It's the same exact stuff that Walmart sells. Cheaper at Walmart.

That test is just about useless. Even as the text states: All testing must be repeated several time to prove results. This one was done once in somebody's garage....
I wouldn't care how cheap it is at Walmart or any other store. I'll stick with the established brands...

When Chevy starts putting Amazon oil in Corvettes at the factory then I'll stop using Mobil 1

The Mobil 1 that was the original fill back in the C5-era is not the same Mobil 1 sold today. EPA mandated a reduction in Zinc levels (and other additives I believe) a few years ago to meet clean air standards...the reason you shouldn't run modern oil in vintage muscle cars without adding an additive like Lucas.

Not trying to start an oil holy war here but there are much better choices out there for the Corvette than Mobil 1 (no...not Amazon oil).

I will continue to run Amsoil, not Amazonoill.....

Which Mobil 1 did you have in mind? Zinc levels are all over the place:

This is not a lab test, it doesn't give you _most_ of the important figures.

Go with what your dealer recommends, or what your race shop recommends, or what your engine builder recommends, and don't overthink it.

Some insider stuff. When Dave Hill wanted to build the first benchmarked 200,000 mile motor . there were lots of discussion on how to get there. there were many top tier ideas, One was make it light, avoid the gas guzzler tax.. Keep it within budget and deliver it on time. Raising the run temp was revolutionary but in testing, hotter is better for longevity. Not so good for Hp. Running a hotter motor temperature was challenging, since the cooling design was a bottom breather. WE knew that pulling air from a black top surface that can see 140F on a Hot 95+ F Georgia asphalt highway in the summer did not deliver a lot of heat transfer to cool this motor.

OIl is not just lubricity, its oil and an additive package. Mobil developed a high temp additive specific to the LS1 in a Y body. This additive will help stabilize the integrity of the additives under the excessive design of the run temp. The reason GM says to change the oil in a C5 every year is because of the heat saturation and the breakdown of the additive package that protects the motor. The run temp of an LSX in a C5 is unconventional . Its the reason we could certify 200,000 miles on this motor, and when torn down we found every spec to be within tolerance.. The C5 was way ahead of its time in 1997.
I know people will say they screwed up a lot of things in the design.. The reason for this is Time and budget. From a clean sheet of paper it took two years to design the C5. Its a daunting task.

Buys $75,000 car. Saves $12 on oil change.

I've been very happy with Mobil 1.

Evil-Twin

I may have overfilled

Do you have the full designation of the current Mobil 1 package? Does not seems to be available here with GM4718M standard. It is not that the temperature is very high here anyway...but...will have to change the oil anyway one day.
thx.thank you in advance.

Google....Bob the oil guy......everything that you should know.

Amsoil.........NEVER

They are a pyramid marketing scheme company................not an oil company.

Evil-Twin

Bob never mentions the very unique run temperature designed into the LSX in a Y body because it is very unique. Its the only car out there that its normal run temp is in the 190F to 230F range. Normal.

If you're saying that today's M1 is not as good as the M1 in the late 90s, I don't believe you...

I will still be buying Mobil 1 but curious to find out who makes the Amazon synthetic oil.

See my post above - it's the most detail I've found.
