Hi guys and gals. Need to change the oil in an old 392 V8 petrol International engine (not a 392 Hemi, I wish it was though.). What is the best oil to use??? HC.
Does it have a filter? I think the zinc issue is primarily for breaking in new engines, but someone else will have to chime in with more info. Beyond that, it probably ran SAE 30 then, if it has a filter a multi-weight detergent should be fine, if no filter then stick to SAE-30.
I have always run 30W in mine. I live in high heat desert so no need for multi weight. I have IH engines since the late 60s..quite tolerant..more like industrial/agricultural motors. Low reving..high torque..
Yeah it has got a filter rustynewyorker. Docc, you said you live in high heat desert. I live in South Australia and the hottest we get average about 42 degrees. but thats only for about 2-3 weeks. Would 30W be fine to use in my part of the world??? Thanks, HC.
It's kinda unfair since the whole oil discussion has been beat to death and most folks are tired of the question. In the end, how do you choose whose advice you are going to take? What the hell. I'll play. ... I'd run a diesel blend like Rotella 15-40. It more than meets any possible requirements your engine will have ... temperature, filter, etc. etc. If you want to be paranoid, there are plenty of guys who will help you right along.
I don't mean to bore you guys but this is what the H.A.M.B is for. I'm not familiar with this engine and don't know much about these International V8's. So I come to the H.A.M.B we all love for a little guidance from the more experienced and more knowledgeable H.A.M.Bers . That's all. Thanks, HC.
You can cover your **** with both hands by using a multi-viscosity oil. Just use a good brand like Castrol or Pennzoil. If the engine has cork gaskets, stay away from synthetics because the synthetics have a tendency to leak through the cork.
"Thanks a lot Andamo. I will do that i reckon." HC, you seem a little offended by my telling you that a lot of folks are not going to bother answering your question. I did answer it though. And, I gave you good advice ... which you have chosen to ignore in favor of Andamo's recommendation. That's my point. How did you determine his advice was better than mine? (By the way, you CAN run Castrol, Pennzoil or just about any decent oil in your engine without hurting it.)
Hoop I think Heyycharger didnt like your at***ude, I didnt ether. Heyycharger that old IHC will like 10w30 or 10w40 rotella , I work for a major lease company and years back when we had IHC gas engines we ran 10w30 rotella in them, so thats what I have been running in my 327 Chev. I like the fact it has plenty of ZDDP in it.
one more answer. I'd run VR-1 Valvoline which according to the company STILL has everything in it to protect any flat tappet engine. With that I'd add SAE 30 and not a multi-viscosity. Reason being IMO it's only as good as it's lower number. I'm building what should be a strong sbc and have always used Valvoline VR-1 20-50 but I'll be changing to SAE 30 when it's built
motor oil is motor oil it all comes out of the ground not all true . epa has really hurt oil . all the good stuff has been taken out for epa standards . there are lots of posts on this subject ! VR-1 has the most "ZDDP" , RED LINE also . the older cars use the "zddp" for cam life . just my research .. steve
The International 392 is not a Chrysler engine. There is no relationship between it and the 392 Hemi: it's a totally different truck engine. I have a 392 in my 1972 International Travelall. It has been rebuilt and has used Mobil 1 ever since the break-in was finished.
I thought everybody knew by now that even Rotella has greatly reduced Zinc content these days. It was good to use for awhile but that time has come and gone. The EPA got to it just like they did regular motor oil. Get the Valvoline VR-1 racing oil. It's still good.
If the motor is old as you say, I would run a "high mileage" oil and I also add Motor Medic to give it some new life. As for Pennzoil, I used to run that until a tore a motor down and saw all of the carbon build up it develops in the oil valley.
OOOh, sorry. I have no idea why I wrote Chrysler. I did that when I actually thought it was a chrysler and someone corrected me. Since then, I've been calling it an International V8 but I don't know why I called it that. A bit sleepy I think. HEH. Thanks to all for the Advice. HC
Hoop-in-jax, I did get a bit frustrated when you wrote that and your first post but look, we all have our own ideas therefore giving people like myself who start these threads a wider range of, in this situation, oil to choose from. In the end of the day, we all love the same thing the reason why were here is to help everyone out as much as we can. Hoop-in-jax. "HC, you seem a little offended by my telling you that a lot of folks are not going to bother answering your question. I did answer it though.

How was I meant to know if you were serious or not if you talking in that manner??? All is cool. HC.
Just a thought , the ZDDP issue is in the U.S.A. HeyyCharger is from Australia. Has the ZDDP been reduced worldwide or just the United States? If it's just us then the brand of oil would'nt matter.My $.002
I live in Hot *** Louisiana - I run VR-1 20w/50 with a half bottle of ZDDP. As soon as I run out of 20/50 I think I'm going to switch to 10w/30. Don't ask me why - i just think 20/50 is too thick for my motor.
