Did My First Oil Change Today

Whats wrong with the 20-minute oil change? Its ALL THE SAME! I was one of those "Its gotta be Synthetic" people but as soon as I realized it did nothing but SLOW my car down and cost twice as much, I gave it up and just changed my oil sooner than later. Remember 90% of engine damage happens within the first few miles of your drive, let the car and oil get to temperature before you go flying down the highway and you'll be good! O yeh how's the dipstick on the G37, the G35 had a terrible design so its really impossible to tell.

Oil Questions Help
Everybody seems to have endless "Oil Questions" on every car user forum in existence, many forever searching for the "best erl", some magic answers, etc. 
See here for almost anything you might want to know about the slippery stuff that's in every car's innards:

yeah good point...its proven that synthetics like amsoil and Mobil 1 are made of more stable equally sized particles that bind to the engine, lube better, help there be less friction and less heat in the engine, etc. Even Royal Purple has done test to show that their oil has the engine running at cooler temps, cold starts are smoother, few more HP when switched to Synthetic at later mileages, etc...etc

There are plenty of articles all over the web about the molecular differences between the oils. But, to simply answer your question, pretty much every oil company engineer will tell you synthetic oil will hold contaminants in the center of the oil molecule, away from the edge and away from the contaminant doing any damage. Conventional oils do not have this ability. That is the reason oil companies say synthetics "flow" better and use of a synthetic oil will lead to less internal wear.
Concerning your used oil analysis, please contact the companies who perform oil analyses. They will show you what they have learned.

Also, I've seen used oil analyses printouts for conventional oil and for short oil change intervals, they perform just as well as synthetic.

I would rather run synth for longer intervals than dino on shorter intervals. Plus there's not as much waste and time spent under the car. Been doing my own oil changes for years and we have a tribologist in the family.
I would stay away from Purolator filters. And Fram. Search oil filter tests and read for yourself. That before someone says 'prove it'. Often times, OEM filters are the best option.

I am not trying to be contrary, or a jerk or someone just trying to **** you off. But, I found a few oil filter tests on the net and I didn't find anything that would cause me to stay away from Purolator. I did find one site which noted Purolator ties a string around the pleated filter to keep the pleats in line and one filter had the string dig into, but not tear, the pleats. That was the worst I found. On the other hand, most tests said the Purolator anti-drainback valve was good.
What am I missing in that you recommend staying away from Purolator? It seems the Purolator One at less than $5 a filter with the synthetic filtering element seems a pretty good buy.

I plan on following the MFR's guidance on break-in and change intervals for the first few thousand miles then I'll start sending samples to Blackstone for detailed analysis. They can tell you if you should lengthen/ shorten your intervals and how your motor wears running any given lubricant (dino vs syn). blackstone-labs.com

Isn't 0w-30 the same weight as 5w-30 but flows better when it's really cold? I'm curious because my car will see -30 degree mornings occasionally all winter long. That's 70 degrees colder than it is right now at 40 degees. BRRRR.
