Moved to 5w20 based on TSB: EG018-06, which allows for 5w20 with GR series engines, which the 2007 4.0L V6 is.....
It's doubtful your choice of oil or weight has anything to do with the problem, however last year I sent an email to Toyota because I noticed AAP's computer also shows it being back spec'd to 5W20 the following was there response:
Thank you for contacting Toyota Motor Sales, U.S.A., Inc.
We appreciate the opportunity to address your inquiry.
SAE 5W-30 is the recommended oil viscosity for the 2006/2007 Toyota 4Runner V6 and the Toyota Tacoma V6. In terms of maintaining the integrity of your warranty, our recommendation is adherence to the Scheduled Maintenance Guide. The engine oil and filter should be replaced every 5,000 miles or 6 months, whichever comes first.
The recommended oil capacity is 5.5 quarts with a filter and 5.2 quarts without the filter change for both the 2006/2007 4Runner and Tacoma.
We recommend you follow all of the specification in the Owners Manual. Please refer to the section titled “Specifications” in your owner’s manual for more information. The manual is available online at
www.toyotaownersonline.com.
