Hi everyone,

I am not too familiar with UOA and just wondering if this is a sufficient enough test:

I run a car on a race track (non-competitively) and wanted to know how often to change the oil.
I use Shell Helix Ultra 5W40 on a 6A12 Mitsubishi motor with bolt ons.

I'd ideally run about 8 track days a year and would like to have annual OCI (which would result in about 1,000 miles total I would expect)

2003 Mitsubishi Diamante 6G74 3.5L. 5 Speed auto. 155,000 miles. Shell Helix Ultra 5W40 at 6k OCI

Seems pretty barebones, but it should be okay for estimating OCI.
