Default oils

hi all.
i have been testing oils and oil percentages in my fuel.
i use jp's and run 16% nitro.
the questions are.
1- what oils cool.. the castor or the synthetic?..i use both in my blend..
2- using more synthetic as to castor gives me more acceleration..why is this?
3- when using 8% oil as to 10% oil, the motor revs harder but hotter.
4- i added 1 x .1 head shim (now using 2) and the motor cooled down by 20 deg.. why is this?
5 - i want the best run time, the best performance and most importantly.. i want my motors to last..
i do realise that i might be pushing sh#t up hill. i see the top runners always replacing rods after the quilifys.. i cannot afford to do this, but i still want to keep up with them...
any suggestions would be greatley appretiated.
mike

I think you've got # 5 figured out. Those guys that change rods before the main are probably running less oil and leaner settings to qualify and know they used up the rod bushings doing it. In order to stay with them you may have to do the same. It's hard to stay that compeditive on a budget.

The following information was sourced by Don Nix, past owner of Powermaster fuels. I'm just paraphrasing it a cuz its a long article to answer your questions.

1. if you are looking at temperature number only, castor oil will tolerate a higher temperature of than synthetic. there are characteristics involved that gives synthetic other advantages that castor does not have.

2. i honestly dont know the answer to this as there is a huge variety of synthetic oils available.

3. if you are using less oil percentage, that means the other content of the fuel must be increased by ratio. the engine will rev faster/harder but it also may not be as well protected.

4. i'm not very familiar with internal engine tuning, sorry.

5. basically the best compromise is used by current fuel manufacturers, which is a castor synthetic blend since it gives the best of both worlds.
