Review: It removed P0420 code in Sonata 2017 - I purchased a car that had run 32000 mile only. I drove another 40000 miles with TOTAL quartz 9000 but P0420 code never get dismissed. I tried so many product like engine flush, injector cleaner, valve cleaner, Oil saver, cataclean, catalytic system cleaner, 98 octane petrol. Nothing happened seriously.( P0420 has gone due to 98 octane petrol but coming immediately under harsh acceleration and remained for 2 to 3 months). But right after 200 miles on castrol high mileage oil 5w20 oil. The code has gone and not coming back at all. Amazing!!!. Add to above I received 2.5% more gas mpg compared with TOTAL oil Review: Solicito factura - Solicito factura, buen producto ## Features - Phosphorus Replacement Technology to help extend the life of the emission system - Reduces leaks, oil burnoff and power robbing deposits - 15,000 miles between oil changes* - Meets or exceeds the following specifications: API SP/SN PLUS/SN/SM ILSAC GF-6 | Meets engine test requirements of Chrysler MS 6395 | Meets Ford WSS-M2C945-B1 | Meets Ford WSS-M2C960-A1 - *Or one year, whichever comes first ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01CRYHNII | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #81,735 in Automotive ( See Top 100 in Automotive ) #829 in Automotive Oils | | Brand | Castrol | | Brand Name | Castrol | | Compatible with Vehicle Type | For vehicles with over 75,000 miles | | Container Type | Bottle | | Customer Reviews | 4.9 out of 5 stars 1,770 Reviews | | Global Trade Identification Number | 00079191231432 | | Included Components | Motor Oil | | Item Type Name | Motor Oil | | Item Weight | 0.01 Ounces | | Liquid Volume | 160 Fluid Ounces | | Liquid volume | 160 Fluid Ounces | | Manufacturer | Castrol | | Manufacturer Part Number | 15906D | | Model Number | 03143C | | Package information | Bottle | | SAE J300 Viscosity Grade | 5W-20 | | Size | 5 Quarts | | UPC | 079191231432 | | Unit Count | 160 Milliliters | | Vehicle service type | For vehicles with over 75,000 miles | | Viscosity Level | Low to Medium | ## Product Details - **Brand:** Castrol - **Liquid volume:** 160 Fluid Ounces - **Package information:** Bottle - **SAE J300 Viscosity Grade:** 5W-20 - **Vehicle service type:** For vehicles with over 75,000 miles ## Images ![03143C Edge High Mileage 5W-20 Advanced Full Synthetic Motor Oil, 5 Quart - Image 1](https://m.media-amazon.com/images/I/61AQnjgg5kL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It removed P0420 code in Sonata 2017 *by V***I on 9 January 2024* I purchased a car that had run 32000 mile only.
