Every Hummer model has specific oil requirements set by the manufacturer. Thinner full synthetic formulations are common on newer engines to optimize fuel economy and emissions. Select your exact trim and year above to find correct specifications.

Our database covers 7 Hummer vehicles spanning from 2006 through 2010, giving you the exact oil grade (e.g. 0W-20, 5W-30), capacity in US quarts, compatible oil filter part number, and manufacturer-recommended service interval for every model.

Whether you drive a Hummer H3 4WD, a SUV, or a H3T 4WD, the correct oil specification is just two clicks away — select your model above, then your year.

Hummer oil change intervals vary by model and year. Modern Hummer vehicles (2015 and newer) typically use full synthetic oil with intervals of 7,500 to 10,000 miles. Older models may require conventional or synthetic blend oil changed every 5,000 miles or 6 months.

For Hummer vehicles, using the manufacturer-specified oil filter is equally important. Each model page shows a compatible aftermarket filter (Fram, Mobil 1, or OEM equivalent) alongside the oil specs so you have everything needed for a complete service.

Always cross-reference with your vehicle's owner's manual for the most accurate specification, especially for newer models or special trim levels with different engine configurations.

Oil Grade

Most modern Hummer vehicles use 0W-20 or 5W-30 full synthetic. Check your specific model for exact grade.

Change Interval

Typically 5,000–10,000 miles depending on year and oil type. Severe driving reduces this by 25–30%.

DIY Cost

Most Hummer oil changes cost $45–$95 at a shop, or $25–$50 in parts for a DIY change.
