Summary as of Oct 31, 2026. ## Pros - Reviewers consistently report smooth, dependable engine performance in both newer and high-mileage vehicles, including one with roughly 130,000 miles. - The high-mileage formula is credited with helping reduce oil burning and leaks, though results vary by engine. - Its synthetic-blend formulation helps keep engines cleaner by reducing sludge buildup. - Users report strong acceleration and reliable operation over extended use. - It has been used successfully in cars, a pickup truck, a classic performance vehicle, and a generator when 5W-30 oil was specified. - Several reviewers say its performance compares favorably with more expensive oils. - Long-term users praise its consistent results and say they would purchase it again. - Multiple viscosities are available across the product line, making it easier to match the oil to a vehicle’s requirements. ## Cons - This is a synthetic blend, not a full-synthetic oil, so buyers seeking maximum full-synthetic performance should look elsewhere. - You must confirm that your vehicle requires SAE 5W-30 and meets the manufacturer’s required certifications before using it. - Reported improvements in oil consumption, leak prevention, and engine longevity are based on individual experiences and are not guaranteed for every vehicle. - The six 1-quart bottles are convenient for topping off or smaller oil capacities, but a larger container may be more practical for some oil changes. ## Specifications | Attribute | Value | |-----------|-------| | UPC | 079191064405 | | ASIN | B008BOG0PG | | Size | 1 Quart, Pack of 6 | | Brand Name | Castrol | | Unit Count | 192 Fluid Ounces | | Manufacturer | Castrol | | Model Number | 06440 | | Liquid Volume | 6 quarts | | Container Type | Bottle | | Item Type Name | Motor Oil | | Viscosity Level | Low to Medium | | Customer Reviews | 4.8 out of 5 stars 8,769Reviews | | Best Sellers Rank | #284 in Automotive (See Top 100 in Automotive) #7 in Motor Oils | | Automotive Fit Type | Universal Fit | | Included Components | Motor Oil | | Manufacturer Part Number | 06440 | | SAE J300 Viscosity Grade | 5W-30 | | Compatible with Vehicle Type | For use in vehicles with over 75,000 miles, Passenger cars, trucks, and SUVs | | Manufacturer Warranty Description | 12 Months | ## About This Product Castrol® GTX® High Mileage 5W-30 is specially formulated for vehicles with over 75,000 miles.
