Hi.
Since you have so much concern about wear on initial start up,
Maybe you should have a pre-oiler device on your engine...
With this system you can provide oil pressure to the bearings, before even
cranking the engine.

No. I am not concerned about "dry" wear on engine start up.
It is the oil weight of 20 at cold start question. Most engine
wear occurs at the first few miles after a cold start. Is 20W-50
good enough or is 5W-50 better for reducing cold start wear?
This may be a question during winter only. 5W-50 is not widely
available. I am using 10w-40.
Yes, I keep hearing that 20w-50 works fine. 10w-40 has worked very
well for me too. But is there a difference? What is the difference?
What is better for winter?
I know once the engine warms up there is no difference any more. But
the wear happened before the engine warms up. I heard that each cold
start wear equals the wear of 200 miles of driving. I think dry wear
contributes to the cold start wear too. But it occurs only for a few
seconds.
Thanks for the accusump suggestion. That's something I haven't thought
about. BTW, I look forward to hearing your new trip report soon.
