I recently acquired a case of Cool Power Super T at a bargain price (maybe). A call to Morgan Fuels to find out that it is 10% Nitro, 12% Syn oil and no castor.
I dose all of my fuel with castor so bringing up the total oil is no problem.
I run Saitos and Magnum 4 strokes for the most part. Wildcat 15% with 2 oz of castor added has been my fuel of choice in the past.
My question is, should I consider upping the nitro content with some 50% nitro boat fuel? And how much castor to get this up to safe level?
I fly at sport level and have had no problems in the past with rust or scoring cylinders.
thanks in advance for your responses!l

The 10% nitro should be fine. Most likely,you'll never notice a difference even though by the time your done adding oil,you gonna have even less % nitro. You'll notice WAY more of a difference from the oil content etc. then you will the nitro content......and even then,I doubt you'll notice a difference. I'd just put some oil in it and try it. You might need a slight re-tune of the engine...but thats about it.

As a followup I found this calculator,

Actually this (and the following fuel calculator) is wrong because the proportions of the fuel part (the methanol and nitro) doesn't change when adding oil. In the OP's fuel there are 10 parts nitro and 78 parts methanol and this is what the engine runs on (and gets tuned for). No matter how much oil is added there'll still always be that same 10 parts to 78 of the actual fuel to run the engine with. To make it easier to understand, if you use a fuel with only methanol and oil then the engine runs only on the methanol (100% of it). Add some oil and the engine still only runs on the methanol even though you'll have had to open the needle slightly to account for the extra oil but the fuel side of it is still just 100% methanol.

Getting back into rc flying after some family medical issues. So, got this case of fuel and I have been dosing it with 5 1/2 oz of castor per gallon and it seems to work ok. Question I am posing is, would the blend work better with a little less castor and maybe some Klotz KL 200 oil? I have a quart of 50% nitro boat fuel to add if needed. I am flying mainly 4 strokes but recently added a OS 160fx for a Chipmunk to my engine collection. I would like to end up with something comparable to 'Wildcat 10% premium'. thanks in advance to any and all responses.
