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

Quality oil at a reasonable price

Arrived undamaged with no leaking bottles. Shipped from west coast to east coast and arrived unscathed. Happy buyer.

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

What's to say, the auto stores don't carry 5/50 and that is what my car needs. So far I have ordered this same oil 4 or 5 times and have always gotten all 6 quarts. 5 stars :-)

good product, fast shipped, great

Good. Got for my S/C Gt500.

Completely satisfied.

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.
