Take a look at the varnish deposits in this picture. These are the results of a severe high temperature deposit test.  The one at the far right is AMSOIL Synthetic 15W-40 Diesel oil and the others are major brand petroleum diesel oils. (left to right: Chevron Delo 400, Cummins Premium Blue, Shell Rotella T, AMSOIL 15W-40). The test clearly shows that AMSOIL keeps engines cleaner longer than other major brand diesel oils do. Which oil would you rather have protecting your engine?

We are here to help you learn the facts and show you how you can use AMSOIL motor oil and get a superior product and also increase the  performance and add to the longevity of your Ford Powerstroke Diesel plus save time and money. The Powerstroke Diesel is an excellent vehicle and exceptionally well engineered by Ford Motor Company and International.  In our opinion it is one of the best vehicles ever produced, however there are ways to make the performance and longevity even better with AMSOIL Synthetic Lubricants.

Synthetic Oil Proven to Prevent Turbocharger Bearing Seizure. One of the many specific areas on a turbocharged engine, such as the Powerstroke Diesel  which can clearly benefit from the use of synthetic motor oil is the turbocharger.  When a turbocharged engine is shut off immediately after a high speed run, "heat soak" occurs from the engine, and it considerably increases the temperature in the turbocharger.  Over a period of time this can lead to deposits that can block the oil flow to the turbocharger bearings, leading to turbocharger seizure.  Synthetic engine oils that are inherently more thermally stable than petroleum engine oils have been shown to keep turbochargers considerably cleaner than petroleum engine oils.  A poor petroleum oil will give turbocharger seizure, caused by blocked oilways, in under 100 hours of a severe "heat soak" test cycle.  A good petroleum oil will survive for 100 hours but with considerable deposits and incipient blocking. A good synthetic oil will maintain the turbocharger in almost "as fitted" condition. Read on to learn the many more ways in which your Powerstroke  Diesel/ Ford Diesel can benefit from synthetic oil.

Specifically for the Ford Powerstroke Diesel AMSOIL engineers and manufactures a 15W-40 Synthetic Heavy Duty Diesel and Marine Oil (as well as Series 3000 5W-30 Heavy Duty Diesel Synthetic) that when used in conjunction with the AMSOIL EAO-99 engine oil filter on the 7.3L Turbo Diesel will allow you to travel 25,000 miles/1-year between filter changes and 25,000 miles/1-year between oil changes for normal duty service  If you use oil analysis you can usually go longer than 25,000 miles.  Other AMSOIL benefits include reduced sludge and deposit formation, extreme temperature protection, improved fuel efficiency and rust and corrosion prevention and it does not void any new vehicle warranty. AMSOIL Synthetic Lubricants meet and exceed all API rated and Ford specifications.

AMSOIL  has introduced a new premium, high efficiency cartridge oil filter utilizing nanofiber technology for Ford 6.0L diesel engines ranging from 2003 to 2006. The new EaO-88 is the world’s first oil filter cartridge for diesel applications using advanced submicron full synthetic media. The EaO-88 provides an efficiency of 98.7% at 16 microns, significantly higher than the OEM filter. Click here to see these products: Ford PowerStroke PowerCore® Filters

The other option is to install an AMSOIL Dual Remote By-Pass Filtration System.  With this system you only change your oil when oil analysis indicates.  The AMSOIL Ea full flow filter is changed at 25,000 mile intervals and the by-pass filter is changed at approximately 25,000 miles for normal duty service.   The AMSOIL 15W-40 Synthetic Heavy Duty Oil  or the Series 3000 5W-30 HDD does not break down like conventional petroleum based motor oils, is much more shear stable and does not have the waxes, paraffins and by-products that come out of crude oil that is pumped from the earth.

The by-pass filter removes the particles that cause wear in your engine down to less than one micron (a micron equals 0.001 mm) and keeps the engine oil analytically clean so you do not need to change your oil for a long time, while still getting far better protection than someone that changes their oil every 3000 miles. We are experienced at installing these units on Powerstroke Diesels (and all vehicles) and can provide you with exact installation instructions, tips, bracket prints and photographs.

Oil analysis provides a big return for your small investment by extending equipment life by preventing premature component failure, reducing maintenance cost by eliminating unnecessary component changes and a decrease in downtime due to premature scheduled maintenance as well enabling calculation of optimum drain intervals that will reduce lubricant costs and assure maximum equipment protection.

Your regular full flow engine oil filter will only remove wear particles down to the 20-25 micron range. The filter cannot remove finer particles because the oil must be filtered quickly while removing most of the particles present in the oil, except the particles below the 20 micron range. A study completed by the Federal Mogul Corp. analyzing over 7000 main and connecting rod bearings concluded that 60% of all engine wear occurs in the 5-20 micron range. This is why no matter how much you change your current full flow oil and filter, regardless of the brand, that you still are not removing the particles that cause the greatest wear in your engine.

The primary 10 micron filter, located in the Horizontal Fuel Conditioning Module (HFCM), performs initial fuel cleansing before sending the clean pressurized fuel to secondary four micron filter, mounted to the oil filter housing. The secondary fuel filter includes a fuel pressure regulator and an orifice on top of the housing that bleeds air out of the housing and back to the fuel tank. Following its trip through the secondary filter, fuel is returned to the HFCM, where it is either directed to the tank or returned to the primary filter. AMSOIL SDF-88 Oil Filter for Ford 6.0L Diesel PowerStroke™ Applications   SDF-88 Constructed of a highly efficient synthetic blend media, the AMSOIL SDF-88 Oil Filter provides increased engine life and improved filtration efficiency. The AMSOIL SDF-88 is a cartridge-style filter located on the top of the engine. When the filter is removed during servicing, the oil filter housing drain valve automatically opens, draining the oil from the housing to the pan. The oil filter base of the SDF-88 directs oil to the oil filter, engine oil pressure switch (EOP), engine oil temperature sensor (EOT) and turbocharger oil feed. The filter base also includes an anti-drain back check valve, keeping oil in the filter assembly when the engine is shut off.

Don’t let you local dealership tell you that you have to use their brand of oil to "maintain your warranty". This practice is not authorized or condoned by the auto manufacturers, but the fact is it still goes on. How a servicing dealership can essentially tell a customer that they have to use their lower quality oil to "maintain their warranty" is not only wrong but it is also illegal unless they provide it free of charge. There are Federal laws that protect you against this. Please read our Warranty Laws You Need to Know section of this website to learn more.
