So I just got my '13 TL SH-AWD from the shop where all of the fluids were changed and any sort of preventative maintenance (timing belt, tensioner, water pump, t-stat, belts, etc) performed. The oil change was with an OEM Acura filter and 3.5qts of M1 5W30 with 1qt of HPL Engine Cleaner 30. I plan to run this for around 2k miles and then switch to HPL PPCO 5W30. So being a newb here, what analysis or what testing should I do have I run this 2k oil change with the above fill? So will that be the time to send off a sample to Blackstone? I should cut open the used filter once another OCI is done?
