Toyota just specified new oils.

If 5W-20 oil "cannot maintain lubrication effectiveness in engines with older designs", then why does the owner's manual for my 2003 Ford Ranger specify 5W-20 for the 3.0 liter Vulcan V6 that's in the truck when that engine has been around for at least 20 years? I'd say that's definitely an older design.
Since this is a Toyota service bulletin I think it's safe to assume they are only talking about Toyota engines.
And it doesn't say "5w20 cannot maintain lubrication effectiveness." It says that ALL the oils listed can't maintain lubrication effectiveness in older engines, which as I've pointed out is pure nonsense because Toyota has specified 5w30 in their engines for years.
The link that 'i' gave is to a car forum, and my impression is that everything between the asterisks is Toyota's--everything after the asterisks is the poster's comments.
Nevermind
I've seen one line online about Toyota TSB EG018-06 that looks similar to this, but you have to be a paying subscriber to get the PDF document.

Huh!? I couldn't make heads or tails of that document. I'm happy with my 5W30 anyway. If I was to try a 20 weight I'd go for 5W20 in a synthetic variation. I've already tried a 0W30, and for them to say it can't maintain lubricatrion is preposturous. The Amsoil S2K is thicker than Mobil 1 5W30. It matters not.

What's not to understand? What Toyota wrote there is basically the same what VW/Audi wrote back in '99 when they started using low viscosity oils in many (most) of ther new engines. They also noted exceptions -- and given the number of equipment (WIV) and engine options, there were plenty exceptions.
Of course, VW/Audi were morons in the first place for (prematurely?) beginning to use low viscosity oils, and by now they have stopped using those altogether in their latest engine designs.
I have a copy of the following:
Technical Service Builletin March 29, 2006
Engine: EG018-06
Title: Ilsac GF-4 Engine Oil Recommendation
Models: All '06 - '07 Toyota & Scion
TSB UPDATE NOTICE:
The information contain in this TSB supercedes TSB No. EG001-06. TSB No EG001-06 is now obsolete and should be discarded.
Introduction:
Toyota Motor Corporation manufacturing plants have begun using ILSAC GF-4 engine oil. This engine oil is recommended due to its superiority in terms of fuel economy and engine protection and due to its benefits for both the customer and the environment. ILSAC GF-4 can be used in all Toyota and Scion engines.
Note:
- The recommended viscosity grade for this oil differs according to vehicle model. Use the recommended grade specified on the oil filler cap or in the Repair Manual or Owner's Manual for each vehicle.
- For Prius vehicles, refer to TSB No. EG050-04 "Engine Oil Specifications."
Applicable Vehicles:
2006-2007 model year Toyota and Scion vehicles.
Warranty Information: Not Applicable to Warranty
Recommended Engine Oils:
ILSAC GF-4 SAE 5W-20:
This oil has been set as the Toyota genuine engine oil, starting in February 2006 for the US. This oil is superior in terms of fuel economy, engine protection, and cold starting performance.
ILSAC GF-4 SAE 0W-20:
This oil has even better fuel efficiency and cold starting performance than 5W-20. Initial application for 0W-20 is in the 2006 model year 2AZ-FE engine and will be used in new engines to be developed.
Engines That Can Use 5W-20 and 0W-20:
Engines using ILSAC GF-4 SAE 5W-20: AZ series, GR series, JZ series, MZ series, NZ series, RZ series, UZ series, VZ series, 1ZZ-FE, 2TR-FE.
Engines using ILSAC GF-4 0W-20 (beginning with 2006 model year): 2AZ-FE Camry, 2AZ-FE Solara, 2AZ-FE highlander, 2AZ-FE RAV4 (ACA#3).
NOTE: 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.

Oh, and Scion comes through too!
So from this posting 'our' 1ZZ-FE is able to use 5W-20?
Yes, the original post had some typos...
Great work Javacontour.
I see the GR series is listed as factory filled with 5w20. I wonder if that's what's in my new 1GR-FE Tacoma? I will have to converse with my dealer about this TSB and get their take on it.

IF it's a 2006-2007 Yes.
If it's a 2005 or before NO.
They did change in the 2006 model year to hold more oil.
Who knows what else?
Take care, bill
I wonder if and when this new info will filter down to GM and their 1zzfe Vibes?quote:

Great post - thanks man!

Soon to be runnin' 5w20 in the tC!

Glad Toyota is validating the choice I made a year ago. Lemme buy a round of 5W-20 for all the new yota owners!
I need to make a trip to my local dealer about oil choice. I would think that the 05 Corolla's can use 5W20. If I can, and get slightly better fuel economy out of my car, I want too. Although I still have enough Redline 5W30 to last until the end of summer.
Well, I have to wonder what changed in my 2006 tC from the 2005 tC?
