Castrol GTX 5W-20 Synthetic Blend Motor Oil, 5 Quarts

I have been using this product since it's been available. BMWs (mine) runs hard, never had a problem.

Great product

Just changed the oil in my car using this product, and it's working great.It's definitely worth the investment, and the price is a good value too.Overall, it's a solid choice for anyone looking for quality oil.

Hard to find in stores and when you do it's way more expensive. This is a synthetic blend and I use this with 16 oz. of Marvel Mystery Oil every oil and filter change. Price is great, Shipping on the money. Best bang for the buck. And yes. I do have 335,000 miles on the 2006 Chevy. My 1986 S 10 had 354,000. The body rotted from the salted street after 19 years, but the motor was a strong as the day I bought it.

Price isn’t competitive.

👍👍

its motor oil. The selling point is its about the same price as the auto supply stores. I live out in "the sticks" so being brought to the house and saving drive time and fuel makes it a fair deal.

Castrol oils are recommended by name among several of the car makes that I've owned. Probably they have great marketing people, but also the products hold up well in third-party testing. I like to buy the newer "bag in box" packaging, by the way. Very easy to use.
