I know someone will ask why I said not to use Canola oil. There's a LONG explanation, but here's a quote from a website that sums it up pretty well.

Rapeseed oil is the source behind mustard gas, and on its own, it causes emphysema, respiratory distress, anemia, constipation, irritability, and blindness. But through the beauty of genetic modification, we now sell it as edible oil.
The claim is that canola is safe to use because through modification it is no longer rapeseed but “canola.” Except… canola is just genetically modified rapeseed. It has been marketed as wonder oil that is low in saturated fats with a beneficial omega-3 fatty acid profile. It is recognized by the American Dietetic Association and the American Heart Association based on the belief that the absence of saturated fats alone makes it healthy.
It is now believed that rapeseed has a cumulative effect, taking almost 10 years before symptoms begin to manifest. One possible effect of long-term use is the destruction of the protective coating surrounding nerves called the myelin sheath. This is like having raw, open wires in the body. Some symptoms include:
tremors and shaking
uncoordination when walking or writing
slurred speech
deterioration of memory and thinking processes
fuzzy or low audio levels
difficulty urinating/incontinence
breathing problems/short of breath
nervous breakdown
numbness and tingling in extremities
heart problems/arrhythmia
From a nutritional perspective, canola oil has been found to deplete Vitamin E. It has a tendency to inhibit proper metabolism of foods and normal enzyme function. It also depresses the immune system.
