Sure it works for factory Corvettes, but what kind of factory Corvette engine cranks out 750HP?

I'd say talk to the engine builder because custom built engines often have different bearing clearances than OE spec engines.

Anyway, I know plenty of guys use Mobil 1 in their built race engines, but usually the 15w50 viscosity.


The ZR1 is factory 638HP and comes with Mobil 1 5w30 in the sump.........

638 is significantly less than 750.

That, and the 638 is taken at the crank. Is the 750 at the crank, or at the rear wheels?

That in mind... How much can be gained from ZR1 without raising the boost pressure or modifying the internals?

Were talking minutae and diminishing returns here IRT the HP numbers at this level including they are both using F/I. This isnt some stock C6 (not that they are anything to sneeze at!) its a factory BOOSTED Vette so Id say that M1 would be fine (GM obviously thinks so) for the OP's app, especially given his stated OCI.

In the OP he gives RWHP numbers. Factory boosted engines usually respond better to mods than do N/A engines. The C6 Z06 can get quite a nice bump from just intake/tune, so I am going to asssume that the ZR1 would be able to achieve 650+ whp easily with I/H/E + tune.

What does your engine builder recommend? Why is it moderately driven - you want to trade for my Yaris? This way you can beat on it and no one will notice

Ah my friend, you have obviously never driven anything with this kind of power on the street, or, you would not have alluded my driving habits..........
Ive owned a 350 HP V8 Vega, a 428 CJ 69 Fairlane 5000 FB, a built 396 '67 Chevelle and a 65 401 Buick wildcat, a 93 Lincoln Mk Viii, but you are correct, Nothing with high torque above 4000 RPM. Not Streetable for sure. So, Why so much HP that cant be used? do you track the car, and just street it periodically?


Not to hijack the thread, but tell us more about these cars, ARCO.....

That's an easy question.

Amsoil 15w-50 racing oil.

The same thing I use in my 850 hp 555 ci stroker.

A Fantastic oil that really holds up well.

Exactly. His sig shows 650RWHP. This isn't a far cry from the ZR1's numbers, and the ZR1 comes with a factory warranty.

About 100-120 rwhp more. Still, I don't think I would run Mobil 1 5w30 if I had a ZR1. I'd be looking for something more robust.

Meh, my buddy Paul ran Mobil 1 5w30 in his TT Termi making 750 to the tires

Mobil 1 racing oil 0w-30.

Just another option. Lot of choices available. All would work well. Amsoil Dominator would be another good choice. Forgot about those oils.

My buddy ran Royal Purple 5W-20 in his 700 rwhp Whipple 3.4 03 Cobra...until I talked him out of it.

Mobil 1 5w30 just doesn't impress me for high demand applications. Meh to a 3.09 HTHS in a 700 rwhp car.

 

[Steve S]

What % of the max output do/can you use? How long can you hold the pedal to the metal? Long enough to get the oil hot or get thrown in jail? How does the engine make the increased Hp? It would be fun to See how the oil is holding up via used oil analysis.

I get tired of the comments of how M1 comes factory. So what? There's lot more expensive cars that call for Castrol from the factory..

It's just a sponsor/money thing.

 

[buster]

It's also a performance "thing". Manufacturers of high performance engines won't use oils that could potentially cause engine damage.

So, you are telling me the millions of miles of testing done by manufacturers, including extensive tear-down testing is completely irrelevant?

If Castrol makes a specific oil for BMW, I would not doubt the performance of that oil for a minute. It has obviously been extensively tested by BMW for that application.

Same with Mobil 1 0w40 for Porsche.

Yeah, you can guess and chuck whatever you want in the sump if that is your prerogative. But there is something to be said for using a fluid that is KNOWN to be a good choice for the application and has millions of dollars in R&D, millions of miles of testing, and extensive performance monitoring to its name.

Amsoil RD30 10w30

 

[JohnBrowning]

Redline 10W40,5W40 Mobil 1 15W50, HM 10W40, Rotella T Synthetic 5w40 would all be first choices. I am gu3essing this car does not see winter streets. You can try Mobil 1 0W40 and see how it does. It is used in some very power AMG's but AMG builds an engine with materials that are very different then what GM use's!Give the Mobil 1 0W40 a try or Redline 0W40 it would be interesting to see inthis type of HP Detroit Iron to be honest.Amsoil makes a 0W40 as well!

 

[buster]

AMSOIL Signature Series?

 

[AzFireGuy79]

I have used Redline 10w-40 in a 1000+ HP 96 SS Camaro with great results. If it were me there would be only two oils to consider here. Redline or Motul. Mobil 1 is a great oil but not in this application. GO for a group V with lots of ZDDP.

On a side note how do you like your ProCharger? I had one on my camaro before I decided to get crazy with a custom PTK turbo system. Both have their merits but im loving the turbo power.

 

[Jaymus]

Well, of course Supertech won't come factory in a high performance or high dollar app.

But GM always chooses Mobil 1. It seems like BMW, Bentley, maybe Mercedes or Royals Royce call for Castrol.

I think either oil would do just fine in either brand, assuming you used the correct weight.

I really think a lot of it is hype. I'm not saying Mobil 1 is a bad product. I'm just saying... just because an expensive car calls for it doesn't mean there isn't a better oil out there for it. A little more than we know about goes on behind closed doors at business meetings.

-Mercedes uses Mobil 1
-Porsche uses Mobil 1
-Chrysler uses Mobil 1
-GM uses Mobil 1
-Honda uses Mobil 1
-Aston Martin uses Mobil 1
-Bristol uses Mobil 1
-Bentley uses Mobil 1
-Daewoo uses Mobil 1
-Mitsubishi uses Mobil 1
-Nissan uses Mobil 1 (GT-R)
-Opel uses Mobil 1
-Saab uses Mobil 1
-Vauxhall uses Mobil 1

-BMW uses Castrol
-Rolls Royce (owned by BMW) uses Castrol
-Bentley had been supplied by BMW until Volkswagen bought them. They probably used Castrol during that time. They now use Mobil 1.

It is not a small list of cars that come with M1 in the sump. The list is HUGE.
