Second Dumb Question, dealer and manual say VP U4 fuel only is there anything else I can Run. 50 miles or more one way to get race fuel.

Most 93+ Octane fuels work fine unless you're racing

Thanks, not going to race yet, still need to do break-in and get started.

OOPS didn't notice it was a Destroyer... you can still use 93+ in a pinch, but watch for detonation under hard throttles... find some 100 octane at the local airport

Got you beat.... I started in '78

Long time in EMS
Too Long! 20 years here in sarasota... other time with another agency didn't count for retirement... 5 more :banghead: to go:banghead:

Personally I wouldnt run anything but race fuel in a destroyer. They like the "good stuff" :D

All VP fuels are available in 5- (19 liter), 15- (56 liter), 30- (113 liter) and 54-gallon (204 liter) pails and drums except where noted.

NEW! U4.2TM
The latest generation of our U4 based fuels, this fuel is a direct pour-in replacement for U4 with little to no jetting changes required - +2 main jets and +2 pilot jets at the most. Makes power equivalent to U4 with no sticky residue and a less pungent odor. U4.2 passes AMA amateur fuel rules and is perfect for club level racing, CCS, WERA and AFM. U4.2 makes up to 6% more power than pump gas.
• Color: Blue
• Oxygenated: Yes
• Motor Octane: 102
• Specific Gravity: .784 at 60° F





U4e
Developed for those states that restrict the use of MTBE in fuels. Will work well in the same applications as U4, with comparable power increases.

• Color: Pink
• Oxygenated: Yes
• Motor Octane: 93
• Specific Gravity: .718 at 60° F




In the above which is direct from VP's web site The U4 ranges from 93 to 102 octane..... I stand by what I posted earlier... 93 will run the motor, but may detonate at high throttle openings (load).... AVGAS at 100+ octane would be a good substitute for the VP U4.2 but you probably wouldn't see the same performance. There's a lot of drag racers on this forum who should be a lot more knowledgable than I about substituting fuels.

Sorry Cap, Wasnt saying what you said was wrong. Just IMHO a race engine deserves race fuel not pump gas. In my X I just sold, it only ever ran on VP 103 or VP 109 Race fuel. It certainly helps to have certified quality fuel, removes all doubt :deal:

No offense taken....... its just that he was asking for an alternative fuel, and I was trying to help him....

how do you say??? "No worries mate"???

I run VP C-12 unless you're running AHDRA then you have to run U-4 but it gums up if you leave it in to long. The newer U 4 E doesn't gum up up but mine runs better on C 12.

I wouldn't be comfortable recommending that you use anything but what is recommended!!! You don't want to burn anything up. Pump Gas won't work!!!

Any one had experiance with Sunoco Racing Fuels, Dealer about 20 miles from house. VP going to have to be ordered and shipped UPS

I use also the VP U4 fuell and tested some differend fuells also like VP C25 and from the German shell v-power 100oct bud there s a difference between the country`s here in Europ. (only the German is powerful).
and what i prefair is U4 bud hard to get here .
you can find some fuel map on the V&H site for c25.
