    • Great Price for a Great Oil - Recommended!
Size: 160 Fl Oz (Pack of 1) Style: 5W-30
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. We believe, as a family, it is important to give an honest and accurate review to assist others so they can make good purchasing decisions that can benefit them and their family. And not be lead to cheap, unwanted purchases that are scripted by advertisers to buy their products. We are a family that believes in a minimalist lifestyle while trying to be green as much as possible in all departments of our life. As we care to leave something, anything, of this planet to our grandchildren so they may enjoy it as we have. ... show more

    • Best Motor Oil for Easy DIY Oil Changes!
Size: 160 Fl Oz (Pack of 1) Style: 10W-40
I recently used this to change the oil in my 2010 Subaru Forester for the first time. I was a bit nervous, but this product made the process simple. First off, the oil itself is top-notch. My car runs smoother and feels more responsive since the oil change. The engine noise is quieter, and it seems to be running cooler as well. The performance improvement was immediate and very noticeable. The 5-quart container is also very convenient. It has a sturdy handle and a secure cap, which made pouring the oil into my car easy and mess-free. After I refilled my car, I used the same container to hold the old oil. It was great not having to find another container for disposal. I couldn't be happier with Castrol GTX. It made my first DIY oil change a breeze, and the results are fantastic. If you're looking for reliable motor oil, I recommend this product. Five stars all the way! ... show more
