I would like to change the engine oil of my 12R 4-cylinder toyota,how much in liter oil capacity needed?

Should be 4.2 litres with filter.

Engine lubricant oil capacity: 4 liter / 4.2 U.S. qt / 3.5 imp. qt with filter change Engine coolant capacity: 6.5 liter / 6.9 U.S. qt / 5.7 imp. qt Fuel tank capacity: 65 liter / 17.2 U.S. gal / 14.3 imp. gal Transmission oil capacity: 1 liter / 1.1 U.S. qt / .9 imp. qt Final drive oil capacity: 1.1 liter / 1.2 U.S. qt / 1 imp. qt Battery capacity (Ah): 50 Spark plugs: Bosch F7LDCR, NGK BKR6EK

I have toyota emina,diesel engine, i change oil every reaching 5000 kilomters on guage, with 6 liters diesel engine oil.

If it's a 4 cylinder it's a 2.4 liter. If it's a 6 cylinder it's a 3.0 liter. The 2.4 liter engine comes with a carb, Fuel injection or even a turbo. Either way the 2.4 and the 3.0 take the same oil filter. The bosch is # 3330. I hope this helped and good luck.

Most 4 cylinder engines have a capacity of between 4 and 5 liters.
I would put 4 liters in , run the engine for a minute or two , wait a couple more minutes for the oil to drain back down into the oil pan , and then check the dipstick. Vehicle should be on reasonably level ground to get and accurate dipstick reading.

this toyota 4 runner takes 5.2 liters of oil and the correct oil is 5W 30 motor oil. hope this helps.

if you have a 1ZZ engine

4.2 quarts, 4.4 quarts with oil filter change

if you have the 2ZZ engine (XRS model) it is

4.4 quarts, 4.6 quarts with oil filter change

NOTE these are updated capacities that reflect changes identified in TSB: TSB-0134-08 issued July 15, 2008.
Your owners manual will reflect a lesser quantity that Toyota has since revised.

it's a 4 liter oil
