Mobil 1 has a new 0W40 full Synthetic Super Car oil; I have been running it in my 440 and have very good oil pressure and I like the fact it lubricates very well at start up especially with my roller camI have some 20W-50 VR1 “High Zinc” in my shop and am planning an oil change. Is this too heavy?
Information:
Flat tappet 340
High compression 12:1?
Older engine oil pressure was on the lower side if I recall correctly maybe 30 psi but don’t recall what oil was used.
Lives in Phoenix and it’s getting HOT!
If not what do you recommend?
Thank you!
15/40 Good stuff, least back in the 80's. Ran it in everything from Mack trucks, Cat dozers, fork lifts, even in the salesman cars. Salesmen beat the crap out of those cars. Only one flat chevy cam out of 10. Most had over 100K when we ordered up a new fleet. Macks 400K before rebuilds.Delo 400
I currently run Brad Penn 30wt in my 360 dart sport. Works great. I recently purchased schaeffers 30wt. Have heard good things about this oil. What do you all think?Ive been using Brad Penn (Penn Grade HP Oil) 20W-50 synthetic blend in my 3 cars for years now. No complaints.

Yup...and everyone continues to miss the point. It's not about "you" !
ya THINK?
The past is a little gray for me as it was 4-1/2 years ago AND another lifetime. It is indeed possible that I used the 20-50 VR1 just prior of shutting down for restorative work. I recall seeing “low” oil pressure from my inexpensive electric oil pressure gauge but never documented it nor verified it that I can recall with an accurate hard lined pressure gauge.We can keep saying what "we" use all day long here. The only real question is..."what does the OP need". He has yet to declare what he WAS using and the need if any to switch to anything else !
It's fine. Nothing wrong with a little extra viscosity.I have some 20W-50 VR1 “High Zinc” in my shop and am planning an oil change. Is this too heavy?

When we share our experiences, it gives him valuable info. It's passing on knowledge and real time use of different oils...and everyone continues to miss the point. It's not about "you" !
I get that, but everyone saying what THEY run meant nothing up until the point that I wrote that! The OP had yet to tell anyone what he was originally running, when he asked about "switching".When we share our experiences, it gives him valuable info.

On one of my older 340's years ago, I ran 10W40, to 100,000 miles, then changed to 20W50, until 175 miles, then went to 50W, until I blew it up. By changing the oil viscosity as the motor aged, it kept the oil pressor up as needed. The reason a good oil gauge is important. I run 20W50 on my other 340's I use today. They have around 75,000 miles on them.I just changed my 360 out from 10-30 to 20-50, oil pressure with the 10-30 would bottom out in gear when warm, now I hold steady at 10-50 pounds idle to under load. For reference its a mostly stock 1973 360 that as far as I know hasn't been rebuilt, so my guess is the bearings are pretty loose. It just depends on how worn the engine is, but if it's mostly stock I'd say your fine, especially with the Temps your working with
Every app. is different. There is no one answer. A all-out race car, I would use a thinner oil, as you say, but I would also use a High volume oil pump, which would also mean a deeper pan.The 20/50 will run fine. It's not what I would run or recommend, but big whoop. I know this much. Every single person (and that's a lot) I've ever seen talk about 20/50 online or in person says they've gotten great service from it. I had some, I tried it and didn't like it. But that doesn't mean you'll have the same reaction, so run it. It certainly won't hurt anything.
