You keep telling yourself that. GM almost went with Pennzoil Platinum as the factory fill for Corvette last year when Mobil's contract ran out, but Mobil swooped in with more money yet again.

It is a money game. Plain and simple. But you believe whatever makes you feel happy.

False. Where do you keep getting your bad information? Internet forums? Geez. While Champion does make both filters, they are not identical filters and in fact, they perform quite differently. K&N filters have great flow, but suck at filtration. Mobil 1's, however, filter great, but restrict flow compared to other quality filters.

They are fine. It is an average filter that does its intended job. Go back to post #29 in this thread and read what I posted.

EVERYTHING is a "money game."

As long as brand X performs to GM's standards they will recommend them. What makes brand X the "choice" of GM is a different. It comes down to $$$. Brand X. Y, and Z could all perform th GM's standards..... What seperates them is not their performance, but who is willing to put up the $$$.

This is no different than NASCAR. Race teams use/recommend different products (oil, car batteries, etc) and use different cars/race engines (Chevy, Ford, Dodge, Toyota). Why is that? I'll tell you.... It's not because brand X is better than brand Y, but because brand X is willing to pay up the $$$.

Sponsorship....

If I own a large company with millions of customers and you want to provide a service to go along with my product I will listen. If you want me to recommend your company to service/work with my product, then I have two criterias:

A: Your service does not damage my product in anyway and meets my standards.

B: By recommending you, I will be allowing you access to MY customers, thus making you more $$$. As compentation, I want you to pony up a TON of $$$$ up front.

Don't like my proposal? No hard feelings, I've always liked brand Y better anyways..... I will "recommend" them

Seriously hope there is a ton of sarcasm in your post. Lucas is no better than any off the shelf oil at Wally World. Mobil 1 and Fram in the same sentence? Seriously?

It actually shouldn't matter. Dexos1 is a performance specification, specifically one that replaces GM6094M and GM4718M, and is supposed to be backwards compatible. That is, that anything labeled as meeting Dexos1 is an acceptable substitute performance wise for anything that was on the 4718M list.

dexos™ is recommended by GM for use in all its vehicles except those with Duramax diesel engines requiring the use of API CJ-4 engine oil. dexos™ is fully backward-compatible and can be used in older vehicles. It is specified in the owner's manual for all 2011 and later model years, with the exception of Europe where dexos™ is specified starting in model year 2010.

dexos1™ is designed for use with gasoline engines and replaces GM-LL-A-025, GM6094M and GM4718M

It matters because dexos is a "money game" from GM. If you think a semi-synthetic is as good as Mobil 1 or Pennzoil Platinum for example just because it has the dexos label, then you are very naive and have fallen victim to the GM money marketing machine.

IMO there are better off the shelf oils for less money.

Pennzoil Platinum, Mobil 1, Valvoline Synpower, and Quaker State Ultimate Duarability are all great synthetic oils off the shelf that can be had for less than Royal Purple and provide excellent protection. Amsoil is another boutique oil like RP that can be had for less as well.

Oh yeah, I'm naive for actually reading the performance spec.

Dexos1 requires a NOACK high temp volatility rating of <13. It also has a really low tolerance for oxidation. Those were the main requirements underlying 4718M. In all areas, Dexos1 requirements are at least as stringent as 4718M and in some case more so.

The only base stock that can reach those levels of performance is high quality Group III and Group IV, in other words, the same types of base stock used in oils like Pennzoil Platinum and Mobil 1.

There is a marketing aspect to Dexos1 with the "official licensing" but at the base it is STILL a performance specification and if an oil meets the performance spec, it meets the performance spec.

BTW, wanna venture a guess as to who makes that "terrible semi-synthetic" for GM?

Betcha $$$ the base stock is not much different than the rest of Mobils oils....
