Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1995 P-Series MD Bus Chassis.
The 1995 Chevrolet P-Series MD Bus Chassis is a purpose-built commercial platform whose maintenance protocol centers on a 4-quart 5W-30 API oil fill, a straightforward specification that anchors its routine service schedule. Recorded reliability data for this model year is notably sparse, with zero recalls and only seven total owner complaints, the greatest concentration of which falls under Engine & Engine Cooling. That absence of recalls combined with such low complaint volume marks the 1995 chassis as a low-event entry in the P-Series reliability record, giving researchers a stable baseline rather than a profile shaped by recurring systemic defects.
Fluid capacities, tune-up values and fuel economy at a glance.
Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.
From the factory this vehicle uses a BCI 78 · 600 CCA battery. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

This engine holds 4 qt of 5W-30 API engine oil, 80W-90 · GL-5 in the differential, DOT 3 brake fluid. Torque lug nuts to 100 ft-lbs, the oil drain plug to 18.0 ft-lbs. The firing order is 1-8-4-3-6-5-7-2. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1995 Chevrolet P-Series MD Bus Chassis dominate in one area — the engine & engine cooling, 3 of 7 reports (43%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 1 a fire — a small share of the total, but worth weighing against the engine & engine cooling pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
