Book says not to burn it, just 87 octaine, or will just pinging. But put some in by mistake, and runs better! Around town, anyway - Got a plug that gets black quick, oil, I think.
Yet so old, blow -by must be significant - Would 91 help?
Or would making it into a minisize by leaving it on RR tracks help?

No sir,
Don't waste the money. The 91 is for high compression engines and the trouble with yours is too low a compression . It's time for a rebuild. You didn't say how many miles are on the engine but my guess is quite a few. Take it to a mechanic and have him run a compression test on the engine and he should be able to tell you what it needs. Either a top-end rebuild or a lower end rebuild. If the truck is in real good shape otherwise, maybe a crate engine or one from a salvage yard.

at the starting up, how previous is the battery? After many years batteries have a tendency to "placed on" internally. they could strengthen tiny shorts between the cells, and would even lose voltage by the case to the battery field itself. you could take the truck to an automobile parts save and ask them to placed a load try on the battery. also, have the alternator checked for low output. both exams will be performed without delay and could allow you to comprehend if the alternator and battery are okay to commence with... then you could isolate conceivable circuit drains...have an electric powered multi tester accessible, disconnect the unfavorable battery cable from the battery, set the meter for low to medium amps, connect the leads between the cable and the battery submit, write down the interpreting. Then pull one fuse at a time, recheck your interpreting. at the same time as the amps drop, you discovered a circuit that "would" be causing the problem. bear in thoughts, the clock makes use of a small amperage to save time, regardless of the means off. As you'll locate, there are truly some conceivable motives, yet a methodical study will frequently take position the problem truly quickly...

For an '81 model, I suggest going to you local bone-yard and getting a good engine for it. If it were me, I would put in a mechanical 6.9 diesel.
If you are able to do the rebuild yourself, you can get the rebuild kits and save a LOT of money. Just do it in a clean garage.

You could always try some Lucas oil stabilizer. I doubt it will take care of your problem, but for 10 bucks it's worth a shot.

Your wasting your money putting in high octane gas. It sounds like a dead horse. Time to get a new one.
