FANTASTIC!
This product is spectacular! I had a check engine light that kept coming on after I changed spark plugs and coils. The mechanic wanted to replace the catalytic converter. A car friend recommended this - I put this Royal Purple product in the tank, everything was perfect and no problems, no more check engine light, and it breezed through check emissions.

Terrible product
Upon acceleration my car would kick nd buck through the gears and then even out. I was told to put this in my car which I did. The problem became worse such that as I was driving out of my neighborhood the engine went dead and could not start. Had to call a tow and wait 2 hours and now I would have to tow to mechanic. This stuff is junk it will ruin you car don't chance it like I did.

Not sure about this product.
Verified Buyer -
this product very expensive for not to get some resolt. It give you bust with your gas when you first put it in, however, after that, it seem to not have any effect on your gase systems.
