I have been using this oil now for many years and have never had a problem.I see no need to change now.

The recent label change from Castrol made it difficult to purchase the same oil I still had left over from My last change. But the staff member was very helpful with the confusion.

I have used Castrol Diesel oil in Landcruisers for many years and have found it seems to hold its viscosity exceptionally well, I have rarely had to top up between services and never had any oil related issues. Magnatec also offers minimal wear from cold starts due to its adhesion ability.I think it’s good value for money.
Best oil ever for my old lc100 turbo diesel I can hear it purr after the oil change
Great product always at a good price at some stage at Supercheap. The vehicle runs beautifully on it.
Good oil, right oil for the car. Good price. Would recommend for deisel cars.
Confident from long term use that this oil works well with Toyota 78 series (2002). The vehicle has spent many years in the outback of NT and has endured extreme temperatures and terrain. The oil is changed every 6000km and after 300 000km still does not use oil. I regularly add an oil additive to help hold its’ viscosity.
I’ve used Castrol oils in my cars, motorcycles and lawn mowers for nearly 50 years and have never been disappointed with the engine protection they offer. This one’s no different. With just over 200k on our 2013 Prado it keeps the engine clean and in excellent condition and still returning excellent fuel economy.
never had any issues. all our car engines have run without fault. great oil for engines even though the write ups are not agreeing or reliable id say. We shall leave on a good note Hi ghly recommended
