Works great
This is the fourth time I have purchased this oil. What does that tell you? Great product at a great price! Does the job and I think my 1978 VW bug will agree!

Castrol GTX 10W-40 Conventional Motor Oil, 5 Quart Jug
I have been using Castrol GTX brand oil for 40+ years without any oil related problems, i trust it. My local parts store does not carry the 10w-40 conventional oil any more, guess it does'nt move fast enough and it's not for newer vehicles. So i was happy to find it on amazon, and i get it straight to my door. Castrol quality, excellent value, highly recommended.J.R.

Good recommendation by mechanic
Purchased several times for a 2015 Hyundai Sonata Sport. Recommended by my mechanic. I had issues with the oil recommended by Hyundai. Since using this product, the issue has not reappeared. Castrol is a good brand. It is not excessively overpriced. Even though the manufacturer does not recommend it for my car, it has extended the life of my engine.

Conventional motor oil of America. Make oil great again
I’m glad I got this. It truly does keep my motor from seizing up or knocking holes in its own sides. I don’t like the smell at first, but I’ve got used to it now. Also if you do buy this, I recommend only for use in the motor. It doesn’t seem to work real well in the radiator and I had to throw that out after draining it. I was going to try the red stuff next. I do like the size of the 10/40 jug.
