Anyone test Renegade fuel ?

[Michael Beard]

VP has a high pop-off rate (ie., unstable). I've had Sunoco laying around from one year to the next with no issues.

I think many of the 'new' names in the fuel business are offshoots from when the Torco empire crashed. I found Torco to be very similar to Sunoco. Good fuel, and stable.

Remember when testing different fuels you may need to change your jetting. Different fuels can have different sized fuel molecules, changing your mixture.

After changing the tune up, mine likes C11. I have never had a problem with fuel check. Even after sitting in plastic fuel jugs for the winter.

Ed, What is your routine when storing the car for a few weeks between races?
Was told with VP it is wise to fog the engine with Marvel Mystery Oil. This involves changing to old plugs for the fog down. At the next race restart with old plugs when MMO burns off install good plugs.
I run a fuel injected car also and wonder about the caustic chemicals in VP.

Thanks

Frank, I think fogging it is a good idea with any fuel. I've never had any problems with plug either. Mine clean right up. Maybe I don't fog mine as heavy?

This is new to me personally. have always run Sunoco with no problem until recently. My local supplier has handling issues which bit me @ E-Town. Along with the possible closure of the PA refinery that has been making the race fuel.
Ran VP C-12 the end of last season. The exhaust valves were really beat up. Was told that is an issue with VP. Need to fog the engine when stored for more than a few days. The funny thing is that some racers who do not fog their engines make some of the best runs before the freshen up that exposed the beat up valve. So go figure but I would rather the engine come apart clean.

Mike perhaps you missed my post/question...

But are they a refiner/are they producing the fuel or buying the fuel and reselling and if not a refiner who is making the fuel they sell?

Never heard of them until a few months ago.

As for Torco, used it one time and never again. Leaked past my carb gaskets and stained my intake manifold. Sunoco nor VP have ever done that.

No , i didn't miss your post , i just wasn't sure what question you wanted answered .
I can't tell you too much about your Torco problem , could have been an issue with the brand of gasket you were using . Staining comes from the dye used in race fuels to distinguish one from another . Some companies use more dye than others , but all race fuels can and do stain . Race engine builders have long used the traces of dye to follow race fuel through the manifold and head ports to get an idea of flow .

Renegade hasn't done nearly as much advertising over the years as some companies . Doesn't mean they aren't as good or even better . Just means they spend their money on other things like R&D . They have recently stepped up the marketing , that's probably why you starting hearing more about them .

ALL race gasolines are refined , there's no other way to make race gasoline . They start with base stock . And then EVERY race fuel company buys compounds and chemicals from a number of sources to add to the base stock to create their own version of the best . And that's where the differences between race fuel brands come into play . Race gas formulas can be manipulated to make them do a wide variety of things . You can blend for max power , or you can blend for max torque . Or you can blend for mileage ( think NASCAR ) . And of course you can blend in certain compounds and chemicals to work with nitrous or supercharging/turbocharging . In F1 , race gasoline is also blended specifically for weight , every pound saved is an advantage .

Michael is correct as usual . Changing to different brands of race gas , even the same octane rating , will sometimes require a jet change and always requires checking the float levels . The jet change is only required if the specific gravity ( density ) of the fuels differs by more than 2% . For instance going from .710 SG to .715 SG would require no jet change . However , going from .710 SG to .721 ( or the other way around ) would probably require a change in jetting of 1 step . The plug readings will be your guide .And any change at all in specific gravity means it would be a good idea to check the float levels in the carb (s) .
