Castrol GTX High Mileage 5W-30 Synthetic Blend Motor Oil, 5 Quarts

Great oil, I have always used this brand on all of my vehicles. Great price too.

I've been using this oil for a very long time in my 2003 Toyota Tundra. Packaging was fine. My truck has about 300K miles and going strong.

Put this in my car and it works as expected.

High mileage Castrol synthetic blend has been outstanding for my 2019 Ford Ranger with 130,000 mi. I absolutely think this is the right product and has kept me running smoothly. I change it every 7500 miles.

Has taken my avalanche to 272000 miles on original engine would recommend this brand of oil

Trusted oil been using it for years, great quality cheap price

I personally do not exactly choose one brand of oil over another. This oil seems to be as good as any to me. I chose the high mileage variant because I can only assume there is a reason to do so in a higher mileage older vehicle. The price was right and matched the price at local stores. Since I was able to plan ahead, I ordered from Amazon and had it shipped saving me the trip to the store. I much prefer to do my own oil changes for the savings and to know it’s not rushed or done incorrectly. Will probably stick with this brand going forward for my old pickup.

Received a great price for a great oil. But sadly since that great price I have only seen that price available to Prime Members.I have been using Castrol GTX since the 1980's and have always sworn by it being it has never let me down. I have never had an blow a seal, gasket, leak or burn oil while using Castrol GTX. And that is saying a lot as I use to be very hard on my vehicles, and can still be from time to time. One time I busted a hole in my radiator by accident in a parking lot over 15 miles from home. Having no tools or anything with me to fix the problem and being it was late night on a friday I had no choice. But to drive the car home as fast as I could before I lost all the radiator fluid and in turn over heating the car. Well long story short, the car made it home but was long out of antifreeze and the temperature gauge was buried in the red. Fearful for the engine I allowed the vehicle to sit over night to cool off. And the next day she started right up and was as good as always. I have always credited that moment to the fact I had Castrol GTX in the car and in turn is what saved the engine from the excessive heat. As I have not had the same luck other brand names of oil, as I have replaced two engines while using the brand name M. one.Due to my history with and without Castrol GTX motor oil, when I made my recent purchase of a high mileage Chevrolet Blazer 4x4 as a fun, toy around vehicle to haul things with and to play in the snow. Of course I drained the old motor oil out and gave her a fresh batch of Castrol GTX. I did the same for our other car as well. I would easily recommend this product to my friends and family.The oil arrived safely and in a timely manner. I was actually surprised they could ship motor oil as I figured that would be a hazard, but I guess the post office knows better.
