Thanks for that correction, SilkySmooth. I didn't read the TSB. It's been referenced on here several times as OK'ing 5W-20, and I repeated what I'd read.

The TSB SPECIFICALLY LISTS engines that CAN use 5W-20 as genuine Toyota oil moved in this direction. The NZ series is listed. It dosn't say you have to use it.
Mine purrs on 5W-20-no noise issues at all-not that sound has much to do with it. R2 |

Well, when Toyota gets serious enough to move the 5w30 off of the oil cap & manual and replace it with the words 5w20 I'll get serious about the TSB. And if oil doesn't qualify as a sound issue with a motor I don't know what does.

Well they haven't taken the GF-3 off the cap either-and GF-3 has been obsolete for many years
My point about the sound is that thicker oils tend to dampen noise better than lighter oils but it is not necessarily an indicator of increased wear. Oils of the same viscosity can also exhibit differences in sound dampening depending on how they are formulated. At any rate I think the intention of the TSB is quite clear and the NZ series is plainly listed in the 5W-20 column. Warranty wise GF-4 in either 5W-20 or 5W-30 would be fine. I'll try to get Toyota's official take on this next week to clear up the confusion. R2 |

Well, I know you're certainly not the first member here that went back to 5w30 after trying 5w20, stating that more noise was noticed with a 5w20 fill.

I'll be changing the oil in 2 weeks and I'll let you know if there is any audible difference. I am guessing that there will be zero.

I'll just go by what you and other members say. Some notice a difference, some say no change. I myself don't know about the NZ because I've always stuck with the 5w30 so far.

if i can find it cheap i'll get with the 20, otherwise i'll get 30.
i had no idea that this would spark a huge debate. i was just wondering about the 0w. i notice it pours like water and is very thin, but then again it's supposed to be. it has anti-bubbling agents and wear protectors in it just like the 30, it has the winter additives just like the 30, but it's just a little thinner at temp. my main thing was the 0w. so my question has been answered and i appreciate the comments |

so were you considering 0w-30 or 5w-20 or 0w-20?

I just picked up some of the 0w-30 and will keep an eye on the mileage to see if it improves.

So I called Toyota customer service today and got the mantra about "use what it says on the oil cap"-and got the same from the dealer. Both seemed unaware of the TSB and neither seemed to know why a 2009 MY vehicle would still be specing ILSAC GF-3 and API SL via oil cap. (Neither even appeared to know what to heck I was talking about for that matter).
That TSB is one confusion causing document judging by the similar discussions I've seen elsewhere on the net. I guess the only for sure is to use the 5W-30 at this point. R2 |

As for oil specifications, there have been a few exceptions in recent years, but the normal presumption has been that successive specifications cover earlier ones, so "GF-3 or better" is how I'd read that. My oil caps don't mention anything except 5W-30.

Yep I agree Yaris-I just don't get the bugle blowing about GF-4 in the TSB then leaving GF-3 on the cap 2 model years afterward.

Jeepers - the TSB says AT THE TOP IN RED OUTLINED BOX NOTICE: ' use the grade that is on your fill cap and in your manual' how more CLEAR do you want? So you just put in a lower grade that can DAMAGE you engine? Even the owners manual recommend THICKER oil for high speed highway and other severe operating conditions to properly lubricate the engine. Going DOWN a grade puts you into - spin a bearing, collapse a skirt territiory. The Title of the TSB is not "substituting 5w-20 for Toyota Engines" its, "ILSAC GF4 Engine Oil Recomendation" - but like we have a choice to buy GF3. Terrible, confusing TSB, toyota better get their act together!
