sounds like you are here peddling crap to me, the dyno test doesnt prove anything? a dyno test is different than a real world test? no shit, pro street didnt claim to do / say any of those, they are testing the same car on the same dyno with different oil. dont think that you come on here claiming to "help enlighten us" with some link in your signature to a site is really anything but a flimsy attempt to sell something. go away troll

btw, theres a period in your link to your "authorized amsoil dealer" website, might want to remove it. Doesnt do much good spamming if nobody can get to your site

Not everybody has the facilities to evaluate their own oil nor do most tuner shops.
This test was a test of the top oil manufactures which have already passed all of the above certifications/ requirements by said institutes.

The testing done here is to show a baseline fossil fuel oil test against the best that manufacturers have in their synthetic lineup.
Most tuners recognize all of the names in the given test and like so many that ask, "which oil is better", gives some relevance to how these oils provide better lubrication compared to dino oil.

Most tuners that do race their car will gladly pour out their Mobil1 for that added couple of horses.

Agreed and that is why all of the oils tested met these standards before the dyno tests.
It's not like we formulated our own oil product and tried to compare it to a benchmarked/ standardized product.
This test took top grade oils and tested them against each other to evaluate hp gains on a dyno. That is all.

It's a good comparison for normal folks to understand.

Not knocking your post but I think you got too deep in the scope of the test.
I'm also no expert or been in the field of oil research but having tuned, raced, and mechaniced automobiles for over 28 years, can speak a little bit of the test and what it tried to communicate to the tuner/ racer.

In my studies and employment as an undergraduate mechanical engineer, I've done some studies simiar to this in that they deal with very very small variables (example; piston rings). Similar to this test, those tests yeilded variances in dyno results which don't even go outside the accuracy range for the dynomometer equiptment itself. Obviously you achieved a fairly substantial increase away from Penzoil (which is recycled oil) once you were into synthetics, but I would guess your accuracy range to be about +or- 2 hp based on equiptment and far more than that caused by variables.

For an actual comparison, down to the 1.7 horsepower you are disagreeing with, there would need to be a severe revision and reduction of the many uncontrollable variables in this experiment. These variables include but are far from limited to: air temperature, wear of engine components, wear of driveline components, residual lubricant from the last batch (everytime you change your oil, there's still some recycled, stuck to your engine), heat in other areas of the vehicle (transmission, any bearings), even fuel is within a quality range; unless you can verify that all of your unleaded is from the same tanker, you have then a large (in relativity to 1.7 horsepower) variable.

I'm definitely NOT saying that this is not a worthwhile experiment, especially since the penzoil gave you 224 hp and the lowest of the synthetics gave you 231 hp. That's quite a jump and I'm actually surprized, this assuming your variables are even kind of close. What reinforces this is that Penzoil was the lowest, just like we thought it would be. I just don't think that you could conclude that AMSOIL is a worse product than Royal Purple because their results were 5 hp different. A friend of mine with an AWD recently went from dinosaur oil to 100% Royal Purple Synthetic (out of personal choice and discount) in his differentials, transmission, and engine. From this event, I would testify that this magnitude of fluid replacement resulted in noticable increases in horsepower and capability. Unfortunately, this was change was not measured on a dynomometer.

There is undeniable advantages to synthetic lubricants as far as performance and engine longevity. The only selling point on synthetic engine oil I don't buy is the one that endorses a longer period between oil changes. I can't rationalize leaving my engine oil in longer than 3000 miles because, even if the oil itself does not "break down" there is still stagnant polution in the oil, dirt that can't be removed with a WIX filter.

But which one is best? I can't tell you. Isn't Mobil 1 the company that just had a major violation with some of their oil falling outside the quality mandations standarized for labeled production? There you go, there's variances in the oil itself.

I'm a member of the Society of Automobile Engineers, those who don't use chassis dyno tests to compare engine oil.

That being said, I still use Valvoline dinosaur oil in all of my dailies (max 230 hp), and AMSOIL in the performance vehicles that I deal with.

first time I ever read on an oil test, so thank you prostreet and all the positive member diferent opinions

cavalierkid

so from what ive seen royal purple did the best?


just wondering because i use the royal purple 5w-30

and if it adds alittle more horsepower thats just a bonus because i think they have a great product ive used it since i got my car (except once i was almost broke and put quaker state synthetic in)


NO I DONT WORK FOR ROYAL PURPLE AND I DONT SELL IT but i could use the money if someone wants to give me $10 a quart i'll go buy the $6 quarts and give them to ya

TrappedDarkness

...... why would i give you $10 for something that would cost me $6??

cavalierkid

it was a joke ya know haha lol trying to be funny

Icepic

wow penzoil is recycled oil huh, never knew that. I use castrol full synthetic, what can be said about that, good or bad?

Joined just to say that I am anxiously awaiting the results of redline... been considering switching from mobile 1 to redline...

I remember watching some show on the SpeedChannel. They did a dyno on a brand new corvette (back in 05) and then they changed all of the fluids to Royal Purple because Royal Purple says they add 5-10hp with their fluids. The corvette got 7hp more. Pretty interesting stuff. I've torn down the engine in my old Eclipse that I ran Royal Purple in. Pretty clean on the inside and that's one of the things they advertise also.

will this ever be updated again?

projectX

hummm...ive been considering a change from moble-1 to royal..ive herd good things about the purple stuff...are the test's done..and screw that oil guy..go friggin drill your self in the ass man...and take your link with ya...friggin trogladite merchant!....

ps...please conclude this test for us pso..and thanks in advance for the legg work

GSRTURBO

bump for update!
