
oil aint oils
Castrol Magnatec oil is top of the shelf.
Magnatec Good Oil
Due to bad piston slap in my 2001 Holden SS that Holden mechanics cant hear and the fact it uses 5 lt of any other brand of oil in 5000km, Magnatec is the only oil I can run in it. I use it in all my cars though and it's great.
Lovely drop. Best served chilled.
A mazda customer
I have been using this oil on my 2006 mazda for over a year and it is perfect. It is value for money.
Great Oil
Heard this is the stuff for my old ute
Excellent product
It's an excellent product and I bought it with a great discount
Great oil and a great price.
Use Castrol Magnatec regularly and purchased my next lot of oil early as SuperCheap had a great special offer.
Excellent product for many years
Service is very good.
The item was wonderful.
Castrol Magnatec
Use this oil in my Toyota Corolla Accent never used anything else, purchased car second hand with 140000km on the clock. Car now has 400000 and still going strong thanks to this oil.
"Castrol Magnatec" is the brand I choose to protect my investment. It keeps the engine clean and sludge free and when used for everyday applications, it minimizes wear and tear on critical components such as cam lobes/valve lifters, big end bearings, main journal bearings, cylinder walls and piston rings. I highly recommend this product for the average day-to-commuter. Worth every cent! And at Super Cheap that often means paying far less than the competition!
Good Oil
Very happy with this oil have used it for years.
have used this stuff for ages...I like the fact that it clings to moving there is no friction on start up......that is where most engine wear you cant go wrong with this stuff....Especially when its on special.
Castrol magnetic
Excellent priduct
Value for money
As always this oil is great value for money and great quality too. It's easy to pour handle holes and volume viewing strip makes handling the product very easy.
Castrol Magnatec Engine Oil -10W-40, 5 Litre - 5 Litre,
Great pick up when on special. Good oil for a petrol Landcruiser.
Good price good item
It's good price for good item
Magnatec's Great
Been using this ever since it first became available. Prior to that used an American additive that did the same thing. I really like the technology and realizing that the biggest wear occurs from cold, this is the best way to make sure the oil is still where it is needed. Super thin oils still take time to pump around the engine, but magnatec sticks to the right bits. and is there at the first revolution.
fast service and cheap
Castrol Magnatec Engine Oil -10W-40, 5 Litre - 5 Litre,
Only oil I use, and at this price will continue to buy it.

One of my favourite oils
Castrol Magnatec is one of my favourite engine oils It's offering maximum protection for engine from the very start This 5L package represents a good value for your money
No problem
Used in all the cars I have owned, never a problem
Mr Wai Kam
A great product at very competitive price only applicable to members. I will continue to support Supercheap for their products for many years to come. Merry Christmas and Happy New Year to all the people working for the company. Best Wishes William Tang
Top quality oil at a reasonable price
Funny how Gmh states that only 100% synthetic oils be used in the VE, when their dealerships use semi synthetic oil to keep the service costs down as that most Australians don't expect to have to pay over $140 in oil and that now Holdens Fixed Price service has become the norm, 75%+ of dealers are using Castrol Magnatec semi syn as their chosen oil. Don't believe me? Easy to get on the phone and ring a few dealerships
no complain
Store short changed me
I sent a staff member to collect and they gave me 1 instead of 2. Don't bother with click and collect......waste of time
it is super cheap!
Unbelievable price and service.

Castrol Magnatec Engine Oil -10W-40, 5 Litre - 5 Litre, 10W-40
Cost effective product for moderate aged cars (2004 multi point injection 4 valve engine)
Magnatec Oil
Low score on features because there are no real features of a bottle of oil to even think about. The purchase was easy and convenient. Could not go on the day it was on sale, but picking it up a couple of days later from the local store works great for me. Thanks
Castrol Magnatec Engine Oil -10W-40, 5 Litre - 5 Litre,

Excellent value and services,very happy.
Castrol Magnatec 10W-40 Engine Oil
I have been using this oil exclusively since it became available many years ago. I have achieved great engine life in a number of vehicles, it keeps the engine clean and free of any sludge.
Always my preferred oil
I have my 1999 model Subaru Forester serviced regularly by my trusted mechanic but always supply this oil as it always seems to run much more quiet on start up compared to other oils. It was also recommended to me by a long time friend and mechanic in another state as being the most suitable for my car. I have used it since I bought the car new. I still own the car because its still 100% reliable and in perfect running order. I always wait until its on special and grab 1 or 2 bottles from Supercheap Auto and hold them until needed rather than paying full price. I always order online as I am disabled and cannot always get to the store during the sale period and then either collect them myself or have someone do it for me. Its a good reliable product and the online purchase and click and collect is my favourite mode of buying from Supercheap. Its a win win for both of us!
Castrol the name synonymous with top class lubricating oil . As a young lad in the fifties i used Castrol and i still use it now.
Don't believe the hype
I Started using this after previously using Valvoline for 20 years... I'm going back to Valvoline. The car doesn't rev as nicely with this oil, there is varnishing evident, and oil consumption has increased. Never again.
An ok product, probably over priced due to the name. The BP equivalent was also OK at 20% less (normal pricing). Not saying one is better or worse, they both work and these days nearly any oil will achieve 3 to 500 thousand K's and by then no one really cares which oil was used.
Grab it when its on special
Great oil, but buy it when its on special otherwise its too damn expensive.
Oil is oil and this is might fine oil..
Trusted magnatec does what it needs to do
Excellent Product & Great Service
I have used this product for many years now and would never change to another brand. I've never had any problems with this product. The service I received was also the best experience I've had in Supercheap Auto in the many years I've been shopping with them. Kingaroy store has the best customer service staff out of all the stores I've been to. Although, spare parts team could have more staff at the ready, but the front counter staff are perfect! Thanks guys & gals.
really works
this product is suitable for old small car, really good for speed up and lubricated
Great oil
Great oil
great product!
Good quality
This kind of engine oil has a good quality , I advise to use it ,I use it for my Toyota Corolla . Thanks .
Reduces valve lifter noise
This is the only oil which reduces valve lifter noise in the generation 2 (93-2000) Pajeros (petrol engine) we have owned. Other oils, including those recommended by Mitsubishi, did not work well with this series of engines.
Awesome Product
I've used Magnatec in both my 100 series cruiser & my 05 Prado, the difference is quite remarkable. Engine noise is down in both vehicles & the difference in driving the Prado was unbelievable. Its the only oil I'm using from now on.
Proven Product
I have been using this for over 220,000km in my 1995 Holden VS 6cyl and traveled across Australia. I change my filter and oil every 5,000km (oil is cheeper than motors) and I still get around 9Lt of fule per 100km. My motor shows no sign of leaking, (have a slight wet spot at the rear seal but this was a fault from manufacture) and she still purrs. Like JLVPrime, I think it could be a little cheeper. I have noticed some others have it a lot cheeper from time to time. Sorry CLUB +
Very good protection
Many years ago I choose this oil for my dads 1986 Mazda 323, since he was a kind of person to start the car and just drive without warming it up first. This oil has performed really well during start ups and drive with out warming up the car. To this day the car has been hardly used but it is still in good condition thanks to this oil. This oil was cheaper many years ago but now prices have gone up a lot for this oil, I can understand why the price is what it is nowadays but I still prefer if prices where like back than for this oil.
Great Buy
Recently serviced a friends Mazda 6 with Magnatec. Can report that the engine feels smoother and runs quieter since. Much cheaper than going through a dealer!
I had my Holden V6 Sportwagon serviced today at my Holden dealer. They charged me $83.53 for 6.5L of this oil, plus they also charged me $15 for "oil conditioner" whatever that is. Take a look at the Supercheap Auto price for Magnatec. Holden dealer pricing on oil is outrageous!!
Great oil, wish oil was cheaper
Castrol make great oil and a handy bottle. Just wish it were cheaper!
Magnatec 10w-40
i Have been using this for thousands ov ks in my lexus and every oil change with it, you notice the performance diference!
