It’s time to readjust the oil in your F-150. She standing in the oil aisle of the components store down the street, just staring at all of the different-colored bottles and also wide-ranging numbers. Which one execute you choose?

To gain a much better grasp that what works finest in your Ford, let’s take a short look at some of the revisions do from the 1997 model year come now.

The Engines

For 1997, Ford majorly redesigned the F-150 for the very first time since 1980. Rounder styling, much more interior space and an all-new engine lineup to be the 10th generation’s hallmarks.

A 4.2-liter OHV Essex V6 replaced the 4.9-liter OVH I6, if the Triton 4.6- and 5.4-liter SOHC V8s replaced the 5.0- and 5.8-liter OVH versions. Those three engines ongoing as the choices through the 11th generation (2004–08).

In 2009 Ford reduce the 4.2-liter V6 due to the closure the the Essex plant in Windsor, Ontario. 2 versions that the 4.6 liter (two- and three-valve variants) and also the three-valve 5.4 remained. FoMoCo acquired busy again because that the 2011 lineup (beginning that the 12th generation) and offered one all-new selection of powerplants. Six cylinders changed with the basic 3.7 and also optional direct-injection 3.5-liter EcoBoost V6. Both V8s were changed — the 4.6 to be bumped through the 5.0, and the 5.4 gave method to a 6.2.

What Ford Recommends


Ford advised, and also was shipping vehicles from the factory with, SAE 5W-30 motor oil in the majority of your engines since the 1990s. Climate in January 2002, Ford authorize a Technical service Bulletin currently recommending the use of SAE 5W-20 instead of SAE 5W-30 motor oil. The 4.2-liter V6, 4.6-liter V8 and also 5.4-liter V8 from 1997 come 2002 to be all listed as vehicles to it is in serviced with the new recommendation. It to be “an improved formulation to boost fuel economy.” indigenous 2002 onward Ford recommended SAE 5W-20 in almost every one of their engines (4.2-liter to the 6.2-liter); the exception being the 3.5-liter EcoBoost. They introduce SAE 5W-30 for the direct-injection 6 cylinder.

Ford supporters multigrade oil consumption rather than single grade due to its broader temperature operating range.

What is artificial oil?

Now that we recognize the factory’s desired grade, those the difference between the quart that oil that expenses $5 and the quart that prices $10?

The distinction in price in between the various oils comes mostly from the synthetic procedure. Synthetic oil is not polished from entirety crude oil prefer conventional motor oil is. Artificial is distilled, purified and also broken down right into its simple molecules. It consists of ingredients that room artificially created and included to the petroleum base.

During the process to create artificial oil the hydrocarbon molecules end up being uniform in size, shape and weight. This permits the oil to administer superior chemical and mechanical nature when compared with typical motor oil. Better wear protection, resistance come oxidation and thermal breakdown, and also decreased evaporative accident are several of the benefits fabricated oil brings to your engine. All of it adds up to increased horsepower, enhanced gas mileage and smoother engine operation.


Should girlfriend use fabricated oil in your engine?

Simply put, the is a remarkable product. The just detractor is price, but that can be mitigated by the extended company intervals. Countless vehicles don’t require an oil change for 10,000 or 15,000 miles.

Early commercially available synthetic oils garnered a reputation for destroying seals and causing leaks, but that simply doesn’t happen by switching between the oils. Artificial oil is 100% compatible with modern automotive gasket and seals. If the engine leaks through synthetic, it will certainly leak through conventional.

What about synthetic blends?

There was also a myth that convention and also synthetic oils need to never be mixed, but man-made blends have been in use due to the fact that 1966 as soon as the French lubricant agency Motul introduced the an initial one. There to be a fear that to switch earlier and forth, the engine would should be completely flushed. Artificial oil is compatible with conventional oil and synthetic blends.

Ford’s very own Motorcraft brand is a fabricated blend. That what came brand-new in your truck (2003 version year and later), yet they aren’t the just ones that will certainly work. Common blends have no much more than 30% synthetic oil combined with the standard base. The blend is a compromise between conventional oil’s price and full synthetic’s performance.
