What did you put in it's place?
Most engine maufactures list not only a viscosity but, a performance? level SL, SM etc.
The only straight 20 weight that I've seen lately is Traveler brand sold at TSC. I think its made by WPP. I thought about using it in warmer weather in my wifes Honda but decided against it because of the supposed superiority of 5w20's. I may reconsider.
I look forward to the UOA.
I just put straight 50 in my lawn mower after draining the 15w40 and it came out like water.

In Scandinavia I used them as a winter lubricant in VW, Porsche, Benz, Saab V4 (Ford Taunus), Opel, Volvo and etc. vehicles with great success
About then (mid 1960s) I commenced using HD (now known as HDEO) lubricants in most engines after carrying out engine deposit control research for Caltex-Chevron
In the correct application 20w-20 lubricants were/are great performers

Yup. My Father-in-law used 20w-20 Pennzoil exclusively in his vehicles for maybe 40 years with excellent results (Idaho climate gets pretty cold AND hot). I nearly started a family feud when I came along and switched to Quaker State 10w40 Deluxe in my new bride's pickup. Yowza! What a row that was!
He probably still has a few cans of old stock Pennz laying around; I'll have to scope it out one of these days.
