Amazon has become my go-to motor oil merchant
I could not be happier with this oil. I have been using Castrol GTX regular and High Mileage oils in several cars for 8+ years so you can imagine that I am satisfied with the brand. As for Castrol's GTX High Mileage 20W-50, I have been using it for a while, first purchasing it at parts stores, but this oil was phased out of many stores in my area. I bought most of the stock I could find in the local stores and then pondered the question of what to do when I use it all up. I searched for this oil on Amazon, merely on a whim, and I was ecstatic to find that they sold it for a price much lower than what I was paying in the auto stores. An oil change on my car takes about four quarts, so I first purchased two of these five quart containers. After using them up and a having a great experience purchasing them on Amazon, I went ahead and purchased four more containers to stock up. I do much of my own vehicle maintenance and working on cars a hobby of mine, so oil changes are something that I always do on my own. I use this Castrol in a 1992 Volvo 240 Wagon with 250,000 miles which is a daily driver and I will not use anything else for oil at this point. A specialist for these cars recommended that I try a 20W-50 oil in the B230F in my Volvo. I have been able to keep my engine running very smoothly for its age and mileage through regular oil changes and the use of this quality oil. I am confident that recurrent use of this oil will help me push the Volvo many more miles before needing to do an overhaul (the engine is yet to be overhauled, but that should be no big surprise for anyone who has experience with a B2XX engine Volvo).

Help for worn out oil pumps...
My very old car's check oil light lights because the oil pump is worn out & the service manager explained that it's buried deep in the engine, replacing requires slinging the engine & about a quarter of a major engine overhaul to replace it, $1,800 bucks. I normally use 10W-30, but this 20W-50 keeps the check oil light extinguished, so I'm using it... Next step is 10W-60 & then a trip to the finance company... Highly Recommended if you need it...

Lo mejor para mi auto
Tamaño: 5 Quarts La luz de revisión de aceite de mi coche muy viejo se enciende porque la bomba de aceite está desgastada y el gerente de servicio me explicó que está enterrada en lo profundo del motor, reemplazarlo requiere colocar el motor y aproximadamente un cuarto de galón de una revisión importante del motor para reemplazarlo, 1.800 dólares. Normalmente uso una 10W-30, pero esta 20W-50 mantiene apagada la luz de control de aceite, así que la estoy usando... El siguiente paso es el 10W-60 y luego un viaje a la compañía financiera...
