For my own peace of mind I decided to get my oil tested at Blackstone Laboratories. In doing so with an engine (seemingly fine) it allows you to find any potential problems before they become catostrophic. It also may conclude (as in this case) that your engine is healthy and not showing any signs imminent failure. A very insightful preventative maintenance tool. Without knowing for sure its easy to imagine a stock motor like mine being pushed beyond its capabilities with larger turbos (GH) on Methonal and Nitrous. Although a vigorous maintenance schedule is performed how do we know if it's really ok? Is my tune maxing it out? No. I'm pushing 19 psi boost and there's room to turn it up. The tune right now with Meth has my spark at 18-20. Knock sensors are not allowed to add more timing past 3k rpm. Believe me...they will. They are more than happy to add, add, add. Brad shuts them down to try to keep timing and torque in check...a small piece of the puzzle and effort to keep this car on the road and not in the shop. The knock sensors flatline to 0 when going WOT. The tune itself has not changed since the introduction of Nitrous. I have increased meth volume to even out my fuel pressure but that's it. No tune revision needed. I'm rambling. Well here it is. An oil sample of my Royal Purple 5w20 w/K&N filter at 1,100 miles. The car has 74k so shes still slightly young. Now yes, 1,100 miles isn't a lot but it's nearly 6 months old, changed before I added GH turbos and nitrous. Many, many datalogs, track runs, datalogs with nitrous and track runs with nitrous all in that sample. Check it out. I'll be adding regular oil sample testing to my maintenance list. Next up will be PTU, RDU and Transmission oil sampling.
