Castrol GTX 20W-50 Conventional Motor Oil, 1 Quart

I've used Castrol oil for decades. I have no reservations. In years past, I used Castrol 10-40w in Ford 15 passenger vans traveling 500 miles per day, 7 days per week. At 15,000 miles per month with paying passengers, I had to be sure I was doing the best I could. I would replace the vans at 2 year intervals with 360,000 miles on them. I never had a problem finding a buyer for these vans and many sold without any advertising.

I have been using Castrol GTX since 1976. I had been using another oil before then and after having to tear down an engine I could not believe the build up on the engine parts. The engine had less then 80,000 miles on it. Now I have had several vehicles that have gotten over 200,000 miles on them with no oil related problems. I will continue to use this oil.

The product and size available is perfect and delivery time was accurate. The packaging was awful! The box was not sealed, and slightly damaged. Luckily none of the oil containers were damaged, which would have been a big mess. Also left very visible.

This is my choice of oil in my vehicles! I have been using this type oil for over 35 years and my 1997 f150 has over 300,000 miles and still going! I'd like to see it back in the stores!

The quality of this speaks for it self used for 20 years plus and motor is very sound change about 4000 to 6000 miles still running

Great quality reasonably priced and on time !!!

ONLY OIL USE FOR MY 1995 FORD RANGER

It would be nice to have 20W50 available at more locations. I have to drive past two super centers to get to the nearest Walmart location that carries it. This is my choice for summer operation in my motorcycle (dry clutch) and for the hydraulic system of my zero-turn mower. But I have been thinking about changing to 15W40 for the motorcycle since it is easier to find.

my tahoe started knocking at idle around 150k miles i was scared to use 20w50 over recomended weight 5w30 i used this 20w50 gtx oil and no more knocking or any wierd lifter noise runs smooth for the last 17k miles as long this oil keeping my engine in good working with no noises im sticking with it and it also help keep oil pressure above 40 psi. thank you castrol gtx 20w50 you saved me an engine rebuild.

They sent 2 jugs of oil it was leaking all in the box and yall have not send the other 2 jugs not at all it looks like yall would send all 4 at the same time
