Been sticking to castrol magnatec full synthetic oils for few years now. Found it to help with engine performance without any problems to engine so far on a ute that does 200+ kms a day. Used nulon full synthetic which seems to make engine more sluggish. Used shell and penrite, ok but average performance and protection(assumption)

Potentially the best value for money engine oil when on special. Not only is it suitable for Ford turbo engines but being acea A5 it's suitable for long drain and offers excellent fuel economy. Id say it's better than Castrol edge.

I’ve used this oil in my Ford Ranger for years and it seems to be a great product, after 10,000k’s oil is still pretty clean and my oil change intervals are 12,000ks.Expensive, but when on sale price is competitive.

Castrol MAGNATEC Stop-Start Engine Oil 5W-30 10 Litre.It's much more convenient with a 10 Litre container, less worry about having to run short because of not enough, it's better to have more Oil than what needed, some newer Engines need more Oil, and I like the Castrol Brand, I've been using it for more than Fourty years and it's never let me down because it doesn't go sludgy like other cheaper Oils.
Magnatec has been around forever and earned a good name. Fully synthetic oils of today are so good. This oil met the spec my car required and it was on sale. What a steal!
Castrol Magnatec improves fuel efficiency and makes a car run smooth and overall cooler in th extrreme tempretures we have. The friendly team at Supercheap Bunbury had my order ready and followed up to ensure we pick it up for the weekend.
I've been using 10W40 Magnatec for years in my VX V6 and very happy. Just done 200K so upgraded to this new oil. Engine seems to rev a little smoother and is quieter.
Great price on sale.Click and collect so easy.Castrol, so know it is good, but disappointed to find it is manufactured in Thailand. Knowing this I would prefer Penrite, but it was not on sale.
I had to mode the PCV VALVE on.my alloytec motor on my 2005 caprice. This fully synthetic oil has done an excellent job of removing the sludge that built up before the mod, due to the quality detergents within it also the motor is running very smoothly due to its high viscosity
Staff were very quick to help me. I didn't know where to find the oil. I had a photo of the oil that the car dealership mechanic had told us to buy. Staff were amazing in helping me. I had a very enjoyable visit at Noosaville store.
