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.

Works great in keeping my husband's truck running smooth and steady. He drives a lot to and from work and it lasts a good while before needing changed.

My 2005 suburban has over 292000 miles on the engine - the only time I haven't used Castrol is when I couldn't find it ! I'm sure it has helped keep it alive and running !!

Does the job without breaking the bank. We have to have 10 qts just to change the oil in the truck so it's nice when it doesn't cost $50+ just for the oil before we even count the filter and disposal (and that's with free labor).

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.

I need to add some extra oil to my car from time to time in between oil changes and it is good quality with a reasonable price.

I find it works best for my vehicle. It runs great with high mileage. Castrol oil is the only brand I use fir all my vehicles.

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 put it in my oil reservoir every 6000 miles I like the oil because it doesn't break down. My truck runs smooth.
