5W-30 VS 0W-30 (3RZ)

Ok so I have a 2001 Tacoma 2.7L (3RZ) and was told that I should run 0W-30 to get better gas mileage out of it as I was complaining to a friend about how I only get about 300mi out of a full tank. Is there any truth to this? I would love better gas mileage but i always chalked it up to the bigger tires I have on it (285/75/16) I love my truck and it’s my daily driver until it get my 2018 civic fix as I was in a wreck and have some harness issues. What are you all thoughts and opinions on this ? I have used Lucas Oil 5W-30 synthetic most of its life along with a few qts of there heavy duty oil stabilizer added to the oil since I have close to 200k on the clock.

 

I'd keep using 5w-30. I doubt the fuel mileage gain from switching would even be noticeable.

If it aint broke dont fix it.

 

Come back and ask this question on Friday.

 

and I’ll suggest 20w50 on Friday

 

Shell RotellaT1 straight 30W when it's hot out and stuff. I don't trust
those "W" numbers: Nobody knows what they mean.

Is it Friday yet?? Close enough.

 

Close enough to being Friday….

 

I use Rotella 5w-40 with my 3rz

gas mileage is still plenty good…
