That is still a valid thing to do with todays "low sulpher" fuels. I actually use "Opti-Lube" in all my diesel fuel tanks. Though I have been known to add a couple quarts of ATF or straight 30w to a full tank of fuel. When the industry first went to the low sulpher fuels we lost over 300 injection pumps at Metro transit. They basically tore themselves apart ! It was not good !
Actually "Opti-Lube" beats anything on the market. It is the very best diesel fuel additive out there. Independent studies prove it.
Injection pumps went down in every industry because of the lack of lubrication in ULSD. Yet oil companies and fuel suppliers would swear their diesel was safe to use. Several companies would not warranty injection systems on new machinery if a quality diesel additive was not used for lubrication after they had several injection pumps go bad. I have seen injectors on tractors trying to stick and the engine ran with a miss. After pouring a quart of ATF in the diesel and continuing to run the injector would clean itself and run properly without a miss. Bottom line is todays diesel needs some form of lubrication!
Power Service is acceptable additive. It is readily available at most truck stops and stores. It is not as good as Opti-Lube as shown in independent tests but it is more available. A lot of truckers wouldn't use anything else.

Say again?
No, it is just very high detergent. Think about it, why would there be grit in ANYTHING that lubricates, cools and is used hydraulically? Your diesel instructor was a tard!
Power Service in all my diesel equipment. No issues.
The problem here is that the bio-diesel must be "soybean" based. Most all other bio-diesel sold out there is not and does not contain the properties we want in our fuel. I totally agree with the report though.rustystud

Most pump diesel contains 10-20% bio in Missouri, so the adding anything other than antigel is moot here. Check locally for a place that has a mix near you. I run the 20% mix in my truck, no "corrosion" issues, no algae issues. You have to be careful with the scuttlebutt floating around about fuel additives, its infectious.

As far as a bottled additive, Optilube XPD is the best, but as far as things to put in the tank, its not. A 2% blend of biodiesel(soybean) shown a 30% improvement over Optilube XPD, and 2.8 times less wear than straight diesel. Also, bio comes right out of the pump with the regular diesel here where I live.

Lucas, used motor oil, and other additives makes things worse. Bio can cause corrosion, and if it sits it will at a 100% concentration. The real killers of these trucks isnt ulsd, its neglect and disuse/misuse. Treat it well(bad pun) and it will do the same to you
I wouldn't call him a "tard" just uninformed ! I think what he was trying to convey was that ATF especially in the 1970's had a higher coefficient of friction then regular oil did. I know for a fact that if you used Dexron ATF in a Ford transmission that you would loose your clutches in short order. They where designed to use that higher friction oil. In fact we used to use "Mercon" oil in our GM transmissions to get better performance from them. There was a test you could do to prove this. Take a sample of Dexron oil in you hands and rub them together. Then take some Mercon and do the same thing. You would rub your hands raw in short order with the Mercon oil.
Agreed, not only is biodiesel from other feedstock lower in lubricating value, it is also more corrosive when left idle. Although carbon steel will be fine(generally), yellow metals, cast, and soft metals such as zinc and aluminium experience the brunt of its corrosive properties. Polymers and elastomers like natural rubber, chloroprene/neoprene, andnitrile degrade as well. Note that the following report goes into detail about multiple fuel stocks, but also goes under the premise of using high blend fuel 50% to 100%. It also states the older high sulphur diesel was corrosive due to the sulphur compounds combining with moisture over time and making acids.
Hello thank you for the response. Here in AZ we don’t have winter (maybe 10 days a YEAR below 35) so I assume I’d use this Stanadyne throughout? What’s the ratio? Every fill up or once a month . Whole bottle or what’s your usage?
