A good product

Castrol is a great oil, and buying online through Walmart is a big help at a time when off-the-shelf purchasing can easily be twice the cost at even cheaper automotive stores.

Excellent product and quantity for price

Love the great quality of this oil for our 02 toyota camry--it sure beats stopping at every gas station for a $4-5/qt of some off brand low grade oil.

Castrol provides good quality for our vehicle care, the larger size eliminates a bunch of small containers to be recycled. We are a long term happy customers.
