    I need to go pick up a couple cases of oil and got to thinking...On the 05 to present V6 motors it seems Toyota has changed the recommended oil viscosity once or twice. Has anyone with the older models that use 5W-30 been advised by Toyota to switch to something different? Correct me if I'm wrong but I believe Toyota is now calling out for 5-20 to be used in the newer Tacoma's with the V6.

    Look in your owners manual. I'm pretty sure its 5w-30 for most areas with what could be considered 'normal' temperate zones. It's when you get into the colder climates that require something different (it's in the manual).

    I am new to this forum but i have been working on and for Toyota since the early 80's. The post that sad look in your owners manual is right.The newer motors are running much tighter oil clearances that require lighter oil's. :)

    Toyota provided guidance in a TSB for use of ILSAC GF-4 or 5 fuel economizing oil in the V6 engine (GR1). The weight they allowed is the 5w20. Using it does not impact warranty just be sure to look for a fuel economizing star burst on the bottle so you know it's rated GF-4 or 5.

    I don't have the TSB number but I'm sure you could search and find it.

    I would say you would be safe with either 5w20 or 30. I run 5w30 and have yet to have any issues. Most of the manufacturers are telling evryone to run the 5w20 for fuel conservation, thats the reason Jeep went to it in the new Wranglers they have a hard time getting good gas ratings on those things so they take every little bit they can to get more MPG's.
