The 2015 Chevy Silverado remains one of the most dependable full-size pickup trucks on the road. Whether equipped with the fuel-efficient 4.3L V6, the popular 5.3L EcoTec3 V8, or the powerful 6.2L V8, using the correct engine oil is essential for maintaining performance, fuel economy, and long-term engine reliability.
Choosing the proper oil viscosity helps protect critical engine components from wear during towing, hauling, stop-and-go driving, and extreme weather conditions. Regular oil changes also reduce sludge buildup, improve engine efficiency, and help extend engine life beyond 200,000 miles.
What Oil Type Does a 2015 Chevy Silverado Use?
The recommended oil type for most 2015 Chevy Silverado engines is SAE 0W-20 full synthetic motor oil meeting GM’s Dexos1 specification. This oil provides excellent wear protection, fuel economy benefits, and superior cold-start performance.
Using non-Dexos approved oil may reduce engine protection and could affect long-term engine performance. Full synthetic oil is strongly recommended by Chevrolet for all EcoTec3 engines.
Best Overall Oil: Dexos1 Gen 3 approved SAE 0W-20 full synthetic oil such as Mobil 1 Advanced Fuel Economy or Valvoline Advanced Full Synthetic.
