So I turned on my car to move it today and there is a thin white smoke coming from the engine bay. When you turn the car off, the smoke gets alot worse. The only things that I have done recently to the car were, change the oil to Royal Purple 5w30 and a Fram Sure Grip filter, and I sprayed SeaFoam penetrating lube on the bolts for the exhaust and cats in a failed attempt to get them loose. I checked all of the vitals and the oil pressure, temp, and everything else checks out ok. I took it for a short drive, to see if I noticed anything there, but it drove fine, actually, a little better since I put the Royal Purple in. I am hoping that it is just the penetrating lube burning off of the exhaust pipes and the cats, but I didn't notice any smoke coming from under the car. To be more specific the smoke is coming from behind the engine by the MAF and that area, on both sides of the plenum. I know that the top bolts for the cats are right under there, so thats why I am hoping that its the penetrating lube. Any suggestions?

 

Probably the penetrating lube burning off your headers/cats.

 

You are saying that your car drives better because you put different oil in?

I call BS.


BTW you are getting smoke because you sprayed lubricant on the Cats, which get very hot.

 

Yeah the smoke went away after a longer drive so it was the penetrating lube burning off. And yes my car does drive better with the Royal Purple motor oil. It is barely noticeable, but it does. Royal Purple has been dyno proven to free up more horsepower. Check it out, www.royalpurple.com

 

That smells like snake oil. You should also install a grounding kit...

 

Mobil 1,Castrol synthetic oils are the best. Cost me $19 for 5 quarts of Mobil1 at Walmart. How much is Royal purple?

 

To tell you the truth, I don't know. They co-sponsor my car so I get it really cheap. I used to use Mobil 1 synthetic as well, but I like Royal Purple better. It may be all in my head, but I swear that I feel a difference.
