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.

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!

Best price for a 10W-40 motor oil
This Castrol oil is getting hard to find on store shelves. The 10W-40 oil is for our high mileage , small, 4 wheel drive pickup. Very happy to find it by the case on Amazon.

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.
