Castrol GTX 5W-30 Synthetic Blend Motor Oil, 1 Quart

This is good oil if you are going to do your own oil change. I have used it for years and found that if it changed at 5,000 mile intervals, the engine internals stay clean and do not develop sludge.

My vehicle has high mileage and this is the brand I always use. It has good consistency and it is a high quality product. I travel a lot and this products is always easy to find wherever I may be .

I like how it helps my car run way better than the cheaper versions. It helps it run smoother and cleaner. I can go further between changes with this oil. I recommend this brand of oil. It is worth the few extra dollars.

Bought this product for our scooter. Works well, easy to use. Great for smaller engines and longevity for the engine. Buying name brand has worked well for us with regard to engines and other oil needs.

Very good oil which I used in my riding lawnmower and push mower and been using this oil for many years! No problem with either engine and base stay clean and no major engine problems.

Only motor oil my husband will use. We have been using Castrol oil for all of our cars for many many years. Even got the kids using it too. Never ever had any problems with it.

I use Castrol every time I change my oil. By far, it is the best oil out there. My car performs good and runs clean. It is also affordable which is a definite plus.

Best oil for trucks hands down. Better grade than oem. This is the only brand of oil I will buy. Great for cars, trucks, and diet bikes. High mileage for high mileage vehicles and this grade if not available.

I like this oil and weight for my older Chevy truck. I've never had any issues using it. And I like the heavy weight here in the Florida heat. I've had issues with other brands of synthetic oil leaking past seals.

We started using this oil many years ago and it gives use exceptional service. Our engines get very good gas mileage and oil holds up very good. Unless they stop selling it , we will buy this brand of oil.
