question about 1st gen tacoma

is it ok to fill my 3.4 v6 with only 5 quarts instead of 5.5 as im worried about over filling it because they dont sell half quart bottles

 

Welcome to the forum

It is always best to have the oil topped up to the full mark on the dipstick.

If you look at the side of any quart oil bottle you will see a scale showing the liquid level.

Just add a bit and check the bottle, save the remaining 1/2 quart for top up or the next oil change, the oil will be fine with the cap on tight.

 

What he said ^^^^

 

I've always filled mine with 6 quarts. It hurts nothing.

My last 3.4 went 300k miles before I sold it. My present 3.4 is at 120k miles.

 

Should probably be explicit given the nature of the original question…

Slightly overfilling will be fine, severely overfilling will cause problems
