It's mostly a load of crap. You want to make more power you need to run a lighter weight lubes.
Putting one of Royoal Purple's race weights in a Honda i4 VS some cheap crap of specified viscosity maked around 10 peak horsepower. Anything else is going to be neglidgable power wise. You can fart in an intake and make more power than the difference between the greatest oils off all time VS the cheapest crap you can find. As long as both are new & the same viscosity.
It's not the "super new oil" that makes the power difference. It's the super thin oil viscosity.
Same goes for everything. Thiner oils get out of the way & take less motion to get them oil of the way faster than thick oils do.
Ya... That video they even say "Tuning up the ignition" hah.



Think about this... They made less than 4whp by using some of the best synthetic fluids lubricating everythey they could, and giving the engine a mild tune-up.

Just put good synthetic fluids in everything that are the specified type & weight.

My ES's 3vz-fe has all new seals. I'm currently running 5 quarts of mobil 1 synthetic 3 are 5w-30, 2 are 5w-20.

Thanks Dave...I'll stick with mobil1 for my lsd

I put up a post earlier in the year about that product. https://www.clublexus.com/forums/sho...highlight=EXP4

I put Redline in my 3.76 LSD and it seemed quicker than before the change.

9HP from lube in a rear diff, that's the same thing as removing 6750 Watts (9HP equals 9x 750 Watts). That's not possible, the GS's rear end doesn't consume 9HP no matter what kind of lube is in it (except maybe sand). If the Lexus rear diff used 9HP, it would burn itself up in a few miles. The Lexus rear diff consumes ~1-2HP, if RP lubes could add 9HP, then it's making HP from nothing. That's against the law (of physics, 2nd Law of Theromdynamics if I remember right).

The 9HP figure comes from a Top Fuel dragster running 4.5 seconds in the 1/4 mile with over 8000HP (9HP is probably on the high side, after all, it is an ad).

Watch out for the SOTP dyno, it always lines up with the money spend on the mod.

The state of motion of an object is maintained as long as the object is not acted upon by an unbalanced force. All objects resist changes in their state of motion - they tend to "keep on doing what they're doing." The videos are of different vehicles. Different vehicles will yeild different results.

Consevation of energy, you can't make energy from nothing. The diff only consumes 2HP as drag on the power train, Royal Purple can't save 9HP on a Lexus, the drag is only 2HP.

Guess the Mustang and Camaro have a better stock rear end.

Vette Boy

If the total power loss is ~2HP, the most I'd expect a lube to help out would be ~10% or 0.2HP. Even that isn't likely if the old lube is in reasonable shape. Compared to other lubes, I doubt there's any measuable difference in a 300HP Lexus/Camero or Vette for that matter.

If it sounds too good to be true (9HP for $20), it probably is too good to be true. Save your money for a proven power adder, the Vortex, or maybe some of those gas mileage magnets

I believe the nine horses come from a combination of synthetic tranny, engine and diff fluid as depicted in the camaro video. If you look at the video with the mustang, all they did was change out the diff fluid and gained a total of 3 horses.

Vette Boy

Look, I don't like to see people scammed. The claim that changing out rear diff fluid in a Mustang rear end will lower losses by 3HP is :BS:. The variation from different dyno runs can be 3HP.

There's nothing wrong with their product, and it isn't any better than Redline, Mobil1 or any other good synth.

If Royal Purple is claiming they can save 3HP by swapping diff fluid, shame on them. Makes me wonder if they really know what they're doing. It's easy to make a good lube that runs down the strip once on a sunny day and then gets changed. I need one that works from -20*F to 120*F for 20K miles. I'll stick to Mobil1 for that.

I hear that.. Thats why I wanted feed back.... I can truly say I feel a difference by changing my engine(Amsoil), tranny(Amsoil), and diff(Royal Purple) to synthetic. I never dyno'd the car, but it feels smoother and quicker off the line than the dino oil. Would have been great if someone did a before and ater with a gs4.

Vetteboy, I'm pretty curious where the "2hp" figure comes from...... Care to share?

An average car can easily lose 15% in powertrain losses. Some basic math would tell you that we should be losing more than 2hp in the rear-end.

Vette Boy

If you think I'm wrong, show me your math. Make the total loss of the diff as high as you see fit, just remember, all the losses are friction, it's just heat. The rear diff doesn't have any cooler and has to dissipate the heat through the case without getting so hot the lube boils and the bearing and gears seize. How many watts of heat do you think is being dissipated? How much better is RP compared to dyno oil, 10%, 50% 100%?

BTW, 750W = ~1HP. Every 2HPs of loss is the same as a 1500W heater in the rear diff. Make the loss 5HP, that's 3750W of heat in the rear diff. Imagine a space heater the size of the GS rear diff with ~4kW of heat in it. How long will that rear diff last before it just burns up?
