First UOA done on my V. This is the longest OCI. There were at least six other oil changes including this one (I can dig through receipts to get exact count if important). All units are km (even if it says miles). Also, I sent the sample to two other labs and will post those results once received.
Several concerns:
1. I need oil for summer track days plus normal use. Should I continue this one or change to another one? I was looking at RL 5W30. Should I change after every track event?
2. My mechanic wants to swap the transmission and rear diff fluids at the end of the season. Thoughts?
3. How would I be able to tell if there was any contamination in grabbing the oil samples? I had the mechanic take about 700 mL, then I split that up into 3 x 3oz for sending to three separate labs.
4. I also need to clean the current container for the next sample. How do I do that without adding even more potential contaminants? I was looking at getting a vacuum pump and drawing through the dipstick holder. Thoughts?
5. My mechanic recommends just switching oil every 5k km (3k miles) regardless of UOA. His argument is the cost of any potential contamination is higher than any expected gains from longer OCIs.
6. I've started using Redline SI-1 every fuel up (about 2oz / 10 gal fuel) after two shock doses about 3k km apart before the last oil change. Is there any way to verify it's doing anything? My understanding of everything we do here is that because we have no ability to do controlled samples it's all just a grand delusion.
