What's your sulfur substitute?

A quart of house brand chainsaw oil per about 20 gallons of fuel keeps my injector pump happy and the pump lets me know when the fuel gets too dry. Starts bogging and surging.
Anybody running marine two stroke in their Stanadyne?

Looking to buy cheap lubricity in bulk. Still haven't figured out a preferred solution. I had been getting quarts for about $10 at the nicest gas station in town, but they aren't reliably stocked, and subbing four stroke oil in a pinch does not help at all.

Would try biodiesel if it was commercially available in my area, but near as I can tell, it is not. Probably for the best, since I don't have the first clue where to find biocide and I'd probably end up brewing diesel kombucha.

Anybody got a solution to this issue for less than ten bucks per tank of fuel? Especially if it can be bought in buckets or drums?

Through Fastenal I found a 55 gallon drum of bar and chain oil for less than $500, comes out to just over $2 a quart. There were a lot more but I trust Fastenals' website more than the other guys.

They also have a 5 gallon bucket for $80

Compared to stuff that's advertised for the purpose, that is a screaming deal. $250 cheaper than the drum I was looking at through Tractor Supply too. Thank you.

Same here, ´dont know about sulphur but liter 2-stroke oil into full tank makes engine running more smoothly.
BTW - Mercedes recommended same rate to their disels at least 10 years ago.

Here in Portland, OR we have R99 (99% renewable diesel). My full stock M1028 with 80,000 miles runs well with it. Prior to the change pump diesel here was B5 or B20. My truck ran fine on that also. There is a station in town that sold B99. It now sells R99. When it had B99 I would fill up occasionally with it. My truck ran a lot quieter with B99 and I think the throttle response was a little better. It also smelled like french fries.
I only use a fuel additive in the winter for easier starts. The one I use is Power Service Diesel Kleen with Cetane Boost.

I've had this truck since 2007 and put just over 50,000 miles on it. It is my Daily Driver, and gets mostly light use (no towing). All I've done to it is routine maintenance and replaced rubber seals and hoses.

We haven't got biodiesel here. I would suggest to city counsel that we have one biodiesel station per 500 head shops, but the city couldn't sustain that many biodiesel stations.

Nothing. I have 52 engines accumulating 2500 hours a year each and we are not experiencing any failures with regards to fuel lubricity. We run R99 which is a hydrotreated vegetable oil fuel. I had low hour 2 injection pump failures under warranty on MTU 4000 engines, 2 injection pump failures on Cat C9.3 engines at ~18,000 hours, 2 injector electrical failures on the C9.3s, and have had two injector failures on John Deere engines, no solenoid alarms but no fuel injected either.

We had performance issues on our larger engines so I did the calorimetry on the R99 and it was within 1% of the test diesel used by the engine manufacturer to certify the engine.

There may be complications with water separation/bacteria with the R99. I'm seeing dirtier filters now with the R99 but that isn't true for all of my vessels so I can't correlate the problem with the fuel.

P.S. on the MTU and C9.3 pump failures only a pump replacement was required, no injectors. The nightmare stories all circle around Bosch pumps which none of the engines in my fleet have.

 

[CARC686]

I don't mind short filter life. Seems this truck has to be overhauled every six months anyway. If it had to be reliable, I'd drive a Toyota. If you'd like to ship me a few dozen drums of R99, I'd stack them up out back. Probably the only way the CUCV will ever get any. I'm never going to clog my fuel system with a SCOBY using the local ultra low sulfur highway diesel. At this point, I'm just glad I don't have to know or care what DEF is.

Not a thing, I have several million miles behind me in various trucks and the only time I've added anything to the fuel was 2 times I needed a biocide and once I had an ice slushy build up around a fuel filter and it started to freeze up, a dash of 911 (red bottle) and back on the road.
I believe most truck IP's will suffer from old dried up throttle shaft seals long before the pump wears out due to lack of lubricity. Adding an oil to oil never made sense to me.

millions of miles with a modern truck, or one designed when diesel had more lubricity?

 

[CARC686]

You used to be able to wash the sludge out of a gasser by putting diesel in the crankcase. I wouldn't dare these days.

 

[87cr250r]

EMD, large railroad engine with design dating back to 1938, specifically warns against flushing engines. The sludge deposits in places where it does not harm and flushing can dislodge the sludge so it can do harm.

 

[CARC686]

I'll keep that in mind the next time I buy a 1938 railroad engine.

 

[87cr250r]

It's still in production today.... The same project manager that developed the EMD engines went on to develop the 71 series Detroit Diesel. Everything they did is present in the most modern engines. Otherwise, modern oils mean fewer deposits but if you've got them it's best to keep them where they are.

I thought we were agreeing with eachother?

I've been grumpy lately. I hope you'll accept my apology. Have a good week.

Take few good drinks as today is Midsummers Day. I hope in your side too?
