Is Mobil 1 SUPERCAR developed by Corvette and Mobil the best now for a 4 stroke engine?

Is Mobil 1 SUPERCAR 5W-50 the best engine oil for all four stroke engine engines? The way I understand it since it is a 5W rating it should be great in cold weather or anything south of maybe New York? The 50 rating should mean it is great in hot weather and usages where you’re creating a lot of heat in the engine like road racing, etc.
I get the impression that it is a new formulation and supposed to be the best or at least a top quality product since it’s used in the new Corvette.
Is there materials used in European engines that would make the mobile 5W-50 motor oil not the best choice?
Am I missing anything? What should we know?
Thank you.

Seems to shear not terribly but quite a bit. It's far from the best oil for all engines but it's extremely far from the worst and it's definitely not the best 5w-50 as hpl takes the cake but neither is it a bad 5w-50 either, that's be motorcrafts 5w-50. Engines running in horrid winters would struggle with a 5w-50 unless they had some super wide clearances and called for a 50.

As you probably know oils with a wide viscosity spread use more VII's (viscosity index improvers) to achieve this. They can and do shear. Some of the guys who use such oils in KTM motorcycles with a shared gearbox find that ANY 5W-50 shears quickly in those engines. The same situation may not exist in more pedestrian engines and the oil lasts longer.

There is a company that makes a series of oil with no VII's for just this reason. They can be used in 'tough' conditions without any risk of losing viscosity.

I use M1 15W-50 in my turbocharged race cars, motorcycles and generator engines. Not because it is the absolute world's best oil, but because it is a very high quality oil that holds up very well, does not coke turbochargers, leaves no engine deposits and is available at WalMart in 5 quart jugs. It will handle brutal high temperature use when 5W-30 won't.

We have run into situations where oil temp exceeded 300ºF and oil pressure loss was a problem. We moved up to M1 20W-50 V-Twin oil. Again, WalMart to the rescue. The oil is a spectacular product, with an HTHS over 6, it can handle the heat. One would have to use a specialty oil to match M1's 20W-50 robustness.

No.

Very few people actually need a 50 weight oil. In fact very few will actually benefit from a 40 weight oil for that matter. So no, it’s definitely not the best choice for all 4 stroke engines by any means.

What does hpl stand for? Is hpl a brand and model?
How would a 5w oil be bad in winter is it not good down to about -22F?
Or according to NOAA there is no U.S. Continental state that averages anywhere close to -22°F in the winter.
Not attacking just a honest question using the knowledge I have.
Thank you.

According to Ford, they recommend 5w-50 when I track my MACH 1. Other manufacturers do also as far as I know.
From what I have read and consumed 5W 20 in the lower weight oils are only two meet EPA standards.
The heavier weight oils like 5w-40, 5w50 are better if you’re focus and concern is for your engine longevity!

People run it in BMWs spec'd for 10W60 and have great results. The 5W rating means you get better daily driving characteristics but still have good high temp protection.

I wouldn't worry about the higher VIs. If you are actually tracking the car, chances are you are doing shorter OCIs anyways. A lot of these engines can use 0W20 if you don't drive hard. I think on some of the Mustangs they spec lower viscosity, unless you get the track package, where they say to use higher viscosity, but engine is the same.

The 20 weight oils are just fine for most of the driving public though and even the harder driven cars like my Corvette are just fine using a 5w30 that has a higher HTHS (the oil I use in my Vette has a 3.5 HTHS). For cars that are taken to the track they can often benefit from a 40 or 50 weight oil but the amount of people who actually do that are probably 1 in 5000 drivers at best and likely way less.

I still stand by my firm belief that most people will never have an oil related issue with oils that are in the 3.0 to 3.5 HTHS range. (And gently driven cars like my Civic can get long life out of their engines even with a 0w20)

Yes, 100% agree with you.

HPL is High Performance Lubricants. They blend their own products.

A 5w50 uses Viscosity Index Improvers and may also use Pour Point Depressants. Neither VII's nor PPD's are lubricants in the same way that the base oil is a lubricant. Also, neither VII's nor PPD's are detergents, nor dispersants, nor anti-wear, nor anti-oxidants, nor any of the other beneficial additives that help to fight oxidation or acids. So, I wouldn't say an oil with such a high viscosity spread would be "the best" for "all 4 stroke engines".
