Default WD40 sprayed on your engine

Does anybody know if it's good or not to spray WD40 on your engine??? I remember my dad use to do that on is cars.
He would say "yeah, it's good from preventing the rust, and makes it look good & clean".

It's just a souvenir I had, and it makes me laught a little.
I remember the smoke coming out of his hood when he would start the car

lol. it wouldn't really hurt much....but wd40 is an oil and it will attract dirt. over a long time if u keep on doing it, there will be a film...no idea if u'll ever notice it though.

i pressure wash my ford escapes sometimes. and they run like hell for a day or so, or not at all.

i have never considered getting near my 968 dme with water. so, my engine bay is fowl.

most mechanics will tell you that coating of gook is beneficial to keeping moisture away from many vital parts,

especially your computer.

the dirt caked oil is "good stuff," except for when it comes in contact with anything made of rubber.

I use WD/40 to clean most all of my parts and to keep corrosion from taking its course. I've used it to clean up tar based products, oil, to clean aluminum, rubber, plastics, etc. Works great - keeps things looking new, moisture free, and lubricated.

WD40 evaporates before it attracts dirt

Never use any products with high PD contents like WD-40 on rubber or plastics in the engine bay. The heat will cause a reaction. What looks shiny and new today will be brittle next year. Polymers are the way to go. YMMV

Never had a problem here. Been using it regularly on my DD since I've owned it... which would be 8 years this June and 120,000 miles later.

True story:

When I was younger I worked on commercial fishing boats to earn money to pay for school.

One of my first boats was an all-Croat crew and at the time I spoke almost no croation. Even worse, the crew spoke almost no english.

My first day on crew I was laoding supplies at the dock when a forklift arrived with a full pallet of WD40. I assumed it was to be shared so I only loaded a single case. Captain came by an hour later, saw the pallet, and mimed for me to load the entire thing. Which I did.

I couldn't fathom what we needed a full pallet of WD40 for so I asked the one other crew member who spoke at least a little english. After a few stumbles he finally understood my question: "what do you use all the WD40 on"?

"That?" he said, "Oh. We use that on EVERYTHING"!

And they did. Off the top of my head:

Lubricant
Cleaning solution
Insect repellent
Detangling nets
Keeping glass from fogging
Repelling seagulls
Relieve jellyfish stings
Chumming the water to attract fish
Water repellent

There was even one old guy with arthritis that constantly rubbed it into his joints. WD40 was everything to these guys.

^^I agree with both of you. (Steve and Marc)

I wouldn't get WD near anything made of real rubber. Seals and silicone vacuum lines would be fine though.

And.... I also use the hell out of WD-40 for cleaning parts. It works really well, and when your done, they will be rust free and lubed..... as Marc said.

Also, if you need a quickie wax on your car, mist a rag with wd-40 and wipe down your car. It will shine like it just got a full detail.... even old paint. Then, after the pics have been taken, wash it off at the carwash.

I thought it was a family secret...evidently not...

My grandfather would use WD-40 to attract fish. He would wet down any bait he was using... flys, lures, even worms. It worked amazingly well. He ALWAYS caught fish.

And I will also vouch for it being used as insect repellent. If you don't mind being covered in oil on a hot day, it will keep the bugs away.

The WD stands for water displacement. It helps to get moisture out of where you don't want it. I read something a while back that said a main ingredient was some kind of fish oil....

all you need in life is WD40 and duct tape.

WD40 for things that should move but don't

duct tape for things that shouldn't move but do.
