How do you keep your engine black black?

Mine is turning a greyish colour, but would like to see it black again...

 

Go to the dealer and get the S100 engine detailer spray that stuff is MAGIC! Makes it look brand spanking new

 

+1 on the S100 - just make sure you get the right stuff. There are a bunch of S100 products... you want the Engine Brightener. Another option is Adam's Undercarriage Spray. It's not meant for the purpose, but it holds up to high temps and works well.

 

My next test is the S100. I have the Pig Spit right now and while it does work, I'm not impressed by the overspray. The S100 has an 'applicator stick' and you can control the spray. Pig Spit also doesn't do that great of a job in my trials.

 

I use Pig Spit and am very pleased with the results.

 

+3 on s100 its the best ive found

 

Make that +4. S100 works great. Makes the engine look like new.

 

How long does the S100 engine brightner last between applications?

 

I use SIMPLE GREEN on my motor, still looks like brand new!

 

hmph... I just use a rattle can...
