The truth about GF-5

  • Better turbocharger protection
  • Better sludge protection
  • Better emission system durability
  • Better fuel economy


What's not to like???

That all depends on whether the "no change in performance" for wear protection applies to the conditions inside your particular engine or not. For the vast majority of engines on the road, GF-5 is probably a great thing. For some particular older design features... maybe not so much. Maybe fine. The Sequence IVa test is ridiculously mild. Come on, a little 4-cylinder Nissan economy engine for the cam wear test? Try that test with a 426 Hemi or a Ford 427 and if the cam wear is within spec, then I'll have no complaint.


Beyond that I have a bit of a philosophical problem with the whole GF5.com website. Its a company promoting a regulation because they "have the solution" and want to tout it. It distills down to the flowchart at the top of the "why GF-5?" page. I DO NOT believe that regulation should ever drive design. End of story.

There is a bunch of information available on the GF-5 website link above. If you take the time to study it, you will be answering questions on BITOG rather than asking them. The first licenses for GF-5 are anticipated for 3Q 2010, with availabilty shortly thereafter.On the link, you may enter your email address to get updated with progress reports as they have their meetings. FWIW---Old tommy
 
There are some concerns with some manufacturers of high moly oils and turbos.
 
One thing that is interesting... the differences between the two specs are the perceived weaknesses in the current oils we're using (or value added features with zero cost, which I doubt exist).

Interesting that there is focus on cleanliness and dispersants, and none on anti-wear. This validates the attitude around here that any oil will properly lubricate your vehicle, but the extended OCI's with "better oils" are basically due to their ability to keep your engine clean and free of deposits (and not turn acidic, of course).

My thoughts exactly. Really are no wear issues with modern engines and oils. Which suggests that most of what we discuss here is all an obsession with many people. Arguing over ppm of wear. etc.
 
I really want to know where they came up with the spiderweb visual aid. Setting aside the notion that Arachnia may be running things ...that just doesn't make it for me in some Gestalt way. Very odd way of expressing something.
 
What's wrong with it? Just curious. Infineum has their little GF-5 thing going on. Similar layout.
 
It should narrow down the difference between full synth and mineral oils. Or, its just going to make cheap oil more expensive as it approaches the synth price and then becomes a synth.

I have nothing against the usage of better base stocks and newer additive technologies.
 
The oil manufacturers are going to have a hard time making this standard and they have said so. Trying to improve one thing many times affects another in a negative way.
 
The way I see it, at least for my 3 vehicle fleet, is I'm better off stock piling more oil. No increase in wear protection, maybe a little more cleaning? A-rx or MMO can fix that. E-85 protection, I don't use the stuff. Probably a big price increase, maybe its just me but I see little value for my current fleet.

90% of vehicles on the road if run with regular & proper OCI's shouldn't need "extra cleaning" and those that do generally run a synthetic with a more robust additive package anyways.

I see this as a big price increase and nothing more...

Stock up on GF4 oils people... Just another way to part consumers from their hard earned cash IMO!

A bar graph would simply show where things stay the same or have been augmented/improved. You've got all these tangents that do little beyond connecting dots.

You've also got 5 tiers ..which one would assume that each represents each GF evolution ..while GF4 protrudes into GF5 .and GF5 idles in GF4 (assuming that the divisions mean anything at all).

Inverting the would look just as strange to me. If simple rays were used with circle for divisions it would seem more sensible. Skip the connecting lines ..skip the web. The creator must have had a childhood romance with "connect the dots" in some radial persuasion.

Again, it's a Gestalt thing. My visual perception features/defects/lacking/peculiarity.

You don't have a problem integrating the depiction ..and I don't either ..after a fashion, but I wonder what inspired it. It would have never entered my head to do it this way.

If you were responsible for creating a visual aid to depict the GF evolutions ..with no prior influence/direction infused into the mix, would you have chosen this manner to do it?


In short, it's alien to 99.44% of the ways I've ever seen progress or differences graphically shown.

That's all

Edit: This has similarities to ..hmm..something like M1 0w-40 to me. I see the stuff shearing routinely ..I butt into the conversation where all the marvels of it are being discussed ..and I poke my head in and say "Hey .ahh..guys ..why is shearing a good thing here ..while every other oil it's a defect" ..and the group pauses for a moment ..I get a look of "what's he talking about?

" and a reply of "Oh that ..it's nothing of importance" ..and am summarily dismissed as the conversation returns to its previously interrupted point.

Good stuff. A better question will be how will GF-5 affect the best oils in the business or more specifically the brew and not just the designation of GF-5 by itself??

Also too, if under a current system, an oil is not energy conserving (ML), does that mean they will try to re certify for GF4 *and* energy conserving or would the GF4 automatically include energy conserving status?
