FYI – for more information, I started with the Scion xB owner’s manual. The engine is: 2.4L 4 cylinder (2AZ-FE, no turbo charger, wife’s car) page 260 and engine lubrication 4.5 qt with filter change (page 261). Page 238 shows a diagram for checking the oil level dipstick. Clearly marked above the “top” dipstick mark is a label stating “too full.” 4.5 qts places the oil level above the top mark by 1/2 qt. I have researched this issue with no solid answer but it appears to be prevalent.
The engine referenced regarding the Camry is from 2009 with similar experience and same engine model yields similar response not only on his personal car but on his many client’s Camry automobile as well.
I have a 2000 Toyota Avalon, 1995 Camry, 1972 FJ40, 1975 FJ55, and 1993 FJ80 Toyota Landcruisers. In ALL cases, the capacity measured on the dipstick has been exactly what the manufacturer spec calls for with the total volume of oil placed into the vehicle at the appropriate mark on the dipstick. This is the first “Toyota” product (Scion is a Toyota Product but built in Japan versus in the US) that I have owned that has created a concern regarding the oil change. I have done many and continue to teach my 4 children how to check the oil level and change their oil in their automobiles.
So, If you were not aware that the Toyota and Scion vehicles were the “same” engine and that this is a perplexing issue that continues to not be addressed, please enjoy hopefully additional responses to this post that are enlightening.
For example, the water pump failure on this engine occurs in both the Camry and Scion since it is the same engine.
Reason for concern is that the Previous Owner, had the dealership change the oil at 5000 miles per specs. However, what I have learned is the oil level stays rock solid up to 3000 miles and when it starts to get more miles on the oil, it tends to lose a little oil; probably by minor burning (speculation). However, there is a Toyota technical bulletin on oil burning for this model engine. Therefore, I change the oil every 3000 miles for all my automobiles; including the Scion. My wife drives this vehicle. She does not check her oil level as often as I would like her to. Being short 1/2 qt after a change to ensure that one does not exceed the “too full” dipstick level mark is significant in a vehicle that is known to lose oil - in my case after the initial 3000 miles of wear on the oil. I use Mobile 5000 5W20 per spec.
So, hopefully, now that I have explained my concern more fully, you can understand why I am looking to the Camry issues that are applicable to my situation.
Thanks again, posts welcome.
