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.

  • Motor Oil Solution
Size: 160 Fl Oz (Pack of 1) Style: High Mileage Configuration: 5W-20
Castrol is one of the best oils on the market, in my 50+ years of working on my own cars. This purchase is a great deal as it is at good price especially considering that it is delivered to my home. No need to travel to an auto parts store. Where I live that is a huge benefit.

  • It’s Oil.
Size: 160 Fl Oz (Pack of 1) Style: High Mileage Configuration: 5W-30
I personally do not exactly choose one brand of oil over another. This oil seems to be as good as any to me. I chose the high mileage variant because I can only assume there is a reason to do so in a higher mileage older vehicle. The price was right and matched the price at local stores. Since I was able to plan ahead, I ordered from Amazon and had it shipped saving me the trip to the store. I much prefer to do my own oil changes for the savings and to know it’s not rushed or done incorrectly. Will probably stick with this brand going forward for my old pickup. ... show more

  • 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
