Remove if major service is needed, not a big deal and no way anyone can tell. I do not want blowby getting recycled to my engine - bad on multiple fronts

The problem with straight 50 is there is no low weight oil blended in for cold start, so you're starting with pure 50 wt and that's pretty thick even at 80 F--when I add 15w50 in my engine on a warm day it flows slowly from the container.

Right, and 15W-50 is too thick for a street engine.

Honda's 2.0T sees higher load (20 psi boost) and Honda calls for 0W-20. I think that's crazy, but it shows that some manufacturers have no problem specifying very thin oils to reduce pumping losses, and the motors seem to be holding up (on the street)

Chevy calls for 0W-40 in this engine as of 2019, I trust their judgment

Do you know if the color of the label dexos 2 has a meaning ?

Some dude said to me that:
Blue is for diesel first
Green for unleaded first

Any remarks on that detail ?
Or is it BS?

As far as I am aware, DEXOS 2 label is blue, while DEXOS 1 Gen 2 label is green. They are two different standards.

put Amsoil in it, I mean Amsoil is the leader in synthetics has been since the mid 1970's.
all others just get their ideas from Amsoil. Been a dealer since 2006.

For anyone looking, the GM part number for the Mobil 1 ESP 0W-40 is 19353135. I called a dealer and was told $7.76 a quart. I work for a dealer, so he was helping me out, our GM dealer quoted me like $9 a quart!

It's good stuff but it's almost double the price of Castrol Edge 0W-40 I can get from Amazon for $21/5 qt. I don't see a clear advantage anymore. All these newer "extended performance" synthetics with additive packs are very good. Used oil analysis and various wear tests show relatively minor differences, especially for oil change intervals 5k or less. Conventional M1 is probably near the bottom of the pile.

This! ^^^^^^^^^^^^^^^^^^^^^^^

And Ammsoil is not Dexos to those who want to follow the letter of GM law. Can't beat Speedway with their $10 coupon for first order and an oil filter here https://www.speedwaymotors.com/Mobil...xoC7J4QAvD_BwE

If anyone can explain to me why dexos is little more than sales and marketing bullshit, I might consider using it - but I don't think anyone can, they will just keep paying DOUBLE THE PRICE for similar or worse oil!

Please don't tell me it will void the warranty to use non dexos, that's insane.

Dexos 1 has performance features that exceed those requirements of API SN/ ILSAC GF-5 in some areas and are less strict in others.

Dexos 1 requires performance to be enhanced over what API SN/ ILSAC GF-5 requires in the following areas; engine sludge protection, volatility, piston cleanliness, turbo charger protection, resistance to oxidative thickening, wear protection, seal compatibility, and corrosion protection.

Dexos 1 requirements for emissions systems durability, fuel economy and E-85 emulsion retention (use with gasoline containing alcohol) are somewhat less than what API SN/ ILSAC GF-5 require.

The Dexos 1 licensing program requires motor oil manufactures to pay a licensing fee to General Motors to use the Dexos1 approved logo; essentially making the sale and use of Dexos 1 motor oils a profit center for GM and increasing the cost of the oil.

Early on the concept GM had for the Dexos 1 licensing program required motor oil manufactures and end-sellers alike to pay a per-quart fee to GM for every bottle of GM Dexos approved oil sold.

In actual implementation though I believe this has changed to a flat fee per year for manufacturers and end-sellers. Since I’m not privy to GM’s decisions and because the Dexos 1 licensing program is still evolving and has changed more than once since its inception only GM and the manufacturers/ end-sellers who have entered the program know the actual fee’s that add to the retail price of Dexos 1 motor oil.

While a quite a few motor oil manufactures have started making oil that meets the Dexos 1 specification, at the time of this writing any number of motor oil manufacturers including Valvoline and Amsoil have balked at paying this fee saying it does nothing for the consumer but drive up the cost of the oil and are refusing to join GM’s program.

The reality for the consumer is that as long as the motor oil you choose says that it is formulated for the Dexos 1 spec you are covered even if the manufacturer has not purchased the right to use the Dexos 1 approved symbol (paid GM’s licensing fee)

Dan Peterson, Amsoil Inc Vice President of Technical Development stated in a recent interview that while each of the specifications outperforms the other in some certain areas that Amsoil has formulated its full synthetic motor oils to exceed the requirements of API SN, ILSAC GF-5 and GM Dexos 1 in all areas.

Currently Amsoil OE and XL, 5W/30 full synthetic motor oils meet and exceed Dexos 1 requirements and Amsoil has plans for other such products

I hear you on that, but while under warranty, you do take that chance. I hear horror stories all the time of Chevy dealers voiding warranty for just about anything they can. Not sure I would take that chance not using Dexos oil while under warranty. I'm a service advisor myself, but not at a Chevy or Ford dealer. Luckily, I'm friends with the Chevy dealer service manager where I go. The manufacturer reserves the right to deny coverage if you don't follow their requirements, after all, they are paying for the repair.

Agree, and while paying North of 60K for a car some over 70K I can't see wanting to save 15.00 or even 50.00 makes any sense.

This is what baffles me, we spend all this money on these high performance cars and a bunch of people are worried about saving $30-$40 per oil change... Really???

If the oil change hurts your pocketbook that much then you very likely can't afford the car in the first place...
