Make up oil-----------added & removed 16 ounces between miles 31,894 & 35,144 (dipstick read issue)
Engine oil capacity---5.5 quarts
oil filter----------------Amsoil EAO57 (Amsoil replaced with EAO51, now with 15,000mi/1yr recommended change interval)
air filter----------------Amsoil EAA (100,00mi/4yr warranty, installed 5/9/08 at 24,011mi, cleaned at 35,144 miles)

Miles on filter---------25,098 (64 months---5yr,4mo)
miles on vehicle--------39,872
UOA by Oil Analyzers: LAB COMMENTS: Infrared results indicate OXIDATION is SEVERELY HIGH; Total Base Number is SIGNIFICANTLY LOW; Change oil and filters if not done when oil sample was taken.
Overall severity of report--------4 (critical)

NOTES/COMMENTS:
Denso long life Iridium plugs. Aprx 65/35 highway/city driving using mostly feather foot. Many short 11 mile trips. FL weather. No warmup time.
Plan to chnge oil/filter immediately with Amsoil SSO/EA oil filter. Limit future change intervals to 2 years, at current truck use rate.
