Great Price for a Great Oil - Recommended!
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. If you have a Prime Membership, you can almost always find Castrol GTX cheaper on Amazon than at any retail location even with a coupon or on sale. We were not paid nor discounted in any way, shape or form for giving our honest opinion here of this product as a review to assist others.

As we care to leave something, anything, of this planet to our grandchildren so they may enjoy it as we have.

Since switching to this oil, I've noticed a significant improvement in my engine's overall cleanliness and efficiency. It runs quieter and feels more responsive, which is a testament to the oil's ability to keep everything well-lubricated and free from harmful deposits. The synthetic blend formulation offers excellent protection in both high and low temperatures, making it a versatile choice for various driving conditions.

Good oil.
Been using it almost exclusively for 180,000 miles in my truck. Still dont have to add between changes at 5000 miles or so. The packaging was an abomination. I got 3 of the 5 quart jugs & am unsure why they weren't just shipped in the Castrol packaging.. upright side by side. Instead they were packed in the worst possible configuration in a large flat box laying down with the spot for a 4th jug just sitting empty. I had a hard time carrying the box into the garage as it wanted to bend in 1/2 & kept trying to slip out of my arms. Very very poor. It's only the shipper's extra care that enabled the package to arrive intact. But hey that little bit of tape around the lids protected everything (he said as he rolled his eyes).

Tenía mis dudas pero parce ser que está bien desde que le hice el cambio a el día de la reseña recorrí un poco más de 50 kilómetros si hubiera algo malo ya hubiera "avisado" note que es un poco más obscuro que el que compro tradicionalme pero hasta el momento todo bien.
