For the 1987 Isuzu Pickup with the 2.2L 4-cylinder Engine Code [U] Diesel Turbo, the engine oil capacity is 6 quarts when performing a service with a filter change. Recommended viscosities include 10W-30 for temperatures below 30°C, and 15W-40, 20W-40, or 20W-50 for temperatures above -14°C. AMSOIL recommends Signature Series 15W-40 Max-Duty Diesel Oil (DMEQT-EA) for outstanding wear protection.
What oil does a 1987 Isuzu Pickup 2.2L Diesel Turbo take?
The engine requires an oil with a CF specification. Viscosity selection should be based on your operating environment. For temperatures below 30°C, 10W-30 is appropriate. If temperatures rise above -14°C, you may use 15W-40, 20W-40, or 20W-50. In extreme cold (below -14°C), 5W-30 is an option, though the AMSOIL lookup notes that SAE 5W-30 is not recommended for sustained high-speed driving.

Diesel maintenance notes for this vehicle
Given the turbocharged nature of the 2.2L [U] engine, maintaining turbocharger health through proper oil viscosity and frequent oil changes is critical. Additionally, diesel injection systems from this era are sensitive to fuel quality; regular replacement of the fuel filter is a primary maintenance priority to prevent injector fouling or pump wear.
Common diesel oil-related concerns and how AMSOIL products may help
Maintaining a vintage diesel engine requires addressing specific operational stresses. The following table outlines common concerns for this vehicle type.
| Concern | Why it matters | AMSOIL Product | How it may help | Limitation |
|---|---|---|---|---|
| Turbocharger Wear | High-speed rotation requires constant lubrication. | DMEQT-EA | Provides extreme-pressure protection and maintains viscosity. | Requires regular oil changes. |
| Engine Wear | Diesel combustion creates high pressure/heat. | ADPQT-EA | Delivers up to 4X more wear protection. | Does not repair existing damage. |
| Extreme Temperatures | Fluctuating climates affect fluid thickness. | DMEQT-EA | Excels in extreme temperatures. | Follow viscosity guide for specific temps. |
Common maintenance concerns for this vehicle
- Turbocharger Lubrication: Ensure oil viscosity is correct to prevent turbo failure.
- Fuel System Integrity: Regular fuel filter changes are necessary to protect sensitive injectors and pumps.
- Cooling System Health: Monitor for leaks or degradation in gaskets and hoses.
- Belt and Timing: Check belt tension and timing component integrity, which is common for small-displacement diesel engines.
Recall, TSB, and manufacturer communication notes
Official NHTSA recall research for the 1987 Isuzu Pickup returned no recall records at this time. However, owners should always verify open recalls by VIN, as applicability can depend on production date, trim, and equipment. Official TSB research was not included in this draft; please consult a dealer for manufacturer communications.
About this vehicle
The 1987 Isuzu Pickup is part of a lineage of compact trucks with significant historical importance in the global automotive market. These vehicles are closely linked to the Isuzu Faster series, which was manufactured across several generations (including KB and TF model codes) between 1972 and 2002.
The specific configuration discussed here features a 2.2L 4-cylinder diesel turbo engine with the ‘U’ engine code. This engine sits within Isuzu’s broader reputation for producing durable diesel engines and commercial-grade components. Historically, these pickups were designed as versatile workhorses, often utilized for light commercial duties or reliable personal transport in various global markets.
Because many of these vehicles were marketed under different brand names within the General Motors portfolio, owners may find that parts compatibility often extends to other brands from that era. This lineage eventually transitioned into the modern Isuzu D-Max series, which replaced the Faster/KB models worldwide. Owners of this vintage diesel engine should focus on high-quality filtration and diligent fluid management to ensure longevity.
Common questions about this vehicle’s diesel oil and maintenance
What is the oil capacity for my 1987 Isuzu 2.2L Diesel?
The capacity is 6 quarts when including a filter change. Always verify the level after refilling.
Can I use 5W-30 in this diesel engine?
While 5W-30 is listed for temperatures below -14°C, the AMSOIL lookup notes that SAE 5W-30 is not recommended for sustained high-speed driving.
What oil grade does my Isuzu require?
The engine requires an oil grade of CF.
How often should I change the air filter?
While specific intervals aren’t listed, using a premium media filter like the WIX Air Filter (46116-EA) can help reduce engine wear and maintain OEM service intervals.
What coolant should I use?
AMSOIL offers options like the Passenger Car & Light Truck Antifreeze (ANTPC1G-EA) which is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free.
How do I check for recalls on my Isuzu?
You should verify open recalls by using your specific VIN through official manufacturer or NHTSA channels, as recall applicability can vary based on production date and equipment.
