vehicle-----------------04 Toyota Echo, 1NZ-FE, 1.5L, 4 cyl
OIL---------------------Amsoil SSO 0w-30
oil additive------------none
Make up oil-----------none
Engine oil capacity---4 quarts
oil filter----------------Amsoil EAO09 or EAO10
air filter----------------Wix
miles on oil/filter------26,632 (apprx 8.5 months--1/3/09 thru 9/24/09)
miles on vehicle--------110,062
UOA by Oil Analyzers:
Overall severity of report--------3 (abnormal)
LAB COMMENTS: Lubricant and filter change is suggested if not done at sampling time; Infrared results indicate OXIDATION is SIGNIFICANTLY HIGH; Base number is below acceptable minimum; Viscosity is SLIGHTLY HIGH; Abrasives (silicon/dirt) are at a MINOR LEVEL; Flagged additive levels are higher than expected for the lubricant that is identified (This does not imply that the lubricant does not meet proper API, SAE or ISO classifications.)

NOTES/COMMENTS:
This is a relative‘s car. Probably around 60% highway, 40% city. Previous OCI’s were apprx 10k miles with Royal Purple/conventional filter, then apprx 11,000-18,000 miles with Amsoil ASL 5W-30/Amsoil EAO09 or EaO10 filters and Amsoil ACD, Amsoil HDD diesel oils. Owner said he’s been changing air filter every 30,000 miles. The 30,000 mile plugs have been in use for probably around 60,000 miles.
At time of sample, I recommended oil/filter/plugs be changed ASAP. I recommended Denso Iridium Long Life (120,000 mile) plugs when his supply of 30,000 mile plugs runs out. I’m also going to recommend some periodical use of LC20 & FP60/FP Plus---LC20 to help keep engine as clean as possible/viscosity in check & FP60 to keep fuel system/combustion chamber clean/efficient.
Owner has been advised of Amsoil’s updated change intervals for EaO09/EaO10 oil filters. However, I don’t see a problem using the filters up to around 20,000+ miles in a clean, efficient engine with 100% synthetic oil.
