Thank you for contacting Scion.

We appreciate the opportunity to address your inquiry.

No, 5w30 is the recommended oil weight for your 2006 Scion xB as specified in your owners manual. Use of any other weight can void your warranty.

Please feel free to contact us should you have any further questions or comments. We would be happy to assist you. You may contact us directly at 1-866-70-SCION or by email at Contact Us.

Thank you for your interest in Scion.

I'll bet this guy has never seen the TSB on the oil switch. You'd be better off calling the Service Manager at you local dealer but still need to make sure he is aware of the TSB. Most over the phone Customer Service people are basically telemarketers.

Ok, so I emailed Scion just to see what they'd say. Here it is...

Thank you for contacting Scion.

We do apologize the information you seek is not more readily available for you. The engine oil 5W-20 is the ideal engine oil you would want to use for your 2006 xB, reasons being are for its low-viscosity which make it ideal for the reasons you listed. At this time, we are unaware of any negatives for using this oil and the TSB #EG018-06 was issued to specify to use this engine oil if your engine fell under the engines listed.

Please feel free to contact us should you have any further questions or comments. We would be happy to assist you. You may contact us directly at 1-866-70-SCION or by email at Contact Us.

Thank you for your interest in Scion.

My questions are about the recommended oil for use in my 2006 Scion xB. I know there is a TSB (EG018-06) from March 29, 2006 which changes the recommended oil in the owner's manual (5w-30) to a lighter weight (5w-20). Is 5w-20 safe to use year round? Are there any negatives to using 5w-20? Is 5w-20 what came in my Scion from the factory?

ILSAC GF–4 SAE 5W–20
This oil has been set as the Toyota genuine engine oil, starting in February 2006 for the U.S. This oil is superior in terms of fuel economy, engine protection, and cold starting performance.

Engines That Can Use 5W–20 and 0W–20:
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

Clearly they have no standard response- just seem to repeat what you want to hear. Like you said, there's minimal difference between 5w-20 and 5w-30 so it doesn't really matter. But if 5w-20 wasn't the correct specification, I hope they would've said so!

Can you let me know how that UOA turns out?
Im curious as to PP's numbers as I made the switch to PP from M1.

Absolutely.

I have oil analysis performed on my xB when I have 20,000 miles on the oil. I change my oil and filters every 25,000 miles. I am using AMSOIL TSO 0W-30. Made the change at 5,000 miles (first oil change). Then changed at 25K and 50K. Now have 62K on car with three great oil analysis reports. I will be glad to share, also.

First oil change at 5K: AMSOIL HDD 5W-30
Installed AMSOIL Dual Remote By-Pass Filter system at 7,400 miles
First analysis w/10K on OIL (14.6K on odometer)
Second analysis w/20K on OIL (24.7K on odometer)
Second oil change at 25K: AMSOIL TSO 0W-30
Third analysis w/20K on oil (45K on odometer) look at those LOW ppm!!!

Car now has 63K on odometer and will perform next analysis and oil change at 75,000 miles....that's right....my FOURTH oil change!!!

And yes, I have the AMSOIL synthetic gear lube in my trans w/NO PROBS!!

change your mind...not your oil

And for the record, W doesn't stand for weight. It stands for winter.

Ur absoluetly right. The 30 is the weight of the oil in 5W30. When starting from a cold start ur oil will be at a viscosity weight of 5 and as it warms up to operating temperature the oil thickens to the 30 weight. This is done for winter months because if u were to run straight 30 the oil will be so thick that u probably won't be able to start ur enigne and even if u can the pistons will not get sufficient lubrication, heat up and seize. If u live in a warmer climate like florida a 10W30 is good because u'll never see northern temperatures during the winter months. For racing applications u can run straight 30 40 or even 50 weight since all u'll be doing is racing the car, and straight oil weight is usually designed for racing. If u go to ur parts store u can buy straight racing oil.

I was doing a web search for the oil type to use in my 2006 xB and came across this thread. Another thread on another forum turned up the TSB here and here.

It looks to me like the 2006 xBs can use ILSAC GF-4 SAE 5W-20W oil, and any Toyota can use ILSAC GF-4 oil.
