I was just kidding. ;-) My next fill will likely be 0w-40 (the mythical magical Mobil 1 stuff).

Hilarious. Oh no - 40's! Time to grab the 20 weight! I must have a long sleeve T-Shirt around here somewhere.
 
It might hit the 60's here soon. Guess I need to get that thick 5W30 out and go with 0W30

That wouldn't be a bad idea. I mean, why would you use that in any car given what we know about modern multi-vis oil? Ease of starting and less wear would be worth it right there.

If i remember right he got it for very cheap or free.

That said, how will the 30 cause more wear that say a 5w30?
 
The 30 might cause a bit more wear in a northern climate, but I run it through the brutally hot Gulf Coast summers with no hesitation at all. When you have an overnight low of 80 degrees, the "5" would be useless.
 
It the 5w30 would still be significantly thinner at 80 degrees, if you call that "useless" then OK.

I've been helping out at a workshop for the busy period leading up to Christmas. They have Durablend and Synpower to use where required. They also have bulk Maxlife 20w50 for old or high mileage cars out of waranty. It goes in everything and anything that could benifet from a high mileage oil. High mileage oils only come in 50 grades here so there is no other choice.

I got about 70 gallons of hd30 free last year. Lowest temps here so far were 19 F and no trouble starting yet. This stuff has performed better than 5w30 and 10w30 in my Caddy so far. Seems to run about the same as the T5 10w30 in my last OCI.
The Plymouth is only used in warmer weather.
 
SS1970, use with confidence. Don't listen to the internet hysteria about thicker oils. Because of all the Pennzoil conventional 30 and 40 wts. I got almost free, I am running 40's from May-Nov, then 30's to help with out with our brutal 60 degree winters from Nov back to May.

My 97'Chevy pickup has not even noticed.

Based on the temps up here annually and the specs in my Caddy's owners manual, I could use this HD30 all year. Next year, the '63 will get it also.

Put some sae 30 or 20w50 in a Dixie cup and put it in your freezer and then observe it's visual thickness and tell me if you want that kind of molasses in your engine.
 
1996 Ram 1500 5.2L (318)

Using a mix of 0W-20 (3 and a bit L) and 20W-50 (1 L) during startups at -30C Air Temp I get pressure within a fraction of a second to 60 PSI which settles to about 50 PSI @ 190F and stays there.

The "3 and a bit" comes from a 3L 0W-20 fill, 1 full L 20-50 and then top up with 0W-20 to cold reading on dipstick after an oil + filter change. I'd guess about 2/3 L.

All Mobil1

When I bought the truck … I don't know what he had in it, but 5w30 conventional is the cheapest around here … it would take 2~3 seconds to get an OP reading at all on cold (below 0F) startups, would go to 50 PSI and stay there.

I would normally run all 0W-40 but when I did my last oil change I was in British Columbia Canada and 0W-40 is impossible to find there (although I wasn't in the Lower Mainland); too warm in winter I guess.

I did not want to go with all 0W-20; I wanted something a bit heavier in there for running Overdrive on the highway at 60 MPH+. It wants to kick into OD at about 53 MPH but I disable OD unless I'm on the highway.
