[ECrepeau]

Per the TSB that has the change for the V6 from 5w-30 to 5w-20 has anyone strated doing this is is most everyone still running 5w-30?

I've a 2007 V6 and switched over to Pennzoil Platinum 5W-20 at 1000 miles. Running great; haven't noticed an improvement in fuel economy yet.

Taken directly from the TSB...

"DO NOT use these oils in engines other than those listed above. These low-viscosity oils cannot maintain lubrication effectiveness in engines with older designs and could result in smoke emissions from the tailpipe and/or unusual engine noise."

I realize that our engines are listed -- however, as the only benefit is a slight mpg increase, I'll stick with 5W-30, thank you.

Also, I have about six cases of 5W-30....

i use a castrol 5w-30 synthetic blend.

I use Valvoline Syn Power 5W-30 in both my rigs and I have had no problems. Stick with the 5W-30. Just my .02

I service cars & trucks all day long and i tell ya what, that 5w20 is like water. Synthetic 5w20 is even worse!!! I'll keep some viscostiy in my motor...lol

mobil 1 5w-30

never thought about switching.

Does an '07 V-6 have an engine listed on here? I'm dumb and don't know my engine's model number. I assume the 0w20 doesn't apply to us.

[ECrepeau]

Yes, this TSB is for the '07 V6. I have the same engine but based on the comments above I think I am going to stick with 5w-30. Here is a link to the engine. we have the 1GR-FE

Rone,

It's the 1GR-FE, so it's on there.

I switched to 5-20. Castrol GTX. More flow through the filter, and thicker oil doesn't necessarily lubricate better.

I might try it next oil change.

dino 5w20 and syn 5w20 are different viscosity? they're not both 5w20?

how come dudes here disagree with Toyota's recommendation to use 5w20? i know about "they only tell you to do that to achieve better fuel efficiency ratings". but, didn't they build the truck and know what is best for it more than we do in web world?

the advice you get onthis forum is sometimes worth what u are paying for it... ;]
