Oil Change Essentials
To keep your 2023 Chevrolet Express 2500 running at its best, it’s vital to stick to the manufacturer’s oil recommendations. This includes choosing the correct oil type, knowing the oil capacity, and determining when to change it.

A) Recommended Oil Type, Capacity, and Change Intervals
- Oil Type: Synthetic 5W-30 motor oil is recommended for this model. High-quality synthetic oils like AMSOIL Signature Series or Mobil Super 5W-30 ensure optimal lubrication and stand up to the high temperatures generated by this engine.
- Oil Capacity: The engine requires 6 quarts of oil, including the oil filter. Maintaining this level is crucial to preventing overheating and ensuring all engine components are properly lubricated.
- Change Interval: Under normal conditions, aim to change the oil every 7,500 to 10,000 miles. However, if the van operates under heavy loads or in extreme conditions, reduce the interval to around 5,000 miles. For the most accurate interval, consider oil analysis. This helps determine the oil’s condition and ensures you’re changing it at the right time.
By using synthetic oil and adhering to these intervals, you’ll enhance fuel economy, reduce engine wear, and keep your van working as hard as you do.
B) Synthetic vs. Conventional Oils
Choosing the right type of oil boils down to your van’s needs. Here’s a quick comparison to help make the decision easier:
Synthetic Oil:
- Offers consistent performance in both hot and cold temperatures.
- Provides long-lasting durability and enhanced engine cleanliness.
- Resists sludge and deposit formation better than conventional oils.
- Typically allows for extended oil change intervals, saving time and money.
Conventional Oil:
- Contains more impurities and breaks down faster in high-heat environments.
- Requires more frequent oil changes.
- Better suited for older vehicles or those with low mileage to keep costs down.
Given the demands placed on the 2023 Chevrolet Express 2500’s engine, synthetic oil is the superior choice. It minimizes wear and tear, even in heavy-duty applications, making it the reliable option for work vans.
C) Product Comparison: AMSOIL Signature Series vs. Mobil Super Synthetic Blend
- AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil
- Pros: Outstanding engine protection, resists oxidation, supports longer drain intervals (up to 25,000 miles.)
- Cons: Higher upfront cost compared to other brands.
- Best For: Drivers who prioritize top-tier performance, long intervals between oil changes, and high-mileage protection.
- Mobil Super™ 5W-30 Synthetic Blend
- Pros: Affordable, good performance in moderate conditions, provides reliable engine wear protection.
- Cons: Does not last as long as full synthetic oil.
- Best For: Cost-conscious drivers who maintain oil changes more frequently.
Both options meet the needs of the 2023 Chevrolet Express 2500, but AMSOIL stands out for its extended performance, making it a better fit for busy schedules and demanding workloads.
