Castrol EDGE, engineered with FLUID TITANIUM, provides superior motor oil strength for gasoline engines that work harder due to higher engine pressures, helping your vehicle to maximize performance. Advances in engine technology have led to increased power and efficiency, meaning engines work harder and under higher pressures than ever before. The only thing keeping metal engine components apart is the oil, so it needs to be strong and remain strong. Castrol EDGE is our strongest and most advanced range of engine oils. Castrol EDGE, boosted with Fluid Titanium technology, doubles its film strength, preventing oil film breakdown and reducing friction. Castrol EDGE 5W-30 A3/B4 is formulated for highly tuned four-cylinder and latest technology engines that operate at higher temperatures. Its exceptional characteristics ensure that all engine components from the valve train to the bearings are fully lubricated to provide the strength for maximum engine performance.

Provides excellent viscosity and engine protection.

2012 Chrysler 300 with 87k miles... 
Castrol is a great choice in oil. Do some research and see for yourself. My car runs quieter and responds like new when I use this brand. This is my first time using this particular quality of their product, but I am observing the same smooth results. If you are the DIY type, I think you will benefit from paying attention to this oil. Everything these days is priced with a question mark, but this is not painful. Just a  habit of mine... filter changes only at 3-4k miles when using full synthetic long milage "oils". I have no confidence in filters lasting the life of long term oil. Same filter for 10-20,000 miles? REALLY? I don't trust that plan... not unless I'm investing top dollar in a super filter! My filter is topside in the engine bay--easy access. So why not?

This is a no-brainer...

[This review was collected as part of a promotion.] I've used Castrol over the years and it's always been fine. The price for a 5 qt. bottle at Walmart was icing on top.

Oil is oil right ? No it's not really. You need to make sure it's for your car. And when you're not quite sure you can't go wrong with Castrol synthetic. You can find what u need by putting ur car reference before you search for your oil it's Really that easy. …rob442

Good oil Great buy

I have been using different Castrol full synthetic for decades.  My prior vehicle a 1997 Jeep Cherokee that Castrol kept both oil-burning and engine wear free, that finally died from frame failure from New York winter salt.  My ride since, a 2017 Subaru Forester with 177000 miles on Castrol Edge, switched to Edge High Mileage now.  Again, engine kept in great shape.  Castrol has not disappointed me in thirty-five years.

Castrol Does Not Disappoint.

I use this oil in my old Toyota cars that call for 5W30. It does not turn dirty , ( black), as conventional motor oil would. Walmart is always running sales on this oil too which is great. Castrol has quite the reputation  as a good engine oil. Been around for many years. Highly recommend for the do it yourself oil change person.

Top notch brand

This oil is the only oil that hit all the wickets that Jeep recommend for the engines. I have a 5.7, 3.8, 3.6, now 2.0 turbo we run now 5W30 on 5000 mile intervals. Also the same as the oil filter. Other words I am a Mobil one fan. Two of my sons and wife run only Mobil one.

[This review was collected as part of a promotion.] I work and do oil changes on several vehicles and have for close to 50 years. You can't beat Walmart's price plus I can buy quality oil too.

[This review was collected as part of a promotion.] Use this product regularly for my vehicle oil changes. Prices could be lower.

[This review was collected as part of a promotion.] Castrol oil has been my favorite for the last 30 years in all my vehicles.  For high performance and engine protection

I was really shocked with this oil once I've always used it I was shocked because it started snacking and smelling after 2,000 mi and I ended up changing it at 2700 because I was worried about lifter ticks and things like that I did not like this oil for the first time.

[This review was collected as part of a promotion.] Didn't have my product available
