Way too many variables to answer this question. Year make, engine size, hitch type, tire size and rating, transmission type, number of marbles between your ears. Here's a rule of thumb. If it will roll down the highway at 55 mph and your not floored, your probably OK. If you can climb the hills without a mile of traffic behind you, your probably OK. If you never bury the temp gauge, your probably OK. But remember, you can't tow something bigger than the truck.
16 gallons
3500LBS for V6, 3000LBS for 4-cyl
I have read in several places that the towing capacity for 4 cyl. Highlanders is 3000 lbs. For the 6 cyl. ones, it is 3500 lbs.
It holds 5 quarts
I do some towing and long trips. I check my tires and get about 70,000 out of them.
for years, Firestone has changed the oil on my 2001 4 runner. They always filled it with 5.2 qts and now they are filling it with 5.5 qts. What is the capacity of a 2001 Toyota 4 runner limited with 2wd?
When doing a drain and fill on a Toyota 4 Runner, it takes about 4.5 quarts to refill. It is important to use the correct type of transmission oil.
It really depends on how much your objects weigh and how big your trailer is.
Towing a 1994 4-runner is possible, but it would take a heavy duty truck, most likely. A 4-runner weighs about 2 tons, so it needs something with good tow capacity to tow it.
Towing capacity of the 4 cylinder is 1,500 pounds.
5.5 Quarts with oil/filter change.
4 cylinder engine: 3,000 lbs - - - 6 cylinder engine: 3,500 lbs.
