Engine oil

Manual use says 30w, that means in hot old cold oil acts as 30W? Now Can I use 20W-50 High zinc Kandel oil in my Corvair with hardened valve seat?
If 30W is fine then 20W-50 should be okay too?

Didn't the Bradd Penn guys recommend 20/50 during their talk at the convention? I thought that is what I was told. I'll just keep sourcing Joe Gibbs or Bradd Penn in 10W30 myself. 20W50 might be okay in my turbo mind you.

Now that my turbo engine is broken in I went to Rotella t-6 syn 5w40. That covers cold starts and hot turbo oil temps.

10w30 unless you are just hellbent on starving bearings while the slow heavy oil tries to reach them on cold starts. Also if you want to firmly believe that 20 to 30 minutes of lifter clatter is just “normal’for a Corvair 20w 50 is awesome. Valvoline racing 10w30 and my car is happy. Loose tolerance, worn out engine and racing engines call for thicker viscosity. A well built tight engine does not benefit from thick oils. You are doing more harm than good. 20w50 is “hot rodder” oil for engines built “loose” to spin fast and make power. That molasses fills the gaps. I’m no expert though and so begins the threads of oil vs oil and owners vs owners.

Does anyone here know the definition of "cold start"? I've always thought of it as 32F and below but I'm probably wrong?

They didn't include 20W50 in the pour comparison because they had to go home for the night. GGG

The Protection Zone on the chart is different for different engine families. For the example shown, 20W50 doesn't begin to protect that engine properly until the oil temp reaches 250 F and oil temp generally lags behind engine temp on any engine.
The F numbers on the chart look a little strange, because I added them myself.

I have been running the VR1 10w30 after breakin since I built my engine about 15k ago. I’m no oil expert and don’t claim to be but after 412,000 and going strong with my Toyota Tacoma, I’m valvoline biased. Yes, I have heard before that oil is oil but I only use one brand. Valvoline all-climate in my truck and Valvoline racing in my Corvair. VR1 is pricey but wipped out cams are way more. Good luck, the oil debate may be the longest debate running. Do some research and pick what you feel comfortable pouring in. Make sure to read up on Richard1 posts. I think he is most qualified to answer.

I recommend Amsoils' 15W-40 "Heavy Duty Diesel and Marine Oil.(stock# "AME" ) A Navy buddy recommended it because our Corvairs are air cooled, back in 1981.
I've never looked back. It's the ONLY oil I've used in everything I own since back then. It works super in everything we own, including: my snow blower, 3hp push mower, my zero turn riding mower. We used it in our '95 Buick a while back and got almost 400,000 miles out of the original engine. The car had 75,000 miles on it when we got it and drove it until it had over 360,000 miles on it. Since it has a 25,000 mile drain interval, that means we changed oil only 11 times in 13 years!!!!
When a mechanic friend pulled the engine to investigate a "Ticking noise", we checked it over good. Pulled a head and NO RIDGES!!! You could still see some of the cross-hatch pattern! The "tick" was a roller lifter gone bad. The other 11 were like new. Since it was cheaper to just get another engine out of a junkyard than to fix the lifter/cam, do a valve job and replace the timing chain, we went that route.
I've used nothing but "AME" in my corvairs for over 38 years with nothing but
absolutely FANTASTIC, SUPER, STUPENDICE results!!!! I absolutely, positively, will never ever use anything else!!!! EVER!!!!!!!!!!!!!!!!!!!!!!! What can I say? IT WORKS!!!!!!!!!!!!!!

Since I didn't see an answer to this -
Cold start is when the engine isn't at operating temperature. First start in the morning is cold start even if it's 70 degrees outside. Obviously it is worse the colder it is. Operating temperature on oil is 220+ so less than that is "cold".
