When the Runnertime distributer in Australia stoped brigning it in there was a massive gap in the Australian market and there was no good quality high end product available. Some Aussies might disagree with this, but quite frankly not much lives up to the runnertime mark.

I brought in a batch of Tornado after runnertime ceased being imported into Aus. It was a good fuel with great run time and it seemed quite consistent. The problem with Tornado was it didn't have the castor oil content of runnertime, so on high speed tracks with large straights it didn't provide sufficient long term protection to engines. People quickly began adding castor oil and it seemed to improve the strength of the protection during WOT.

A friend who races more often than me now places an extra 1% pure castor oil into the Tornado fuel for that extra level of protection. I believe the engines need it, and a large group of racers in Australia do the same i believe with a variety of brands of fuel. Ultimately the extra 1% castor improves idle during long races, and makes the tune more consistent, less flame outs and just a better overall performance of the engine.

I have purchased some RB fuel but i haven't used it enough to know if it is as good as Tornado or Runnertime. The one thing i noticed with RB fuel is there is significantly less smoke at the exit of a corner...but again i haven't used it enough to know for certain as i switched back to using runnertime at the last race i entered.

i will most probably add an extra 1% of castor to my RB fuel. it doesn't detrimentally affect performance and it improves high speed protection.

But yes, I know even top sponsered drivers who do add a small amount of castor oil to their fuel to save the engines. It is sad that it is needed but it is also one of those "secrets" most people do not tell.

I have 4 engines broken in a week, all of them die coz of detonation in high rpm. Tornado gives me confidence and get rid of engine damage.

RAPICON only using synthetic oil.

low grade methanol will cause corrosion.

low grade castor will most likely just gum up the motor not corrode

i have been mixing my own fuel for ten years using vp rc3 castor oil and never had a problem with castor oil or runner time fuel for when the worlds where here.....

i had one bad batch of methanol that caused excess wear on the motor... i know that it was the methanol due to i always get it from the same place . just the one time i got it else where and had the problem.

you can tell its the methanol by looking in the motor, if there is a yellowish colour on the internals of the motor..

i see it all the time people buying the wrong fuels and blowning engines...

there is 3 grades of methanol you can get "in australia" they are approx 80% , 90% and the 99.99% this is the one you want to use..
