Drops vary in size. The usual slow drip I see would be about .05-0.10 ml (cc) in size or 5 to 10% of the size mentioned in the article (I used to work in a chemical lab). I call 6 drops a minute a fast drip. However, his oil loss calculations are correct. 6 drops/minute X 24 hrs x 60 min/hr X 0.1 ml/drop = 864 ml, or about 0.9 liter or about a quart (1 qt = 946 cc). So that is a respectable leak. If it indeed was a full ml per drop, that would be 8.64 liters, or a flood. Multiply 0.9 by the cost of the oil, and you have a decent estimate of the $$ you are losing. Pretty fair-sized leak. Don't know how he came up with 6 drops per minute, though.

Hi Jayman,

Well, I'll take the whole thing with that proverbial grain of salt. That's a pretty big drop they are using in the calculation! One cc in volume is equal to a little more than a cube that is 3/8" on a side. That's not my idea of a drop.

Oil leaks of all kinds should be repaired but I think that analysis overstates the cost associated with them; at least those that individual tractor owners are typically involved with.

You made an excellent point about the size of the drop- must be an awful high viscosity to amount to one cc per drop. Also note that their oil price is about $12 per gallon- and what did that drip cost- about $1000 bucks per year? Always nice to deal in big round numbers, even if they are not justified.
