Decided to do a little test with my dyno ***** street car. Changed the oil and put in Redline 10 wt. racing oil. Tuned the car to a tee. Changed the oil and put in Quaker State 5w/30 full synthetic that I won in the dyno challenge at the Vegas NHRA event. Dynoed again-no changes. Red line is the Redline oil (appropriate) and the yellow line is the Quaker State:


A/F graph:



5.5 ft-lbs of torque and 7.3 hp. I do not recommend this oil for the street, but found the results interesting. Just thought I would share.

Wow, thats a big difference. Just curious- why don't u recommend redline oil for street use?

Also thanks for sharing

 

racing oils don't have any detergents

 

good info

 

Nice, thanks for the info man! Do you think the oil would be ok in a motor that maybe gets 5k on it a year?

I may be changing my oil very soon..

 

i used redline on the street , oil got dirty really really fast.

 

what would be the next best thing in oil compared to redline, but being able to use on the street?

 

All i have to say is... DAMN!
It'd be a good oil to run just at the track. And for dyno whoring.

 

not to bash you. but i dont think your conclusion has been proved definatively.
I mean, If you want to compare viscosity, why didnt you use the same brand oil? and do a back to back to back test where it was oil A then B then back to A to make sure the motor was performing consistent.

Why not try a redline 10wt vs a Quaker state 10wt. if nothing changes in Hp/tq between these 2 oils, you can rule out differences in the brands.

I would like to see a more thought out test. but im interested in seeing a difference in the weights of oil on a race motor. easy hp is easy hp.

 

This was not brand x vs brand y. It simply demonstrates that choice of oil can have an affect on HP. That's it. Same motor, same dyno, same state of tune.

 

but you have to take into account the practices of the manufacturer. This is more an red apples vs florida oranges test rather than a red apples vs green apples test.

 

Perhaps he didn't set out to do a red apples vs green apples test?
He is just sharing the results he got and thanks for doing that. I didn't imagine the difference in power would be that large.

Yes it is. I agree. You are correct. The point is that there is a difference between the apples and the oranges. Choice of oil makes a difference in HP. Simple.

 

The redline racing oil doesnt have any detergents, they do have a multiweight thats good for street use though.

And I agree with you. I just dont think that your test proves or disproves that. If using the same logic you have, why can we not say that redline oil and horsepower have a relationship? I only dispute the conclusion based on this test. Although it has the potential to support your claim, i dont think it, on its own, does that.

 

Oil weights and also oil temps have a big effect on hp.I've done a lot of testing on engine dynos and keeping pulls at the same oil temp is critical.I do a number of pulls to get the temp up before making any other changes.It's easy to see a 6 or 8 hp change between 180 deg and 240 degrees.When nascar was using qualifying engines they were using 0 weight oil and 22 pounds of oil pressure at Daytona.The is no question about an increase in power using light oils.There are limits before reliability drops off though.

And that was somethin that I thought was a myth, never really saw any proof. I remember when Jeff from Importbuilders did a "oil vs. oil" dyno. I think it was a Redline vs. Mobil but I'm not sure. His dyno proved to be no improvement, I dunno, I know you're tight with Jeff B19 so maybe you could link the dyno chart? This is the first dyno that I have seen that shows brand x making more hp than brand z.

That is why I would not recommend the 10 wt racing oil for the street. In the short term, it would be o.k. In a daily driver you are just asking for engine failure. I bet the Nascar guys would not use their qualifying oil for a full 500 mile race

BTW-this is not brand x vs brand z. The oils used are wholly different and it would be a completely unfair comparison.

Nothing was changed except the oil. How does this test not show that oil makes a difference? Please explain. What am I missing?

Nice info ,thx for sharing. Oil viscosity does effect on hp output but remember to pick the right viscosity for the right usage.The lighter they are the better for hp output but engine reliablity is compromise...I use redline 50 wt race oil for road racing honda engine NA powered for durablity issues and longlife engine parts. Just playing it safe rather than gaining few hp then not finishing the race....

 

thanks for taking the time to share the info with everyone. sorry people are hounding your ***** about it.

 

Quick footnote:
The whole oil/HP relationship is not something that I discovered on my own. I was blissfully ignorant. It was suggested to me by Brad (aka MAX_CFM) and Rocket. Thanks guys

this test has too many factors to get the conclusion you are making. If you want to test viscosity (which you are trying to do here), choose the same manufacturer. Again, i said oil does make a difference; in this case, i dont feel this test accomplished anything but to spark peoples interest.

 

Interesting results, I would love to see somebody do more exstensive testing

I think the only conclusion he is making is that oil can make a significant difference.

It's not enough data to say "Run this oil, run this weight, run this etc and you will gain roughly 5whp" but it is enough data to say oil can make a measurable difference.

I would also like to see more testing, X weight vs Y weight, X brand vs Y brand, etc but at least now we know it would be worthwhile to do so.

Previously I am sure most people knew that in theory synthetic oil made more power than non-syn, but probably figured it would be a 1-2hp difference at best. Now that we know it's not (and it might be a larger difference due to the power output and/or build/clearances of this motor) we can research from there.
