A New Oil Specification for GDI Engines

This year brought us a new specification for motor oil; ILSAC GF-6 / API SP. One of the primary goals of the new oil spec is to reduce incidence of two problems gasoline direct injection (GDI) engines have been experiencing. GDI blasts the fuel directly into the combustion chamber at high pressure. This leaves less time for the air and fuel to mix together. The resulting air/fuel mixture may burn unevenly which may generate a lot of soot. As the pistons move up and down, the soot gets mixed into the motor oil. The soot travels with the motor oil through the engine and causes wear. The most noticeable wear often occurs between the pins and bushings that hold timing chains together. As the bushing holes wear and enlarge, the timing chains stretch. Eventually the timing chains may stretch to the point that they slip across gear teeth or otherwise are unable to correctly connect the crankshaft to the camshafts. The computer generates a trouble code, the engine goes into limp-in mode and/or the engine stops running. GF-6 / SP oil resists collecting and circulating the harmful soot. GF-6, API SP and API SN PLUS on label The second problem, low-speed pre-ignition (LSPI), is also related to the uneven burning of air/fuel in GDI engines; specifically, turbocharged GDI engines. When running at relatively low RPM and under heavy load, like when moving away from a dead stop, severe knocking may occur inside the cylinders. Scientists figured out that traces of engine oil mixing and burning with the air/fuel mixture contributes to the damaging engine knock. GF-5 / SN-Plus spec oil was released a couple of years ago to combat this problem (watch for the “Plus” after SN). The new GF-6 / SP oil helps with both the soot and knock problems. Ford has produced the most turbocharged GDI engines. Small 1L, three-cylinder Ford EcoBoost engines power Ford Fiestas, and big 3.5L, six-cylinder EcoBoost motors are in work trucks that rack up a lot of severe-duty (towing, dust, etc.) miles. The soot and knock problems have been studied most thoroughly on EcoBoost engines. The new specification actually requires that new GF-6 / SP oils pass tests running in Ford EcoBoost motors! GDI / Direct Injection in part descriptions and Info page These new oils, higher fuel injection pressures, intake manifold port injection coupled with GDI, etc. help solve these problems on older engines and prevent them on newer engines. GDI engine owners may be able to help the most by simply changing their vehicles' motor oil frequently and always using the correct oil. Instead of waiting for the longest, light-duty, oil change interval (often 7,000+ miles/11,000+ km), change the oil closer to the severe-duty interval (often 3,000 miles/5,000 km). You can check to see if your specific vehicle's engine uses GDI by looking at the “Info” pages and part descriptions for the engine's Fuel Injectors found under “Fuel & Air” in the RockAuto.com catalog. Find the correct engine Oil for your vehicle under “Engine.” Oil is also listed by viscosity/weight under the “Tools & Universal Parts” tab. Note: The “A” in GF-6A means the oil is a viscosity/weight compatible with existing engines. The “B” in GF-B means the oil is only to be used in recent engine designs that require completely new viscosity/weight oils such as 0W-16. Tom Taylor, RockAuto.com

So in the quest for fuel mileage and engine longevity change your synthetic oil more often. Most people don’t change their own. So much for saving money.

From the #1 Filtration post in Practical Lubrication and Filtration.

 

Byproducts of Oil Oxidation/Degradation/Soot. Unless the additive package is depleted leading to amalgamation, the detergent/dispersant package of a modern motor oil will hold these particles to 0.5 to 1 micron. Until they amalgamate they are spherical. They are also relatively soft.

 

The post is saying that the soot load is drastically higher is GDI motors CONSUMING the dispersant and detergent package rather quickly. The cure is more frequent changes.

 

I would expect the SP oils to have additional loads of both.

My reason for posting this was with a so called better oil it still says to change the oil sooner/more frequently. 

My point from the start of me joining this site was shorter OCI's.  

As I have said you do what makes you happy. 

Shorter OCI's make me happy.

The reason for my answer was simple. The reason for more oil in the crankcase and more frequent oil changes are the results the quest for fuel mileage. The cost of more frequent oil changes negates savings from better gas mileage. If we’re nearing 3-4K oil changes as rule instead of an exception. We’re going backwards creating a dirty engine. Back to dirty combustion. Not to mention more hardware internally. I don’t call that progress. People get all excited about frequent oil changes. Weird.

I get where you're coming from. But a vehicle is not and never will be cost effective. You can do somethings to help with cost but in my book oil changes are not one of them.

Look, if you guys would just start using Amsoil SS and filter you’d all be much much happier individuals. Lol, kidding, or am I ?

What’s short OCI’s now a days, 2k, 3k, 4K? At what mileage does cheaper oil really start to loose it’s ability to protect your engine? Most of us will never drive under normal conditions as driving conditions vary. Personally and my personal experiences, I think frequency of oci’s is definitely a plus but cheaper oil is just cheap oil and I’d imagine using a cheap oil filter quadruples the added wear as your oil remains dirty throughout the interval. Just my 2 cents.

Gal stopped in front of the house the other day in a Prius delivering from PRIME. Rex and I were getting back from the evening walk. I asked her, "Your using your personal car for deliveries"? She replied in the affirmative.

 

I mentioned that the cheapest vehicle on my property (with four wheels) cost about $1.37 a mile to drive. 

 

She smiled and said with youthful dismissiveness..."It's a Prius. It gets great mileage"

 

People in general don't know how expensive it is to own/operate these machines. My fuel cost this year has run just under 7 cents a mile. The other $1.30 is all other cost.  It's a long list. 

 

There no longer is a 'break even' on a car/truck point in ownership. You will always have more in it that it is ever worth. They are not an investment. They are an expense. Collectors not withstanding naturally. The five year cost of ownership is nearly three times the strike price. It's why I hang on to them until they drop. The longer that takes the fewer I buy the smaller my needs.

 

I couldn't spend enough on oil and filters to change that.

So the manufacturer's in their quest to satisfy Uncle Sam, transferred that cost to the consumer.  Well, not really, just moved it from one category to another but to make the government happy, it will cost us more, as it always does when dealing with them.

I was lucky to be able to experience the performance vehicles of the late sixties through the second coming in the mid 90s to the present. I also experienced the fail attempts of some early diesel cars from GM. And the early small cars and small engine attempts from the big three. Opening the door of the Honda- Toyota invasions. I owned many cars and trucks including the 5.7 diesel. Exciting. The 2000s through the recent past GM was clicking on all cylinders ( pun intended). Their large SUVs and trucks became indestructible ( Fords too). Now to get a couple few extra MPGs out of said vehicles they’re back to experimenting. Maybe with the turbo 4s and V-6 to satisfy the extreme fuel mileage guys. They’ll give us at least one true V-8 like ford and Toyota. Now we have Frankenstein V-8s from GM that in order to make it all work the maintenance cost go up. If - when the internals go freaky becomes an extra repair to get going costing thousands. There’s always Toyota and Honda once again.

From cruising the Honda and Toyota forum, they are not the vehicles of old.  Problems popping up with new models as well.  Honda and their engines have increased in fuel dilution issues.

Another reason for larger oil capacity is due to fuel dilution.  Imagine how fast the oil would loose it's lubricating properties if it was still a 5qt system and soaked with fuel.  Not long at all which would require back to the days of 3k oil changes.

My daughter now has my 17 Camry. She’ll probably hand it to her daughter. The same fate my wife’s Elantra with another daughter. That 05 is still going. The Camry gets 10K oil changes. Now close to 90K miles. We’ll see. The Elantra has 7500 oil changes.

What oil are you using? Amsoil? Then I agree with the extended OCI's.
