i wouldnt use anything less than 5w-xx.
you may be burning some oil until the oil reaches operating temps if you use mobil 0w40.
you ll be fine with a strong 5w-xx oil.

Huh???? You do realize your comment makes no sense right?
The oil is a 40-weight (albeit, a light one). But it has superior cold flow to a 5w, 10w, 15w, 20w 40-weight oil.
It doesn't flow like water at -30...... It is still heavier than spec for a 40-weight at any temperature below 100C.

What's done to it?
I'd say yes, it would work well.

i just assumed it s a high mileage stock 65 engine and he is switching from 15w-40 to 0w40. and i missed "loc:texas". so he isnt seeing low temps. sorry for the misdirection

Hey, no problem. It'll be lighter at start-up temps, but still is a 40 hot. I figured you may not fully understand the grading system, which is why I pointed out what I did. Wasn't trying to be rude, so I hope I didn't come across that way.

How close is it in price to the 0w40? 10w40 seems like such an obsolete grade.....

Here it`s REALLY cheap,as far as synthetics go. It`s around $4.50 a quart at Walmart. Supposedly has 1100ppm of zddp according to Mobil. Seems like a good weight for a 60s era muscle car.

Ahhh, OK. I think there is only a dollar difference between the "regular" M1 grades and the 0w40 up here. I've been very happy with how it works in Ford Windsor engines.

Man I wish Walmart would get the 0W40 in the cheap 5 quart jugs,I`d try it in a heartbeat! Unfortunately they only get it in the $9 dollar single quarts :^(

I wonder how well it will work with the flat tappet cam?
Would a diesel oil with higher zinc levels be preferable?

The Professor recommends Quaker State UD. Either 5W-30, or even 10W-30 would be fine in the Texas heat.
It would be a good choice with a stock engine. If you have a modified cam and valve train I would move up the ladder a tad with a zinc fortified oil.
I am still running a 20w50 full synthetic in my stock 318 and it slurs a tad bid turning the starter over. But the 25degree weather is not hampering the oil pressure yet.....

i would use a good dino sometimes synthetic causes leaks on old engines.

Old wives tale. Sometimes a good cleaning syn can clean out an engine that already had a leak that had gunked itself up and sort of resealed it. I have run syn in 30 year old engines with no leaks. My 86 chevy is running rotella 5w40 synthetic right now and does not leak a drop now that I replaced the valve cover gaskets that were rock hard and cracked.

Id say that any oil of todays specs should out preform any oil back then zinc or no zinc. mobil hm sounds like a good match. or any other hm oil.
M1 0W40 is a great synthetic oil for your application. You could do a UOA at 4K and test it against a mineral like GTX 10W40 and pick the winner. Most people don't realize that syns & mins perform similar in real world applications.

M1 0w40 is surprisingly robust in this department actually.
