Always my go to oil when I can afford it. I had a small oil leak and this brand would last longer but it usually cost more so I can't always get it although maybe I should have paid the extra so my van would have lasted longer.

This is a good deal and great oil. It comes in handy when you have an older car that has tank problems and goes through a lot of oil. The bottle is easy to pour from. My old car runs great when I use this oil.

This is a great oil to use on cars with high mileage. I have tried other brands of oil but have switch back because it doesn't work as well as Castro oil works. I would highly recommend this for older vehicles.

I've been using this product for over years in about 5 different vehicles that I've personally owned. It has worked very good and rates highest in it's class.

We use this for our 2006 Honda CRV with over 222000 miles on it. Works great for us and has kept our car running like a top!

This is the only type of oil that I will use in my car. It's high quality and makes my car run smoother

I've us d Castrol oil on my vehicles for years. It holds up well with all the miles I put on my SUV.

I have a slow oil leak on a 2003 Accord. This oil is great for engine performance and seemed to help seal some of the leaks.

Other oils seems to not work in my car as well. This one is great! My car even stopped making as much noise. Seems to last longer as well.

I have used Castrol oils for years in all of my engines with no problems. All of their oils are good.
