Yeh Baby,Their language makes me randy 😮
I can’t even type it let alone say it. Perhaps we can pick on them this winter when things site get really slow.
The one big variable in spec fuel is that spec oil is also required. As Brad will attest to at the last CSC race at IMI, he did a sample on 3 different oils mixed with the same fuel and all three came up with different readings. You cannot have a spec fuel without a spec OIL. I would LOVE to see a spec fuel and oil at the races, but it MUST meet manufacturers specifications for the engines also. Making someone race with a fuel that is outside of the specs of the engine is not right also. The biggest turnout of motors in TAG is Rotax yet most tracks don’t stock the correct fuel for that. Telling everyone to drive to BigT, which for some of us is pretty tough, doesn’t work either. At the last CSC IMI race I bought some 93 octane pump gas because that is what I was told to do by the race official. And you know what, Dane’s times were the same with the pump 93 as they were with the track 100.
Either make a spec, stick to the spec, supply the spec fuel and oil or don’t do anything.

Be aware, that VP MS93 may not pass if the calibration sample was something like VP100. There is a + and a – spec on the fuel test. So just by buying VP MS93 for your engine does not mean your legal.
To correctly do this for TAG at least, you would need multiple control samples, all mixed at different oil ratios for the different engines per the manufacture specifications. And this would need to be done with a spec fuel and a spec oil.
Hey, I know what. Let’s institute a Parc Ferme at the CSC races, bring in Big T fuels and oils and the problem would be solved. 😆

What does everyone think of the redline synthetic 2-stroke oil? Im just using that to practice with the 110octane IMI sold me. I think because 110 burns much slower, the kart actually runs cooler than it usually would ( I only saw 110degrees on temp). In all honestly, from what I know about fuel, you use different octanes, etc because of compression ratio and timing. Since the MOTOR is spec, and neither of those variable can be changed, it really shouldnt matter what kind of fuel you use. I doubt you’ll see any performance advantage at all. Just my 2 cents.
This is for Jay.
I had the same fuel as Brad’s test fuel but a different oil maxim 927.
When Brad mixed another test batch with the type of oil I was using
the matched perfectly.
It seems to me with the test gear Brad was using we would all
have to run the same fuel/oil and the same ratio.
:idn: :idn:I am sorry but I am missing something. Since the CSC rules default to SKUSA rules, what does SKUSA say about the fuel/oil?
That is what I should follow.
Help?
I think next yr. we should have a spec fuel and oil.

:idn: :idn:Thats exactly right in order to do a proper fuel tech each person would have to run the same fuel and oil. AND there would have to be a different control sample mixed to each engine manufacturers spec ratio for each motor package that was running at a given event, as it was proven over and over that the oil ratio will change the reading. Thats why deciding that there was going to be a fuel tech mid day at the last IMI CSC race made no sense to me.
