New info on Amsoil's EaO09 & EaO10 Oil Filters - Toyota Yaris Forums

Lazerdot · 08-09-2009, 06:31 PM

Yarstar,

The EaO9 filter used on the 1.5 liter engine should be changed at OEM intervals. The EAO filter still provides superior filtration and better flow, but because of the higher then usual contaminates found in Toyota engines, Amsoil has been proactive to prevent any issues. Keep in mind that most other filters out there get changed at OEM recommendation as well and may not provide the same filtration. My Understanding is that your oil is still usable if you are using AMSOIL for an extended drain interval, just change the filter and top off the oil. Always change the filter when you change the oil regardless your oil/filter brand.
The fuel dilution mentioned is a new issue. The TSB I have indicates high levels of silicates produced by the engine being the issue.
I can get you the TSB on the Toyota/EAO filter if you'd like. Send a message to Greg@TruLube.com.
