Castrol GTX High Mileage is the premium part-synthetic motor oil specially formulated for vehicles with over 75,000 miles. As vehicles age, they change, and some of these changes can result in costly repairs or replacements. Catalytic converter failure is one of the most common  and costliest problems faced by higher mileage vehicles.All motor oil contains phosphorus to prevent engine wear. Phosphorus is an industry-recognized catalyst poison. Castrol GTX High Mileage is specially formulated with less phosphorus than other leading oils, replacing it with advanced technology invented and patented by Castrol that helps prevent catalytic converter and emission system failure. It delivers unsurpassed protection against sludge, wear, and oil burn-off, ensuring your engine remains in peak condition even as your vehicle ages.

Works well with engines having high mileage.

Works effectively in older vehicles with high mileage.

Offers a lower price point compared to others.

I bought my 01 Suburban in 2011 with 150,000ish miles on it.  Since I've owed the truck this is the only oil I've but in it.  I'll be doing another oil change this weekend and wouldn't think of putting in anything else inside Betsy Ross's engine.  The ole' girl is at 312,526 miles as of today and still running strong.

Best Oil For High Milage Engines

walmart.com

I bought this oil for my 2017 Kia Sportage that has 80,000 miles on it.  The oil appears to give my car a smooth operation and I have noticed a decrease in engine noise.  The bottle is quite large  so I use a funnel to avoid any spillage.

Noticed a Decrease in Engine Noise with this Oil

[This review was collected as part of a promotion.] Based on prior experiences and seeing the results of using this engine oil, it deserves to be called the best for its price tag. There are better oils, but they are also considerably more expensive. Castrol GTX is excellent.

I have 2 cars that I bought new and this is the only oil I use I change oil every 3,000 miles since I retired and don't drive long distances anymore. I am a firm believer of not changing to different brands of oil. The cars oil to me is like your blood always the same type ,  Both cars burn no oil and run great, completely satisfied with this oil both cars run great with great performance, Both cars are Toyota's one is a Corolla 2005 and the other is a Avalon 2001

Great Product

I use this for my 2005 Chrysler Town and Country Limited 3.8L engine. The car has 168,000 miles and is in great condition (garage kept since new). I wouldn't use it for my Toyota, since it's a blend, but it works great for the Chrysler. I still (even though it's not necessary) change the oil every 3000-3500 miles.

Great Price for Quality Oil

Always use Castrol. I've had rear main seals go and engine drive 10miles with no oil to make it honest (as a teenager 10 yrs ago) but siliconed it and filled oil again motor was fine. Use Castrol ALWAYS ever since. Walmart just happens to be the cheapest for the jug.  298,000 miles and still going.

Castrol, always !

Have been using castrol motor oil for many years in my 60's and 90's vehicles and will continue to stand by this product as my newer vehicles age.

Stop reading and try it...

There's no better quality than Castrol oil. I've used it for decades and its never let me down. Foreign or domestic vehicles are both well protected with Castrol oil.

Great quality at the best price around.

I used this on all three of my personal vehicles, my Honda Civic, my Infiniti G35 and my Nissan Altima.

All three of my car's favorite motor oil

I have always trusted Castarol it's the best quality oil on the market in my opinion! I had a 1985 Dale Earnhardt Chevy Monte Carlo Super Sport! It had over 400,000 miles on it when I sold it and didn't use a drop of oil or miss!

Best

I was searching for full synthetic oil and this showed up. Forgot to check the fine print and ended up with blend.  I will never again shop for oil at Walmart.
