Product Description

Castrol GTX High Mileage motor oil remains a trusted choice among drivers with high-mileage vehicles. No need to fret 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 even safeguards your emission system. Surprisingly, 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.

What was in this bottle?

What was in this bottle?
We have ordered this item from Amazon before and never had a problem, but the one we just opened was not good. My son opened it and began to pour it in his car when my husband noticed it looked dark, we then asked him where the foil top was when he opened it and he showed us a silver piece of what looked like duct tape. (see pictures) My husband said it looked used. I contacted Amazon right away so that they could check their inventory, and I am returning the product to them. I have never had any problems with any orders from Amazon so this clearly blew my mind. Who would do such a thing?
