I have used mostly Castrol for over 40 years and have always liked their products. The engine was immediately quieter, although it was replacing Castrol.

Good engine oil, always use this brand ever since.
As always the benchmark of oil. Always reliable, even when I do large 3000km trips regionally. Great stuff.
I was looking for a good oil to use for our Transit Camper Van, before undertaking a trip around Australia in September this year. The specs of the oil ticked all the boxes recommended by the manufacture , plus some. Completed 19500 kms trip without a hitch in 63 days. Covered a lot of hostile country with temperature extremes. Happy with this product, changed filter and oil, ready to go again.s
Always my go to. Good for 10,000km every time. I suggest trying this because it goes the distance.
In cold weather (which we had in Summer as well) heavy weight oils 20w-50, 15w-40 are hard to reach the lifters hence resulting in tapping noise, harming the engine components.Put this as a top up or 1/4 mix with thick engine oil at oil change the noisy lifters become quiteEspecially for older cars.
Great product! Best oil going for my Ford mondeo diesel! Will always buy this oil couldn't couldn't happier
Going to 40W makes it good for motors needing fully synthetic oil thats a little thicker when hot . As in hot weather . Long trips and fully run in motors .
