Description

Castrol GTX High Mileage motor oil is the 1 high mileage brand and remains a trusted choice among drivers with high-mileage vehicles. No need to worry over the decision between high mileage oil or synthetic oil because Castrol GTX High Mileage offers the best of both worlds. It combines the benefits of a synthetic blend engine oil, providing ultimate engine protection against sludge, wear, burn-off, and safeguards your emission system. Catalytic converter failure is a common cause of the dreaded 'check engine' light in high mileage cars, often attributed to phosphorous present in conventional engine oils. While phosphorous is included in oils for its wear-reducing properties, it can prove harmful to catalytic converters. However, Castrol GTX High Mileage Motor Oil features an advanced Phosphorous Replacement Technology. This innovative formulation replaces some of the phosphorous with a cutting-edge additive that ensures robust wear protection while preserving the health of your catalytic converter. When you prioritize extending the life of your high mileage engine and safeguarding your emission system, Castrol GTX High Mileage Motor Oil stands as the unrivaled choice. Experience its exceptional performance and discover the reliability it brings to your high- mileage journey.

    • Great oil and proven to keep engine clean
Size: 160 Fl Oz (Pack of 1) Style: High Mileage Configuration: 5W-30
Have been using Castrol GTX in all my Toyota vehicles for years. I have had valve covers off for gasket replacement and inside is super clean, no sludge. I change all my vehicles oil myself and this is a very good price through Amazon.

    • It's synthetic oil
Size: 160 Fl Oz (Pack of 1) Style: High Mileage Configuration: 5W-30
It's synthetic oil, works as advertised. No complaints and it's cheaper than local dealers price. Will buy again.

    • Only brand I use is Castrol GTX.
Size: 160 Fl Oz (Pack of 1) Style: High Mileage Configuration: 5W-30
My father was a mechanic since he was a teenager (in his seventies now). He's had more engines torn apart than I've had Reese's cups and at all different mileages. He told me he's never had an oil-related problem be evident on any engine that has had Castrol GTX as its standard. If you can get the conventional, it is one of the few made with mineral oil and not paraffin wax like a lot of other "national" brands are. He says that makes a difference. Now, I've only had a few engines apart, none of them more than once, so I can't speak to the same effect. However, I can say that Castrol GTX is the only -- the ONLY -- brand oil I've used in any of the vehicles I've owned and I've never had a problem from the engines after taking ownership. Our Chrysler 3.6L Pentastar had 30,000 miles on it when we got it and I've been less than strict on how frequently I've changed its oil (one time right after COVID we went about a year but only 7,000 miles), but it now has over 99,000 and is still going strong with no indication of oil or oil-related failure (coolant system and transmission are other stories). I've also only ever used Castrol GTX in the Pontiac 2.2L Ecotec. Same deal, drove it since nearly brand new (dealership handled the oil before I came into the picture). Now has just under 80,000 on it, zero mechanical problems. I'm not a GM guy but this has been a very good powertrain. I feel bad taking the used oil to the local shop for disposal since I buy it online (meaning they're not making money on me), but nowhere brick-and-mortar has it at as low a price as Amazon (that I've seen, at least). Plus, if they have Castrol, they don't have Purolator filters I use. Odd, that. Granted, I'm only saving about 5 or 6 dollars a jug, but being able to use the leftover on the next change, I just buy two or three at a time and store it until its time comes up. ... show more

    • Its oil.
Size: 160 Fl Oz (Pack of 1) Style: High Mileage Configuration: 5W-30
It's oil. Its reasonably priced. The car doesn't mind. The jugs survived shipping. I have one vehicle that specifically calls for Castrol brand oil. I know there are many equivalent choices but I just go with the suggestion. It has survived over 160k miles and still doesn't consume or leak a drop so apparently its adequate! I now use this as my standard oil in several other high mileage vehicles that call for the same viscosity. In a 205,000 mile warhorse, I was having oil related issues with a vvt solenoid. It would gum up before every oil change. I went so far as to buy the new solenoid but after switching to Castrol, the issue has disappeared. ... show more

    • Great oil
Size: 160 Fl Oz (Pack of 1) Style: High Mileage Configuration: 5W-30
Would definitely recommend this oil. My truck has 80k and it gets this oil, it's also 20yr old truck, but don't go over 5k miles between oil change. I never trust oils that go to10k, I belive its false advertising or not healthy for your vehicle.

It does what it is supposed to. Fairly priced for a synthetic blend. Comparable with most cars requiring this oil weight. Used in 2006 Subaru Impreza.
