Hey here is a plain and simple way to get the amount of oil that your truck takes right....k ready here it goes....remove the D3 oil filter but do not install the new one yet!...lift up the truck by whatever means necesary or crawl under it and drain the oil...let the oil drain untill it drips or stops dripping whatever our preference is...then reinstall the drainplug with a new gasket and tighten it up...then get out from under the truck and grab the new oil filter either a D3 or a G1 (the G1 is what they use on the 3.4 and some other motors and is also smaller height wise than the D3 filter and glossy so it will add a lil bit of gloss to your engine bay :top
and screw it on hand tight...remove the oil cap and pour in 4.5 quarts of your favorite oil, then start the engine and let it run for 30 to 45 seconds to circulate the oil and fill the oil filter...shut the truck off and let it sit for a few seconds then check the dipstick...if it is low than add another .5 quart of your favorite oil and recheck the dipstick still low? Add another .5 quart of your favorite oil and recheck the dipstick...still low???!?! Proceed by adding another .5 quart of your favorite oil and rechecking the dipstick...between the 4.5 quarts of oil and 6 quarts of oil you should have reached the middle of the dipstick or the uppermost dot. Enjoy!!!:rockon: I work at Street Toyota in Amarillo, TX and in all the 4.0L 05-09 Tacomas, including my X, our digital readout oil despencing guns all read 6 quarts by the time im done changing the oil using the D3 oil filter and that fills them to the top dot on the dipstick...we have never had any issues reguarding damage done to the engines when using this amount and imo i was taught that the bottom dot ment "low" inbetween the dots ment "ok" and the top dot ment "full"...YES the book is wrong! But common sence by checking the dipstick cant be wrong can it? Im neither taking a side in this post nor bashing one. Everybody has their own way of doing things, thats what makes us unique.
