Well, I'm sure many of you guys know that I have been running Redline Synthetic Oil from
3600 miles on my Z. Well, last week, I have just turned over 19,000 miles (19,275 to be exact). I did oil analysis for EVERY Redline Oil changes from
Blackstone Laboratory.
Take a look at the very last oil report:
I don't usually share the oil reports because every driver is different. Each oil report will be different due to the driving condition, weather, driving habit (of the driver), roads being driven on, etc etc. But you should def do the analysis for your
OWN guidance. These guys will guide you perfectly when to do next oil change. In the beginning, they actually asked me to keep it in 5xxx miles and now as you can see, they want me to go upto 7000 miles! The testing costs about $22 (and I usually ship via USPS Priority or UPS for quicker shipment).
Also, during
my previous oil change (at 14,xxx miles), I used the
Purolator Pure 1 filter and looks like it did a great job. Heck, I even did
4 dyno pulls two weeks ago, back to back with dirty oil/pure1 filter!

This time (however) I used the K&N HP-1008 (due to some leftover filters in my garage) and it'll be interesting to see how well this filter does against Purolator Pure1. The pressures on K&N now

As for getting oil samples, I usually take the undercover shroud off first. Then go for a
very spirited drive
Bring my oil temp to about 220 - 225 F. Then, put the car on ramp and get the sample from the middle (not the begining oil. Wait about 5-7 seconds). Here's their official oil sampling guideline:
Gas Sampling
I very happy the way they guided me and glad that my VQ is in good shape. Now, time for me to go out and do some powerslides!
