Maintenance tips and oil specification
Choosing the right oil and version
For the 4.8L V8 in the 2015 Express 2500, a 5W-30 oil is typically suitable. Both conventional and synthetic formulations are acceptable as long as they meet the viscosity and any OEM specifications noted in the manual. If your region or insurance requirements specify Dexos, use a Dexos-approved 5W-30.
Checking and topping off
To check oil level: park on level ground, run the engine briefly or let it cool, remove the dipstick, wipe it clean, reinsert, then pull again to read the level. If the level is below the full mark after draining and replacing the filter, add oil in small increments (about a half-quart at a time) and recheck. Do not overfill, as that can cause engine damage or foaming.
Additional considerations
Be mindful that different service histories or aftermarket filters can shift the exact amount needed. If you recently replaced the oil filter, you’ll typically end up near the higher end of the range (around 4.5 quarts). If you did not replace the filter or drained the engine differently, the amount might be slightly lower. Always verify with the dipstick after pouring in oil.
For those doing do-it-yourself maintenance, keeping a small notebook of the exact quantity used during each oil change can help you gauge the right top-off amount over time, especially if you notice slight discrepancies between fills.
Summary
In short, the 2015 Chevy Express 2500 with a 4.8L V8 typically requires about 4.5 quarts of engine oil with a new filter. Use a 5W-30 oil (conventional or synthetic, as specified by GM), and always finish by checking the dipstick to bring the level to the full mark. Variations are possible based on drain conditions and filter changes, so rely on the dipstick as your final reference.
