Vehicle:
2006 Scion tC
Oil:
Amsoil AZO 0W30
Oil additives:
None
Make up oil added: Three (3) quarts was added total. I added half a quart post the first sampling @ 7,500 miles and added the rest of the bottle @ 9,000 miles.
Engine oil capacity:
4.1
Oil filter:
TINY Mobil 1 (much smaller then the OEM filter)
Air filter:
Whatever cheap piece of [censored] air filter is on the aftermarket "Cold Air Intake" that's on the car. Thinking of eventually replacing it with an Amsoil cone when the time comes.
USE: Mostly highway/city @ 70/30. The wife does roughly 50 miles daily round trip to work and back and i beat on it when she gets home while i do my errands, ranking up another 50 miles or so while bouncing off the rev limiter, so the miles rack up quick.
The VOA of this oil can be found here: VOA of the AZO from the same batch
I decided to go ahead and change the oil after i sent off the sample because i thought the TBN would be lower but now wish i would have kept it in use and ran up to 12k.
I changed the oil with some more AZO from the same batch / case. I replaced the PCV valve and hope that will help the oil consumption. Only time will tell.
Thoughts? Comments?
