Just doing some quick research - it appears this will replace the 4718M spec. Do you think this will void the warranty if it is used in vehicles that use the 4718M?

Rob
They say it is good with all 2010 and older, even the 4718M spec. Basically they are saying you can still use Mobil 1 since it meets dexos 1 specs or dexos 1.

If a dealer chooses to, they can stock only dexos 1 and put it in everything except a diesel which uses dexos 2.

I think it will be closer to $7/quart or less.

Are these things that would show up in the results of UOAs (used oil analysis)?

I don't know what would show up in oil that has gone say 10K in an engine. Might be interesting. Of course the 8 cylinder oil burners would never make it to 10K.

The column on the right is about 8100 miles and was for Syntec 5w30.
The column on the left is about 6500 miles and was for Pennzoil Platinum 5w30.

It's sold as a full synthetic.

Then dexos1 should see similar results I am guessing.

I'm surprised it wasn't done sooner.. Adding the Mobil 1 to the Vettes & the HHR SS & etc, has to cost more that an in-house brand would..

$7 a qt for semi-syn... Naw !!!!

Harley did it back in 1999, when they realized they had a Hot running motor & dino oil was breaking down. So consumers were using better aftermarket Synthetics.. So HD came up with their own lame so-called syn oil..

I don't believe that going 8K-14K between oil changes is good for an engine.
I have personal knowledge of a Class 8 diesel going One MILLION miles without an oil change using a part synthetic.

IMHO to blame a MINUTE oil specification on engine failure is nothing but a cop out and is purely profit motivation driven. Blame it on the consumer and you void an expensive warranty claim due to design flaw. Keep the consumer AFRAID of voiding a warranty claim keeps dealerships in business!

Oh, and I have ran a GEO METRO 15,000 miles between oil changes.....I sold it with 450,0000 miles showing on the OD.....head replaced twice due to burnt valves...typical for the 3cyl design.

The concern of the above diesel was that it would not have all other components subjected to wear properly maintained simple because the said components would be serviced at a typical oil change interval and unless the routine interval was observed those components might no get proper maintenance. The only adverse effect was that hydro carbon emissions went up with mileage. The EPA monitored this test and the emission level stopped the wide spread adoption of a new standard......this was in 1995!

IMHO there is no real reason that a gasoline engine of modern design should not be able to exceed 50,000 mile oil change interval. My belief is that profit is the goal and not longevity.

GM came out with a 'new' specification for the simple reason that it NEEDS the money from frequent dealer visits to be profitable.

IN these discussion I've been accused of many things, but I'm not attacking GM. These tactics are nothing new. Mercedes or you name the high dollar marque has been using these tactics for YEARS!

It's all about maximizing profit without and real improvement in design.
