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.

Castrol MAGNATEC Engine Oil -10W-40, 5 Litre is a Quality and consistent product that I can always rely on to keep my car running efficiently at all times.My only significant concern is there is no tangible record in my account and or on my paper purchase receipt stating that my competition entry has been successful. This issue also occurs regarding my emailed receipt which if in place would give entrants peace of mind.

Castrol MAGNATEC Engine Oil 10W-40 5 Litre
9 November 2020

I've been using Castrol products for about twenty years and at that time the Magnatec range of products was relatively new to Castrol's portfolio… at least in Australia. Since then I believe the Magnatec range of products has been a very successful product line for Castrol.This particular Magnatec product is a high quality 10W-40 part-synthetic engine oil I have personally used many times without issue or concern. It meets the latest API SN/CF and ACEA A3/B4 specifications making it especially suited to many Toyota (i.e. Corolla, Camry) petrol vehicles and some light duty diesels without a diesel particulate filter (DPF).A very similar formulation known as Magnatec Professional Series (though only available to their trade customers in bulk containers) is used by ... MoreI've been using Castrol products for about twenty years and at that time the Magnatec range of products was relatively new to Castrol's portfolio… at least in Australia.

Castrol Magnatec, Best Oil Ever Made
12 May 2021

I have used this Oil since it was made. And over the last 10 years I have used it in a Holden V8 and a XR8, and the motors love it! The best thing about Magnatec is it stops all Start up noise. It keeps the oil all over the motor when the motors cold, that’s the benefit Magnatec does for protection with start up and acceleration. And I haven’t had to top up the oil either as said in earlier review. (This is only my opinion so if you have an engine with problems it won’t fix it! But it will protect it!) Best oil ever made!

Magnatec oil is the best.
13 May 2024

I've used Magnatec oil for the last ten years, I've always been impressed with the way the oil holds on to all the metal parts no matter how long it has been since it was last started. Using the dip stick to check the oil level, you always have to wipe the stick first and redipe it because the stick is covered with oil which proves how the oil sticks to the metal.

[Rewarded Review] Great and quality oil brand
8 January 2024

Castrol is a good brand we can trust. I am using Castrol from long time. It never gave me any engine troubles. Prices also reasonable and it was a great bargain with my last purchase with a big discount!
