CastrolEDGE 5W-50 Advanced Full Synthetic Motor Oil, 1 Quart, Pack of 6

Using this in my Polaris Ranger 900 for years. Cheaper than Polaris OEM oil and I know for sure what I am getting.

Full synthetic oil, pretty good price, meets the specs for my Polaris

If you want a high performance oil with good engine protection this 5w50 is it.

Kind of hard to find that weight- sure easy to order and was delivered to the door. Decent price too

The media could not be loaded. Good quality oil I use in my 96’ Hardbody to keep er alive at almost 261,000 miles. Original UNOPENED engine.

good product, fast shipped, great

I was a pioneer user of the first Castrol Syntec that used to come only as 5W-50 until some years ago I let an article talk me into not doing the extra expense of synthetic oil for my vehicles, it read that the problem with all types of oil was the additives breaking down, the same for mineral as synthetics. Well, I respect the experts, but for whatever reason the difference is so noticeable that I am not going back ever to minerals. This particular weight seems to work extraordinarily with all engines, from 4 to 8 cylinders. They love it and respond with a smooth start and run, and just as when I used it before, the engine from the oil cap to whatever you uncover is clean, so far not a trace of wear out (like oil consumption) and that makes me very happy. So I am not an expert, just a convinced customer that this oil is worth every extra penny and more.

Was recommended by Roush Performance to use this on my 2019 Ford Mustang GT with Roush Phase 2 Supercharger (750hp). So far so good!
