I posted about this in another thread but I will post again here. I have the XRS (03) which takes 4.8 qts w/ filter to full mark.
On a similiar note. I also have an 04 Tacoma with the 2.4L engine. The book says drain and fill with filter is 5.8 qts. The actual fill to full on the stick is 4.8 w/ filter. I asked Toyota and they told me to go off the dipstick essentially. I will edit with the e-mailed response. I was told by the dealer that they only put 4.5 qts in those engines. I was also told that they used to put like 7 qts in the Tundra's until they realized that that was too much oil so they replaced the stick and now only require 6 qts (approx).

Thank you for contacting Toyota Motor Sales, U.S.A., Inc.
We appreciate the opportunity to address your concerns.
The information in your owners manual regarding the oil capacity of your 2004 Tacoma is correct. Please be advised, however, that the proper oil change procedure (especially in regards to gradually refilling the oil, and checking with the dipstick) must be used to ensure that the engine is not overfilled with oil.

I own a 2004 Tacoma Ext cab 2.4L. The owners manual states that the engine oil capacity of this engine is 5.8 US qts w/ filter. This appears to be a misprint as the full mark on the dipstick is achieved at 4.75 qts. I changed my oil once and used this number. If I hadn't have checked it within a few miles, who knows what could have happened. I have seen this 5.8 figure in several publications and feel that it is misleading and could lead to engine issues that Toyota wouldn't cover due to excessive oil in the engine. I have spoken with my local service writer and was told that their techs put no more than 4.5 qts in the engine. If you are aware of the problem, what are you doing to correct it? If you aren't aware, I would hope that you could notify those owners and hopefully save them a hassle down the road. Thank you for continuing to build quality vehicles.
