Has anyone put Royal Purple oil in their suoer charged engines or transmissions?

Royal Purple is being prosecuted by the FTC (Federal Trade Commission in the US), and their counterparts in Canada for false claims.

Royal Purple, in fact ALL of their products are simply colored mineral oil. Literally. It'* a scam.

i thought yellow made you go faster and purple just made you a queer

True only in children'* television with little space creatures.

HAHA I knew that stuff was b*******. This is why I use mobil 1 Synthetic.

You and me both.

On both my cars, the Malibu AND the bonneville.

not me i use mobil clean 5000. im so afraid to go 6000+ on oil cuz with our intake problems the fist sign will be antifreeze in the oil and i think chainging the oil is a way of seeing how ur engine is acting and how healthy it is. i change the every 3000 just make sure and to keep the engine and me happy.

If I get more than 100 miles past my 3000 mi oil change,I'll leave work early to get it done. Receipts help w/ the warranty if needed

I use Mobil 1 also.

I have been told not to use it in an engine that has been used with conventional oil.... wrong..

I have been told it is worthless, and ruins engines because it is no better than conventional...just more expensive........ wrong

I have heard people who love it, and those who've never tried it, but are too cheap to pay the price, and therefore complain about it.

I have seen my cars engines seem to get better milage, and even a nicer feel, and smoother running since Mobil 1.

I drive around 25,000+ miles in a year, so, Mobil 1 makes sense for oil changes alone.

Here is alink to a site that did a nice test and review on Mobil 1 , and this was before Mobil rated it at 15,000 miles:: http://neptune.spacebears.com/cars/stories/mobil1.html

Keep in mind, you should change the oil filter every 3000-6000 miles, and always check and top off the Mobil 1 oil. These are important to long life.

One more thing that is suggested by some folks, and this might be different with specific engines. I was told to go one step higher in thickness for some engines, as Mobil 1 is slightly thinner than conventional, especially after it breaks down....and it is also recomended for high mile engines. I usually use what is called for. My Caprice, however, calls for 5w-30, but this time I used 10w-30, and the engine feels much better.
