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 governed by a 4-quart, 5W-30 API engine oil specification, a concise maintenance baseline for this medium-duty bus platform. Its reliability history is marked by a sparse complaint record of just seven total owner complaints and zero recalls. Because those few reported issues concentrate in the Engine & Engine Cooling category, the model year presents a largely clean historical profile, meaning that researchers investigating reported faults should focus their attention on the engine and cooling systems.
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.
