What oil are you guys using?

I was thinking about using Rotella T6 5w40. According to manual should be OK.

Rotalla T6 is widely available at about every auto store across the US. I havent seen 5w30 diesel oil on shelves.

5w-30 or 10w-30 is what is recommended for the 3.0. Nothing heavier. I have a friend who sells for Mobile looking into there compatibile oil for the 3.0. I’ll post his findings when I get them.

So I played in a monthly home poker game last Friday night, and one of the regular players is a PowerStroke Diesel mechanic at the local Ford dealer, and the oil you are thinking about using is what his recommendation was when I asked him about oil, so I think you have selected well.

The new 3.0 F150 oil has a spec wss-m2c214-b1. If whatever oil you use doesn’t have this spec Ford may not cover any issue under warranty. This spec may have us handcuffed. My Mobile salesman looking to see if they have a oil to meet this spec.

Just saying... that Ford has a special blend of Motorcraft oil with the F150 Diesel label on it. It was designed for the special lubrication requirements of the 3.0 Power Stroke Diesel. The oil is sold in two different viscosity's. One is the 5w30 for the colder temperatures and one is a 10w30 for the warmer climates.


I will be checking if my Ford Garage is using this oil for my first oil change. I would not be surprised that some dealers had not yet stocked the new oil. The Ford Video that I viewed stated that the oil used for the 6.7 should not be used for the 3.0 and vis versa.

Check out the Ford Video on you tube

John. You are spot on. My dealer had to order filters and oil for my first oil change. I’m sure some dealer don’t have it in stock.

I got my first oil change about 6 weeks ago. The dealer didn't have the filter or oil in stock. It took them 3 hours to track both down in the Denver distribution center.

Based on my research (no expert), I don't think Rotela 6 meets the extremely low friction requirement, though all major oil companies will soon have it. Castrol has oil that meets FA4 and Ford F150 Diesel spec.

@HonestJohn - Thanks for the info, as I am approaching my first oil change interval/service.

I watched the Ford TechTalk video and I'm sure this is going to drive Ford Service Managers and Techs crazy, as now they will need to stock/use a different oil between the smaller PowerStroke diesels.

I was planning to run Full Synthetic and I thought this news would throw a monkey wrench into the equation, as the video didn't mention anything about Full Synthetic...

I did a little more research and found that the 5W-30 is actually Full Synthetic according to this PDF: https://dadistributing.com/wp/wp-content/uploads/2018/08/Motorcraft_Oil_Comprehensive_Sales_Aid-logo.pdf

Note the description at the top of Page 5 and the table on Page 7 clearly delineate:
=> SAE 5W-30 F150 Full Synthetic Diesel Motor Oil
=> SAE 10W-30 F150 Diesel Motor Oil

I'll be stopping my dealer this week to ensure they have both the oil (1 Quart Bottle – XO5W30QFA) and correct filters in stock for my next service (based on comments by @Knifeman and @tal0362), as I know for a fact that I am the only person who has taken delivery of a 2018 F150 3.0L Diesel (other two they ordered are still sitting on the lot) from their dealership.

Quote from http://www.fcsdchemicalsandlubricants.com/main/quickref/oilchartUS.pdf
Check Owner's Guide for appropriate viscosity depending on ambient temperature, duty cycle and biofuel content.
Above 0°F (-18°C) - 50°F (10°C) use SAE 10W-30 FA-4
Above -20°F (-29°C) use SAE 5W-30 FA-4, or 5W-40 WSS-M2C171-F1, CK-4, CJ-4
Above -40°F (-40°C) use SAE 0W-30 or 0W-40 WSS-M2C171-F1, CK-4, CJ-4


This clearly states that regular shelf 5w-40 Rotella T6 is just fine for the 3.0L.

Oils meeting WSS-M2C171-F1 https://www.fcsdchemicalsandlubricants.com/main/additionalinfo/dieseloilsWSSM2C171F1.pdf

Google it.

There are Ford Tech talks on Youtube that seem to be published by Ford. They have a big don't do it circle around WSS-M2C171-F1....

My dealer said I should be very careful about the oil I let other auto mechanics put in the engine. He said, most don't mechanics know yet.. The wrong oil will void the warranty.

Post a picture of the big red circle. Also that big red circle could just mean its not recommended/optimal, but not necessarily unsupported as the manual and several other guides clearly state T6 5w-40 (or equivalent) is supported.

Yes a FA-4 oil is recommended, but a CK-4 oil is also supported.

Not according to the API web site. (API.org) FA-4 oil is not compatable with or interchangeable with the CJ-4 and CK-4 oils. These are are the ones who created the standard.

No one ever said there interchangeable. But for the 100th time. the F-150 MANUAL SAYS 5w-40 CK-4 OIL IS COMPATIBLE.

This is a picture from it. You cannot argue with the print in the manual.
