Diesel maintenance notes for this vehicle
Diesel engines in the Transit platform require rigorous adherence to fuel filtration and oil change intervals. Because these engines are sensitive to fuel quality and soot buildup, maintaining clean filters and high-quality lubrication is essential for turbocharger performance and emissions system longevity.
Common diesel oil-related concerns and how AMSOIL products may help
Diesel engines face unique stresses such as soot loading and extreme temperatures. The following table outlines how specific AMSOIL products can support your maintenance needs.
| Concern | Why it matters | AMSOIL Product | How it may help | Important Limitation |
|---|---|---|---|---|
| Soot Loading & Wear | Soot can increase engine wear and impact performance. | DZFQT-EA | Delivers 6X more wear protection based on Detroit Diesel DD13 testing. | Requires proper service intervals. |
| Contaminant Buildup | Small particles can cause significant engine wear. | EAO17-EA | Provides 99% filtering efficiency at 20 microns. | Filter must be changed per interval. |
| Extreme Temperatures | Temperature swings affect viscosity and lubrication. | DZFQT-EA | Excels in extreme temperatures and maintains proper viscosity. | Not a substitute for mechanical repair. |
Common maintenance concerns for this vehicle
Owners of the 3.2L diesel Transit should focus on several key areas to ensure long-term reliability:
- Fuel Quality: Diesel engines are highly sensitive to fuel quality; regular fuel filter inspections and replacements are vital.
- Soot Management: Monitor oil condition closely, as soot buildup can impact turbocharger health and emissions systems.
- Emissions Systems: Proper maintenance of the diesel exhaust fluid (DEF) and fuel injectors is a common area of research for Transit owners.
- Turbocharger Health: Ensuring consistent lubrication and clean air intake helps protect the turbocharger from premature wear.
Recall, TSB, and manufacturer communication notes
Official NHTSA recall research for the 2018 Ford Transit 350 returned no records at this time. However, owners should always verify open recalls by VIN, as applicability can depend on production date, trim, and specific equipment. Official TSB (Technical Service Bulletin) research was not included in this draft; please consult a professional dealer for the latest manufacturer communications.
About this vehicle
The 2018 Ford Transit 350 is a versatile light commercial vehicle that serves as a primary tool for cargo and passenger transport. Following the retirement of the E-Series vans, the Transit became a cornerstone of Ford’s commercial lineup in North America. The ‘350’ designation indicates it is designed for heavy-duty light commercial use, capable of handling significant payloads.
This specific model features a 3.2L 5-cylinder diesel engine. While often discussed alongside the more powerful Ford Power Stroke V8 engines found in Super Duty trucks, this 5-cylinder variant is specifically engineered for high torque and durability within the Transit platform. Because it is a specialized diesel component, maintenance requirements—such as fuel filtration and specific oil viscosities—differ significantly from gasoline-powered counterparts. Owners often focus on managing Diesel Exhaust Fluid (DEF), maintaining turbocharger health, and ensuring strict adherence to service intervals to mitigate the effects of soot and heavy-duty commercial use.
Common questions about this vehicle’s diesel oil and maintenance
How much oil does my 2018 Ford Transit 350 3.2L take?
The engine requires 12 quarts of oil when performing a service that includes a filter change.
What is the recommended oil viscosity for this diesel engine?
For all temperatures, 0W-30 or 0W-40 is recommended. For temperatures above -29°C, 5W-30 or 5W-40 may be used. If using biodiesel (B6-B20), use SAE 5W-40 API CJ-4.
Can I use AMSOIL Signature Series for my Transit diesel?
Yes, the AMSOIL lookup lists DZFQT-EA as a high-performance option for this application.
What should I use for the automatic transmission?
For the 6R80 transmission, AMSOIL recommends ATLPK-EA or OTLQT-EA.
How often should I change my diesel oil?
While specific intervals depend on driving conditions, AMSOIL products like the Signature Series are designed to support extended drain intervals. Always consult your owner’s manual for manufacturer-recommended intervals.
How do I check for recalls on my Ford Transit?
You should verify open recalls by using your specific Vehicle Identification Number (VIN) through official Ford channels or the NHTSA website.
Disclaimer: Always verify all fluid capacities, viscosities, and torque specifications with your vehicle’s owner’s manual or a verified VIN lookup before performing maintenance.
