    Your right N8N. I drive about 5 miles each way to work. Thankfully the windwings and vents on front of car definitely keep air moving. Its not so bad w/o the a/c. But.... before another summer comes on it will have it..whether or not it will be able to get out of its own way..

    It should be noted that on vehicles equipped with an idiot light, rather than an oil gauge, the threshold is somewhere near six PSI.

    You're in great shape.

    A synthetic oil will likely thin less at high temps than a conventional oil, if you plan on really driving this car hard. however, on an unrebuilt Studebaker, it'll likely leak like a sieve...

    you could also add an auxiliary oil cooler if you really wanted, but again, only if you plan on driving the car really hard. I'd be more worried about operator durability without air conditioning at 106 degrees!

    The oil pressure is fine, don't worry about it. If the ambient air temp is above 100 degrees, the oil temp. is probably in the 220 to 230 deg. range which causes the oil to thin considerably. Bud

    Shop manual suggests 40 psi oil pressure at 40 MPG in high gear. Yours is like new.

    You are within a good range. I wouldn't worry too much. That is very common for a lot of engines. Especially if it has not been rebuilt.

    OIl for high temps

    On my 59 when the temps get above 106, the oil pressure drops to around 10-15, when the temps are in the 80s and 90s it stays around 20. I'm currently running 15w40 Rotella in the car. Is this normal at the extreme temps to run this low? When running down the road, its running about 40psi at 40mph in overdrive. Thanks in advance.
