I am considering the purchase of a 1988 BJ74 with the 13B-T engine and had a question regarding the available ULSD fuel in the states. For those who have this engine, have you noticed any increase in fuel pump/injector wear? Do you add any chemicals at fill ups? I work on a ship and we have converted the medium speed four strokes diesel to low sulpher fuel (from heavy fuel) and had to add oil injection lines to help the fuel pumps with lubricity. Thanks in advance! Bob

I run additives, for extra lubricity and winter conditions. Lots of brands out there. This is a snow day reading activity 
. You will have to decide your self on how much and what brand.

Any off the shelf gas station additive will work fine.
I personally like a bit of 2-stroke oil. Or even ATF will work fine.

This is a good thread as I was wondering what the effects of ultra low sulfur diesel does to the JDM diesel engines (shrink seals, etc).
It is unclear when Japan started reducing the PPM of sulfur in diesel sold there but it seems to be around 1992 or 1993 so any engine before that probably requires the preventive measures outlined in this thread?

it provides seal lubrication. but it does not provide any cold weather protection, that is where you will want to use something else ;
Opti-Lube XPD, FPPF, Schaeffer, are just some examples. these all have different results per testing that you can find online.
have you introduced us to your new vehicle yet? I can't seem to recall. Are you keeping both?
Yeah I am keeping both (at least for now).
I haven't formally made an introduction but I will post up some pics in the 70's US registration thread later.
I don't think the lack of sulphur was the big deal everyone thought it was and its not actually the sulphur that does the "lubricating".
It was more a case that when they took the sulphur out to comply with emissions laws, other compounds that did lubricate came out with it.
In more recent years fuel refiners have worked out how to add back lubricity. Shell Australia are adding 5% bio fuel to their diesels
Countries that do have a high proportion of diesels do not have diesel pumps dying left right and centre.
Inline pumps are much less prone to wear than rotary and would be the least affected.

Hello,
Diesel engines are sturdier than we think.
Fiddling too much with the fuel adjusting screw, for instance, especially when you do not know what you are doing, kills more engines than sulfur. Engine abuse is deadlier than sulfur as well.
I agree, companies work on fuel formulations with better lubricity.
In the end it is the same case as that of viscosity modifiers with engine oil. A few fluid ounces of an off-the-shelf additive will do.
