anybody running an additive in the low-sulfur fuel? I had a customer who runs the same 7.3 furd that i do that has 500 g's on it and he swears by running a smidge of 2-stroke oil in each tankful... I'm not opposed to purchasing a commercial product either, if it will help longevity/lubrication....


thoughts?
 
He must have been an old 2 stroke engine operator. We used to add it it to our tow trucks way back in the day.

I know 7.3 guys with 500k on them who do not add anything. Oil changes are the key.
 
I run power service in my Deuce multifuel and the 4500 LMM duramax. Works fine I guess, wont really know until one blows up or doesn't blow up. It does work great as an antigell, no problem at -25 in the mountains.
 
I've got an 01 LB7 with 407k miles on it.

When my injectors were getting weak, I used seafoam. Seemed like the smoking was much less, and ran better when I would. If I didn't use it for a few tanks, seemed to get smokey again. I've since replaced the injectors.

I've run some powerservice in the winter.

I've considered the 2 stroke oil, but have not run it.
 
I’ve run two stroke, Lucas, power service, marvel, hotshot, seafoam, etc in my diesels. Lucas was the only one that seemed to do anything and I would get a consistent 1.5mpg increase with it. Additives add up though and in the end I quit worrying about it and quit using them.

I would agree with that and Wade about just changing oil. But clean fuel foursure! And Lube for the injectors and pump. I could care less about fuel mileage. I do care about replacing injectors and pumps. Our current 12 Duramax has a cp4 that is known to be a crapshoot for longevity. 12 grand if it shit it’s self and sends fillings throughout the fuel system. So yeah a bit of lube is in the back of my mind.
Still not sure what is the best and what is snake oil. I can only go by what guys are saying.... and everyone has a different situation so there is that!?
 
I used to run a mix of power service and marvel mystery oil. 3 quarts ps, 1 quart marvel. That gallon would last 6-8 tanks of fuel on my dodge. Depending on how much I poured in. Worked pretty good. Only stopped because I got lazy :doah:

Now I use just power service every few tanks. Quart bottle, whole thing.
 
I use some Power Service stuff in the winter to avoid gelling,and have added numerous other diesel fuel additive products I came across for sale cheap at the flea market..

--one that made a noticeable difference was some old stock "Gunk"/Solder Seal brand "fuel oil conditioner" a guy who ran a heating and A/C business had--bought 4 cans for a buck each,and wished later I had bought the two cases of 12 he had...the old 6.2 idled smoother and had more pep than it ever did with that mixed in..seemed to start easier too--the can had instructions on how to use it in diesel fuel ,I just put a whole 12 oz can in to a full tank..


I came across another seller who had six cans of Standyne diesel fuel treatment,I bought all of them for $1 each..have not yet tried any though,I did not even burn 2 full tanks of diesel all of 2020 and didn't remember to add any before winter set in..
I hear that stuff is among the best fuel treatments..

Never tried Lucas yet,or any of the other "Hot Shot" brands,I did try adding a quart of 2 cycle TC-3 oil to a full tank one summer ,it did make a noticeable difference,the clattering was reduced a lot,but as cold weather approached,it made it start harder..made the exhaust smell better too though..

I also tried a quart of SAE 30 motor oil one fall,it too seemed to quiet down the engine quite a bit,and a bit more peppy,but when the temps dropped that November it started giving me grief about starting up cold..after I ran that tank out and put fresh winter blend diesel in it with some Power Service it was easier to get lit from a cold start..

Back in the day they had "Siloo" brand diesel fuel treatments and cleaners,fuel de-icer stuff,that brand seemed to work very well,many truckers swore by it and wouldn't use any other brand..
I think they went out of business ,haven't seen any around except at swap meets and flea markets ,old stock left over guys had hanging around..my older brother used it in his 6.5 Turbo '93 K2500 and said it "woke it right up"..

I'm not sure any of these fuel treatments are really needed,or are doing my 6.2 any good,it likely has a ton of miles on the injector pump and its already "too late" to protect it,adding motor oil may help mask a pump thats got some wear issues though in hot weather--I just keep the fuel filters changed and buy only winter blend fuel after November ,they add some anti-gel to it at the storage tanks..
 
I try to add a qt of 2 stroke occasionally in my Dodge, I've been doing it sporadically for many years now. I've never noticed any difference but figure it's got to be better than nothing. I wish it would make a difference in mileage but I've just gotten used to sucky mpg's.

How many gal tank is that?
 
I run Archoil AR9100 friction modifier in the oil and AR6500 fuel treatment. Might be snake oil or maybe not? Truck runs smoother with it. I have no idea if it helps improve mileage...the sound of a straight pipe and manual trans keeps me smiling.
‘99 7.3 stock injectors with 340k
 
@ryoken it's a 34 gal tank.

@urbex I'll agree there is higher cost and maintenance involved and diesels don't necessarily get better mpg's. My Dodge only gets about 7.5 mpg's pulling my Blazer (guessing 9k lbs w/ trailer) which is probably close to what a 454 would get BUT I can do it all day cruising at about 2k rpm's (70 mph) without a bunch of up/down shifting.

This thread shows very well why I went back to gas motors in light duty trucks...sure, diesels "get better MPGs" than gassers, but am I REALLY saving anything after accounting for the additional acquisition cost, higher fuel costs, much higher maintenance costs, costs of all these additives I'm supposed to be running, and then still have stupid expensive repair costs anyways.

When I ran the numbers for myself, I found that the diesels were costing me much more overall, and I was better off just feeding a big block gasoline in large amounts..so I quit running anything but straight fuel in my 7.3 until it blew up, and I have yet to be able to convince myself it's worth fixing.

wasn't looking for a gas vs diesel debate... just trying to treat my "new to me" junk as good as I can..
 
This is a pretty good video of comparing different additives albeit winter blends but he still covers lubricity. I used to run Howe’s addictive in our loader and all the diesel tanks on the rigs in the winter months... then saw this video and ended up switching to the Stanadyne. Howe’s was actually worse than just diesel.
