    Not very much that I have seen.

    Who peed in your wheaties this morning? If he's over 200 PSI, then some of that octane may be required. I don't need to prove it. The science is already there. Google is your friend.

    If you're that concerned about 'excess octane' of race gas, but don't have any other non-ethanol gas nearby, you can lower the effective octane level of said race gas by adding a quantity of Coleman camp fuel. The octane level of camp fuel is about 55. By doing a little math, you can easily figure out how much to add to get to a target octane level. For example:

    Adding one quart of camp fuel to a gallon of 110 race gas will give you five total quarts of approximatley 96 octane fuel. Camp fuel won't hurt anything in your saw, and contains no ethanol. Costs about $10/gallon, but you're only using a quarter of that per five quarts of total fuel...

    Tune the H side so that it burbles (four strokes) at WOT unloaded and just cleans up when under load. When you lift cutting pressure, the saw should revert to four stroking.

    I'm curious about peoples fascination with castor-based two stroke oils. They were the deal back before current generation semi-synthetic and full synthetic oils came out, but they don't perform to the same level as moderl oils. Nobody at the local pro go-kart track uses castor oils, and none of the two stroke MX guys run it either.

    If you just like the smell, get some of the scented additives that some snowmobile guys/girls run in their sleds. You can have bubblegum-scent if you want :-)

    Klotz Super Techniplate isn't "castor based" like the 2-stroke oils of old that you refer to. It's a synthetic based oil, with some castor added. I like having a bit of castor in the mix, because it still gives fantastic protection during leanout/overheat conditions. In the RC car racing world, most folks still like a smidge of castor in thier mostly-synthetic oil equipped fuels for this reason. Castor also plays well with alcohol (and ethanol is sneaking into more and more of our available pump gas every day) while many synthetics are NOT rated for alcohol. Again, it's a bit of insurance. When I'm able to run 100LL avgas I run Redline synthetic. The Kart and MX guys are NOT running pump gas with ethanol I'd wager...

    If you would read the thread you would see that I started it.

    And yes some of my saws do have over 200 PSI.

    You know if you can't read you should not comment.


    I guess it was you AND the kid who peed in my wheaties!

    Think I will just keep running my regular pump gas in my saws. They seem to get along with it pretty well and it only costs me $2.50 a gallon, plus oil. What did the race gas cost you? I have not looked in years but it used to be around $5 a gallon when regular fuel was only $1-$1.50 a gallon, now that is around my area. For the ones who are in my area, I am speaking of the Clipper Mart on Williamson Rd in Roanoke. Now that I am in Rocky Mount there is little local owned store on 220 called The One Stop Shop that sales the Cam 2 race fuel.

    I have been building race engines for 20 years, too much octane can slow down the burn rate and kill power. Now it all depends, some race gases burn quicker than others. Now for 200psi and up chainsaws, simple 100-105 octane unleaded is all thats needed, maybe not even that. I use VP SEF 94 and VP C10 unlead race fuels, runs just fine and you don't have the lead to breath. Heck the old Sunoco Ultra 94 never burned up my one saw with 205psi compression. I also run a developement engine dynamometer, so I know a little about engines and fuel. Everyone has a opinion, don't get so bent out of shape.
