Default WD 40 = Performance Increase?

I know WD 40 is just a lubricant that keeps away moisture and aids in smoother functioning of mechanical parts BUT the other day I sprayed the engine bay of my Sswift VXI with some WD40 and wolla engine seems to performe better. Now I dont think this is Placbo as I was not expecting anything of that sort to happen. It was just a humble attempt to make the in hood look cleaner. Fellows any similar experiences!

You cant be serious. How would spraying WD40 on the engine improve performance in any way???? We regularly get engine bays cleaned here with a WD40 wash - but thats for aesthetics and not for performance!

It IS placebo. Unless you nudged something inside while doing it and thats making some difference

You sprayed a moisture remover randomly inside your car's hood and got increased performance?
Don't want to be down on you but thats not technically possible.

Your hood goes up & down much smoother now that the supporting rods are lubricated - now that I will believe.

Nudged what! There is no carburettor in this engine - so the mixture cannot be adjusted by nudging a screw.

Caution: Ingesting/inhaling WD40 can lead to delusions!

Talking Yeah, I understand!

Got it! It's WD40 Raptor!
It spins at 15,000 RPM and how much more faster do you want to go???
Made by one of the best performance oriented product maker in the world. I love their products! Western Digital. They are one of the best man!

But, er..... How did you get it in spray mode??? I've only seen them in PATA/SATA/SCSI interfaces and sometimes it works as RAID too.
Spray??? umm umm! Never heard about it. That too in the engine bay!!! That would be crazy!

Are you sure you are running the stock OS or have you shifted to some aftermarket ones???
(No offense, just a bit of you know.....)

I've seen mechanics test to see if the gasket has failed by spraying WD-40 on the head when the engine is running.

The rpm goes up because the wd-40 is sucked into the engine.

Can't see how that can be happening here though. I'm guessing any residue left will evaporate quickly.

WD stands for water displacement. and 40, it took its inventor 40th attempts to create it.

More than quarter of its ingredients are petroleum products. But it increasing performance is beyond by head.

Maybe its like when you bring your car out of a wash after you went mud ploughing with it, you feel it drives great.

Actually i thought the same thing as you originally did. If there truly was an improvement in performance, I dont think its too far fetched to think that maybe a loose plug cable was moved, or a sensor that was not connected properly was moved or a electrical component that was shorting is now insulated (WD40 is an insulator) etc etc

The same way as starting sprays are used (and really help).
You spray some on the air filter and the car which was having trouble starting now starts with ease.

Though i agree with you that what comes out of most of these sprays will evaporate easily - but WD40 doesnt evaporate that easily does it?

Anyway, thats just the other side of the coin. Quite likely that it is just a placebo effect

Sorry there, it is not an insulator and, in fact, can be a fire hazard!
WD40 is a 'penetrating oil' and water displacing agent, with mild lubrication property. It is non-conductive and 'cures' electrical shorts by displacing water/conductive impurities (carbon dust etc) from the vicinity.

It is NOT to be sprayed into hot engine bays. Could lead to a mishap!

Default soap

After I wash my vehicle I get performance gains of between 23.709 and 25.1463 percent as tested on a stationary dynonometer. Now, of course, I do use synthetic soap............
