Question: How much oil and what type of oil should  I use in my VMAX 46PRO or 52PRO?

Answer: The 46PRO and 52PRO should use fuel having no less than 18% total oil and the oil should be blend of synthetic and castor oil.

Better Answer: Using less than 18% oil in fuel supplied to a VMAX 46PRO or 52PRO will result in overheating, premature wear and engine failure. Using pure castor oil is OK. Using pure synthetic oil is NOT OK. The best oil mix is 19-20% total oil and the oil should be a blend of synthetic and castor oil.

Use commercial brand name fuel. Stay AWAY from home brew, old or brands of fuel that are not common in the marketplace. If facing a choice between a fuel that has a bit more oil and costs a bit more... go with the richer oil package for a buck or two more. A gallon of fuel lasts a long time and it is simply not worth risking what you are putting in the air to save a few bucks. Skip one burger a month and use the extra cash for good fuel!
