No worries, a few dollars from the wallet, perhaps, but not the thousands a new engine could cost. Do not drive the vehicle with that much antifreeze in the oil. Drain the oil, replace the oil and filter. Now drive around for a while (a day or two normal driving, assuming it's enough to get the engine up to normal operating temperatures). Replace the oil and filter again. This should be sufficient to cleanse the antifreeze from the system, but watch for white or antifreeze colored foam on the oil dipstick indicating the continued presence of water or antifreeze in the oil, in which case, replace the oil and filter again.
1 gallon
1 gallon in a standard antifreeze jug.
Top to bottom vegetable oil, kerosene, antifreeze, water.
One gallon of antifreeze mixed with half water
1 gallon of antifreeze mixed 50/50 with 1 gallon of distilled water will be enough to fill the system.
Full strength antifreeze (coolant) is about $9-$12 per gallon. The premix (50/50)coolant is a few dollars cheaper.
one gallon is equal to 4qt and a 1qt equal to 32oz
You want to use a 50/50 mixture of water and antifreeze, but use the manufacture recommended antifreeze, it comes straight anti freeze in which case you would mix a gallon of antifreeze to a gallon of water or you can buy a pre mixed container of antifreeze if your just trying to top off
It depends on how dilute the antifreeze is, for cars, antifreeze is usually a mixture of antifreeze and water. However, ethylene glycol is the main component of antifreeze with a density of 1.09 grams per centimeters cubed. Or 1.09 grams per mililiter which is 1090 grams per liter. One gallon is 4 quarts or 3.7854 liters. So, 1090 grams per liter, times 3.7854 liters equals 4125.65 grams. Times this by the conversion factor of 1 pound equal to 453.59 grams. Then, a gallon of ethylene glycol weighs about 9 pounds. An undiluted gallon of antifreeze weighs 9.33 pounds per gallon.
2 gallons.
With any luck the engine shut itself down before serious damage occurred. Definitely change the oil and filter, it certainly can't hurt, try to start it (something may need to be reset, consult the dealer if necessary) and if it does, drive it a bit if it seems to be running ok, but shut it down at the first sign of trouble. If it seems that it will run ok, then drive it for a day or two, then replace oil and filter again. Drive around some more. This should be enough to cleanse the antifreeze from the system, but check the oil dipstick for white or antifreeze colored foam which will indicate the continued presence of water or antifreeze. Change the oil and filter again if necessary. Consult the dealer about which, if any, seals or sensors would be damaged by this experience and replace them as required. Keep watch on the engine's operation and make repairs as necessary. You should probably also have an engine check-up performed by a tech/mechanic you trust.
The typical mix is 50% water, 50% antifreeze. This mixture will protect the coolant to aprox 34 degrees F below zero. Purchase one gallon of antifreeze and pour half of it into a clean gallon container. Fill the containers with clean water and now you have two gallons of premixed engine coolant to keep on hand. Add the premix to the full line on the coolant reservoir when the engine is cool.
