VP's Ultimate 4
What ever you guys do don't put this crap in you 4-stroke engine. It eats up your piston sleeve and piston after a few short hours of run time.
I know of 4 cases of this crap damaging engines, and one is mine when I was a 730 12.5:1 using the fuel..[img]i/expressions/face-icon-small-disgusted.gif[/img] |

Several people I know run this...I will pass along the message. Bob told me not to run it in my high compression motor back in summer...glad I listened and stayed away from it.
Thanks for the info Ernie. |

Thanks for the heads up Ernie i was about to try some of this in my raptor with a new 12.5:1 piston and it sounds like that would be bad news.What is the reason for the damage to the piston that you described?

Is it not designed to make the motor run lean???

I would like to know what is causing this damage? I know that it is oxygenated, but I thought you were supposed to jet up when running it? Did you guys not jet up? Is the Ultimate 4 the only fuel doing this, or is it all oxygenated gases?

Originally posted by: 86LT250RFatty can someone fill me in on what VP ultimate 4 is? U4 Used in stock and modified 4-stroke applications, as well as stock 2-strokes. Makes up to 6% more power than pump gas and any basic nonoxygenated racing fuel. Passes fuel rules for AMA amateur racing and is also perfect for club level racing, CCS, WERA and AFM. • Color: Clear • Motor Octane: 92 • Specific Gravity: .718 at 60° F |

This stuff is only 92 motor octane. With a 12.5 or more compression and an Ox fuel, things are going to get ugly quickly. Couple that with no rejetting and your going to detonate your motor to death very quickly.
Good fuel, just have to know when and how to use it. |
