Oil Change video


Kitti Politi and I shot a new video on oil change information today, and evidently I got the coffee/sleep ratio pretty close, because it looks pretty good, I hit it in one take, and I did it straight off the top of my head with no script.  Kitty, who is relatively new to the team, had not previously seen my idiot-savant capability to transform into the caffeine fueled ‘abominable showman’, a performance honed over thirty years working on Corvairs and giving more than 600 public forums on the topic.  She thought this was pretty cool. As long as the Coffee/air ratio stays right at 12:1, we will have many more videos to come.


Kitty  emailed it to Ken Pavlou in Connecticut, and Volia! just like magic, Ken makes a professional video appear on my Youtube page an hour later. Use the link below, and look under the “Operations” playlist:

About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.

    I am very glad you are making YouTube videos. A video showing the process of changing the oil would be very interesting as well. Next time a corvair plane is scheduled for an oil change, make a video of the job!

    Agreed. Would love to see an action video. Like Experimental Aircraft Porn.

    Can we get a link to your recommend oil filter cutter? There are quite a few options out there! Also, I assume you use Blackstone for oil analysis? Or is someone else more familiar with the specific thing to watch for in a Corvair flight engine? I really appreciate the service you provide with this blog and the videos, thanks!

    I have the Summit Racing brand of oil filter cutter. It works fine for me:
    I believe the one William shows in his video is:

    Hi Joshua,

    I’ll let William answer the “oil filter cutter source” part of your question as I would find that helpful as well, but the analysis part is here: https://flycorvair.net/2018/02/16/corvair-oil-analysis/

    Affordable, and provided by a Corvair builder to boot. Cheers.

      Thanks, Tim! I’ve been following the blog since about January of this year, and am working through the old posts, but haven’t gotten close to 2018 yet! Appreciate the link.
