Use of Grease to Lower Drag - Fuel Economy, Hypermiling, EcoModding News and Forum

Alright guys, I have to go to work but I wanted to post ths so for the next 18 hours, you all can think about this

So I was just cleaning a plate, and there waa grease. As in fat. I tried to clean t off of my sink, and my fingers were all gross and geeasy. The water just slid over it, and it took soap and very hot water to get t off.

SO clearly ts woud make a good finish for water, but could ths have any possible benefit for fuel efficieny? As in making the car more smooth?

I am thinking to use it for the front end on my next road teip, instead of painters tape to protect the front end from bugs.

So I don't think t wil do anything, but I jist wanted to toss the idea to you guys. Let me know what you think!

We just had a discussion on boundary layers and how they aren't laminar on cars and how they are rather thick and get even moreso as they go to the back of the vehicle and how all that makes the surface finish not critical.

But yeah, interesting idea for keeping the bugs from sticking.

It might also help with the dead pedestrians piling up on the front of your car.

I suppose you could grease the tyres up and see if the reduction in friction helps any.

Caution: Don't do this.

Was this on the forum? If so, where at?

How would you keep from accumulating a layer of dirt on the car ?
You would have to wash the car more often .

Thanks, markweatherill. Now I've got to clean the coffee off my monitor.

I don't think greasing the nose is a good idea. You're going to collect dirt and bugs. It's going to streak backwards and cleaning it off is going to be a nightmare. Stay with the painter's tape.
