I went with Brad Penn 20-50.

Yours is the second recommendation I have had for Driven, maybe next oil change.

At least Driven isn't GREEN...

I used Brad Penn for my initial fill / Dyno run and now switched to Driven.. we'll see how it fares.. Be in the water for the first time this weekend..

The easiest place for me to tap an oil temp gauge is off the outgoing port of the filter head. Is this still an adequate place to tap in to or have things chilled by then?

$11 a quart. Yikes.

$5.45 a quart: http://amzn.com/B00DJ4FIPQ
Sometimes Oreilly's and Advanced has it cheaper.

Still waiting for someone to prove or even think lubrication issues using this.

Valvoline VR-1 racing motor oils are recommended for engines burring gasoline and full or partial alcohol fuels in track and street service
Use in any car, light truck, van or SUV where API SN is recommended
ZDDP additive provides tough anti-wear protection
Enhanced with friction modifier to improve horsepower
Formulated with enhanced anti-foam system

That is still one fantastic conventional oil. Always does real well in tests. One of my go-to choices.

I'm hoping to be able to extend my oil change intervals by changing the filter regularly
then sample / change the oil only as needed...

I Have switched every thing I own over to Rotella T 15-40. I own a excavation company and all the equipment we used Rotella all the time. I noticed one day I was cleaning the funnels I used with brake clean (the good red CRC) and it wouldn't rinse the oil out with out wiping it in between spraying the brake clean. Later that day I was doing the oil change on my car and went to clean the funnel with Mobil 1. No wiping needed. Brake clean washed it clean in 1 spray. Since that day Rotella T in everything, Boat, equipment, car truck and even the Race Bikes and lawn Mower

Rotella is a Great idea. The liberal bureaucracy has not gotten to diesel oils yet and screwed them up..
