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
