Daustin, Good plan. PreLube with either one by putting a Teaspoon worth directly down the inlet port.
WarWagon, not trying to start an argument, but I don't want people to panic away from atf in the fuel system as a lube and cleaner. I get your concerns, but I have learned the opposite.
Ashless has 2 reasons. 1. Emissions 2. When ash is combined with high carbon and sulfur it forms coke when burned in the cylinder. The quantity of ash from atf is so low in these percentages it almost couldn't be measured. Keep in mind the only thing better than burning atf at cleaning Coke and carbon from the chamber is wmi. The carbon on your Pistons would have been less if you ran atf through the fuel system - that is the reason big rigs do it, along with cleaning the ip and injectors.
Flashpoint of diesel 126(f), atf 200-250. Yes a bit higher. Kerosene varies from. 100-165. So no real concearn in an engine. Diesels run on fuel from 90-290. It's really simple math 50% product flashpoint at 100 combined with 50% product at 200 equals me product at 150 flashpoint. So if he filled the ip with pure atf, and it washed through and couldn't ignite (it will but for example) when the diesel fuel behind it does ignite the 1 or 2 cups of Atf that gets pushed back to the tank will mix in with diesel and wash out to a barely readable level.
I can't see any negative from any of the additives you mention, in fact I see they would help the ip.
Like you mentioned the 1970's design was used. No ulsd containing Methonal up up to 10% by volume. That crap destroys seals, and counteracts lubricity at an alarming rate. Just as bad is the keytones used as a cosolvent so the two dissimilar liquids will stay in suspension with each other.
No one is allowed to sell atf as a fuel system cleaner to you. It works amazingly well, safely. It does not meet emissions standards, so it can not be sold AS AN ADDITIVE. However, as part of a mechanical treatment in maintenance or repair it can be used legally. Just like the Gm upper cylinder treatment used in gas engines. They have to print on the bottle not to add it to the fuel tank. It has to be administered to the vehicle through a vacuum hose while in a controlled environment not on public hiway.
It's a tree huggin action plain and simple. The plastic to oil/fuel company I've been working with the last few years is giving up the fight to sell a cut of the product as additive because of the legal loopholes additive companies have to jump through. The epa actually uses atf as a treatment as the benchmark example. They state the concearn of class 7&8 trucks using up to 80% atf as fuel like they did in the gas crunch and contributing to smog/acid rain from the sulfur content.
I want people to use a CDR instead of venting becuse it adds to smog. I don't want people to use atf or wmo as a fuel source bcause of smog. But IDI diesels using it as an additive or in this case a cleaner for getting rid of the aluminum oxide he will have inside the ip,and a prelube, it's long term will be positive for his parts and the environment.
