Hello all!!

Starting the process on my Z06, which I've had since early 2004 and is my second and only other car. She's stock with the exception of a K&N cold intake I put on years ago. It's been taking me forever to bolster my main project (see 2018 GMC Sierra 1500 6.2L V8 - Starting from scratch), yet been itchin' to get the ball rolling on the 'Vette, too. Since the Snake Oil has come out, I've been anxious to get that in the oil. It was due for an oil change, anyway. So, I ordered enough Snake Oil to do both cars.

I've historically averaged low 20's (23+) on the MPG's, but have noticed a drop to around 18-19 mpg, lately. I account this to a lot of idling. I've been very busy of late and haven't had much time to exercise her much. So, I'll fire her up and let run for a bit at least once a week and for short trips as a grocery hauler. lol!

Step one:

- I did the WD-40/Carb cleaner treatment in the oil and let it run for about an hour.
- Drained the oil and refilled with fresh and new filter.
- Applied Ron's amazing SO and took it around the block to test for leaks

When I got back from the test run, parked it, I noticed the engine was running smoother than it ever has!! There is something truly amazing going on here! The loudest part of the engine was the fan! I just ordered some SO treatment for the fuel and will report my progress. Also, applied Snake Oil Coolant treatment to the radiator....

I don't like taking the Batmobile (as I call her) to the airport when I leave for my trips. I'll be in and out for the rest of the week and not gone for over night. It will be my daily driver for the next few days. She needs to get out and run, anyway. This should put about 40 per day, for the next few days, at least. Looking forward to positive results.

Next up:
PCV delete
SO in transmission and diff.
Bifilar coils
...and of course...the Groove!

Upgraded coils, wires and plugs via the Greg method and Granatelli, but that will have to wait, since I'm tapped out on the funds.

Closely following Gene B. and his '88 Vette. Good to see a fellow Vette owner!!

Actually, TracyG got me thinking about ignition improvements - if anyone deserves the credit, it's him! he turned me on to Torquemaster and Granatelli, and since they worked/improved things as advertised, I've been spreading the good word.
And that's what anyone following along should take away - I "shill" for stuff that I've seen/used/I know works - not because I get any personal benefit from things, because you will/do, and we all will as well with cleaner air/water, more $$ in our pockets, more time to spend with friends and loved ones because of less time working/paying at the pumps...

:-) Thanks, Claudio!

Looking forward to see what results from all these mechanisms.

Roger that, Greg! That's why I've taken so much of your advice and guidance. Never thought you had any ulterior motives. We're all on a mission. Let's git 'er dun!
