IWSTI Addict since: Nov 2007 Trader Rating: (0)  |  Royal Purple Horse power gains?? Does oil really provided more horse power? Can someone explain how much horse power royal purple can offers and what makes it better than the rest? This ad is not endorsed by this member. Please register or login to hide this ad. |

IWSTI Addict since: Dec 2006 Trader Rating: (1) | Re: Royal Purple Horse power gains?? If you gained three to five HP from Royal purple it would be due to reduced friction. If you had enough bearing/piston to cylinder wall friction to eliminated to free up 3-5 HP you would be making A TON of heat in the engine and killing bearings to reach said delta. |

IWSTI Addict since: Apr 2007 Trader Rating: (0)  | Re: Royal Purple Horse power gains?? One of the tuner mags just did a test on like four oils... Royal Purple being one. It gained like 2.4WHP. I think the car was a S13 or something... was a few months ago. Enos beat it though... I use RP in my ride |

IWSTI Addict since: May 2008 Trader Rating: (1) | Re: Royal Purple Horse power gains?? Wow really? I've used it a couple times in my car and it does seems to burn off quickly. I've always heard thats its quality stuff but maybe i'll have to switch to something different.. -shamy. |

IWSTI Addict since: Apr 2006 Trader Rating: (9) | Re: Royal Purple Horse power gains?? synthetic might make a slight difference in horse power but if you see ANY gains at all they wont be more than 1 or maybe 2 AT MOST. but you could probably attribute those gains more to it being 5 degrees cooler in the room than the oil |

Let me say this. It's very common in racing for teams to use a different (lighter) oil for qualifying and then put some heavier oil in the engine for the race. It really does add some horsepower. I have also read several tests where small gains were shown on a dyno just by switching to a different oil. Anyway, it's possible, not just marketing. Not like anyone is gonna feel 3 horsepower... | |

IWSTI Addict since: Nov 2004 Trader Rating: (0) | Re: Royal Purple Horse power gains?? Royal Purple shears very quickly, which can cause bearing wear and damage, especially if you started with 5w30. This ad is not endorsed by this member. Please register or login to hide this ad. |
