One thing to remember with Turbo Diesels is the DPF regen cycle. Its hard on the engine oil. With up to 10,000 between oil changes, I don't know why you would want to extend it?
I think the 150 will treat you just fine, you just need to attack towing differently.

AMSOIL’s equivalent to Rotella T6 is the 15W-40 OE Synthetic Diesel Oil – not because of the viscosity, but because it is a Group III base-stock, and so is cheaper per quart than a true synthetic oil. But while the OE oil does deliver a cold pour point of -36, it only handles standard recommended oil drain intervals. The better choice is AMSOIL’s 15W-40 AME Premium Synthetic oil, which delivers a conservatively recommended oil-drain interval of 3X Ford’s recommendation, plus AMSOIL’s EA15K88 oil filter which delivers a 70% wear-rate reduction and 15,000 mile filter life. This extended 15k+ mile drain interval means that AMSOIL is the lowest-cost solution for HEUI oil changes, when annual maintenance costs are the measure instead of per-quart pricing. When adding the
AMSOIL remote bypass filtration system,
you can eliminate over 90% of engine wear and extend the drain interval indefinitely, as verified by oil sampling analysis.

VERY INSIGHTFUL into the realities of a daily driver Ford Diesel! I do NOT know which system Ford is using on the 3.0 ???

The 2007 6.4 to the present 2016 6.7L are unfortunately the worst, most risky odds for being able to extend drain intervals beyond the Ford recommendations. This is because the regeneration cycle for the DPF burns out the filter’s accumulation by over-fueling the cylinders (after burn completion) to put diesel fuel into the exhaust, which washes fuel down the cylinder walls into the oil.
This is because the
ACTIVE (not passive) regeneration cycle for the DPF burns out the filter’s accumulation by over-fueling the cylinders (after burn completion) to put diesel fuel into the exhaust, which has the piston rings unavoidably wipe unburned fuel down the cylinder walls into the oil. Due perhaps to unique details of the 6.7L engine design, Ford has not transitioned to the superior 2011+ DPF regeneration-cycle approach used by GM to avoid fuel contamination of the oil (see below) by use of a fuel injector in the turbo down-pipe.
“Passive” regeneration occurs during normal operation, due to high enough throttle & fuel-burn rates to take the internal DPF temperature above the ~1100°F threshold where the captured diesel fuel particles will be ignited and burned. Active regeneration of the DPF occurs when the exhaust back-pressure builds (diesel particulate matter, DPM, has accumulated enough to obstruct exhaust flow). To force a DPF burnout, the engine computer sprays fuel into the cylinders at the end of combustion so that the unburned fuel is exhausted into the high-temperature exhaust, raising the DPF temperature high enough to get burnout of the DPM buildup.
Because of the variable of Active Regeneration of the DPF, how the vehicle is used becomes a critical factor in oil contamination:
- Unfortunately, PowerStroke “daily driver” 6.4L and 6.7L commuter pickups in city driving are almost certain to experience a high frequency of active regeneration. [If a truck will be used in that way and you need to purchase a 2007+ model year, you should instead consider purchasing a 2011+ Duramax-powered vehicle, because the LML engine model changed the active regen approach by adding the Hydrocarbon Injector (HCI), which is simply a 9th fuel injector that sprays fuel directly into the turbo exhaust down-pipe, eliminating the need to over-fuel the cylinders post-combustion. So the HCI now injects all the diesel fuel directly into the exhaust stream during active regeneration (cleaning of the diesel particulate filter). This active regeneration strategy is unique to the LML, and will be used for the foreseeable future.]
- “Foreman” PowerStroke trucks are quite likely to experience active regeneration cycles, which can vary from occasional to frequent. Idling and low speeds with light loads will ensure a-regen. In this application, approach extended drain intervals with caution.
- Some fleet and “working” PowerStroke vehicles will experience little or no problem with this fuel contamination of the oil, because they are rarely in active regeneration: these are vehicles which are always adequately loaded and frequently driven in highway traffic with medium to high throttle long enough for the passive regeneration to keep the fuel particulates burned out of the DPF canister. Caution: OTR drivers must always rely on APU’s for stationary power, rather than idling the truck engine during lunch/dinner/sleeping.
So, the speed and severity of engine-oil fuel-dilution in these PowerStrokes is largely driven by driving habits. To clarify, a truck which is frequently well-loaded or hauling for 20+ miles at a time in warm to moderate temperatures is likely to put the DPF in the temperature range to burn out the accumulated fuel particles, so oil sampling analysis will probably show that extended drain intervals are possible with AMSOIL’s DME. But a PowerStroke which is a daily driver in the upper mid-west with a 10 mile commute, that seasonally pulls a trailer once or twice a month, is going to do most of its’ DPF burnout regenerative cycle by over-fueling of the cylinders after firing. In this case, while AMSOIL will provide superior protection and performance, drain intervals are restricted by fuel contamination and cannot be significantly extended – and this is where the cost-effectiveness of the AMSOIL OED makes a lot of sense.
So DPF-equipped “working” fleet PowerStrokes can likely deliver extended drain intervals with DME, particularly by adding an
AMSOIL Dual Remote Bypass Filter kit. This is because a bypass filter kit lowers oil-sump temperature, reduces the load on the additive package, and adds about two more quarts of oil capacity.
