About this item

Product details

Castrol® GTX® 10W-30 is a premium conventional motor oil that has been helping to extend engine life for over 50 years.

Sludge is a thick, tar like substance caused by severe driving conditions such as heavy traffic, poor fuel quality, harsh driving conditions and exceeding oil change intervals.
