Mobil 1 0w40 Dexos 2

And a lot has changed since then too. They did claim 25k back then, but there is nowhere on Mobil 1's website right now that shows those claims anymore. Tell you what Joe, you think you know better than the GM engineers? Change your oil every 25k, I'll follow my oil life monitor (like smart people do) and we'll see who has better results. I'd be very surprised if your LT1 makes it to 100k with only 4 oil changes. (heck, I'd be surprised if it makes it that long running 87 octane in the heat of Texas for that matter, another one of your foolish moves)

The manual clearly states that 93 octane is recommended. It also clearly states that you need to follow the oil life monitor. You're doing neither of those two. Who is the fool again?

There you go again making up stuff, PattyGirl! The 2017 Owners Manual clearly states that 87 octane IS RECOMMENDED AND APPROVED!

The 2018 manual says you can use 87 but performance and fuel economy will be reduced, but in BIG BOLD print it says 93 is recommended. So you bought a high horsepower performance car only to cheap out on gas and limit the power potential that it has. Only a complete fool would do that, especially in the hot Texas heat. You really should change your name to Skid Mark Joe.

I just had a complimentary oil change and they used the new 0-40, The service manager found out and said it was only to be used in the 2019 cars as the tolerances changer and then drained the new oil out right away and replaced with 5-30 at no charge. Anyone know if this makes sense as mine is a 2016 Z51.
See attached......

5-30 Mobil 1 is dexos 1 certified like most oil for gasoline engines. The new 0-40 happeneds to meet the dexos 2 spec which is primarily designed for diesels if they can use that weight. So they put it on.

For the LT1 6.2L engine, premium
unleaded gasoline meeting ASTM
specification D4814 with a posted
octane rating of 93 is highly recommended for best performance
and fuel economy. Unleaded
gasoline with an octane rated as low
as 87 can be used. Using unleaded
gasoline rated below 93 octane,
however, will lead to reduced
acceleration and fuel economy.
If knocking occurs, use a gasoline
rated at 93 octane as soon as
possible, otherwise, the engine
could be damaged.

So they don't recommend the 87 at all, in fact the 93 is HIGHLY RECOMMENDED! But you clearly can't read, you prove that every day on here. And only a complete ******* moron would buy a 460hp car only to have a good chunk of hp taken away by running cheap shitty gas. But then again you're not the sharpest knife in the drawer are you? We keep proving you wrong at every turn, just give up Skid Mark.

This is exactly what it says: I'll type slowly so you might grasp it.
87 octane is specifically recommended for the
2017 LT1.
English is probably difficult for you. Good Luck!

Mobil's own technical bulletins advised with proper filtration, their full synthetic oil is good to 25K, miles. 15K is nothing. 7,500 miles is 100% arbitrary. Your 1 year life of synthetic claim is complete BS. If you're not too terribly busy seeking your free oil changes, you might learn something new for a change. Mobil might claim your guessing is "retarded."

If you want to talk about oil, you're obviously way behind the learning curve. Mobil 1's capabilities are way over your head from your guessing here.

Second, here is one link explaining fuel dilution in direct injection and there are many more if you google it

Does anyone know if this dexos 2 is the design to use calcium instead of sodium to reduce knock potential in the DI motor? I was talking to my mechanic regarding knock I experienced on my dyno run last month and he was explaining that believe it or not it can come from the sodium formula in the detergent in the oil of dexos 1 oil. He recommended Driven DI oil. No I did not dyno at his shop. He said GM was supposed to come out with a similar formulation for oil going forward for that reason. I am wondering if this is it.

Btw for "proper filtering" arent you going to replace the filter sooner that 25k miles so you have to change the oil anyway? Please tell me you are not suggesting changing the filter only at 25k also.
