NAICS 811191 – Automotive Oil Change and Lubrication Shops covers maintenance services focused on routine vehicle care, including engine oil replacement, filter changes, lubrication of chassis components, fluid level checks, and related inspections for light- and medium-duty vehicles. This sector supports fleet operational readiness by ensuring compliance with preventive maintenance schedules and extending vehicle service life through standardized lubrication protocols. In the government contracting landscape, these services are critical to sustaining mission-critical vehicle fleets operated by federal, state, and local agencies, particularly those with high-mileage or 24/7 operational demands. While not a high-dollar procurement category, this NAICS plays a foundational role in logistics and transportation readiness, often contracted under maintenance support contracts or vehicle fleet management programs. No contractor data is available for this NAICS code, indicating that no single entity has emerged as a dominant federal supplier in this space. The competitive landscape is likely fragmented, with small businesses, local automotive service providers, and regional fleet maintenance contractors serving localized government needs rather than national prime contracts. No agency data is available, suggesting that procurement activity is dispersed across multiple departments with vehicle fleets, such as the General Services Administration, Department of Defense, Department of Homeland Security, and U.S. Postal Service, without a dominant spending pattern. The market is characterized by low entry barriers and high geographic fragmentation, creating opportunities for small businesses and local service providers to secure task orders under blanket purchase agreements or GSA schedules. Demand is steady and predictable, driven by mandatory maintenance cycles rather than project-based spending, making this a reliable niche for contractors with certified technicians and compliance with federal vehicle maintenance standards.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 811191 work as a small business.

$11.0M
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
