Add 2-stroke oil to diesel? Yes or no?

August 16, 2018, 05:43:17 pm

I had a trucker suggest I add 2-strike marine (not motorcycle) oil to the diesel for better lubrication. Is this a good idea or not? He suggested one quart per 100 gallons of diesel. And synthetics is even better. I watched him add a quart to his own truck while we were both filling up.

I've heard the same but for 2 stroke diesels such as the DD 8v92 engines. I think it is because they were designed long before the low sulfur diesel available today and could benefit from the added lubricity.

When I was driving for Watkins-Shepard they prohibited us from adding anything to their trucks (Cummins) except anti-gel in the winter. So I didn't then and don't now. Just sayin.

Nothing to do with being a 2 cycle. Lots of wives tales out there. ULSD/Bio diesel has all the additives needed for lubrication. All diesels may benefit from a cetane booster/biocide/anti gel additive. Diesel may differ from station to station in quality. Remember, you are not buying European quality controlled fuel. I've had some fuel knock loudly but adding a additive got rid of the knock in about one minute. Read reviews before adding anything.

The GrandVention a couple years ago was at Columbus Indiana, home of Cummins. Additives were asked about several times. Same answer every time. Not necessary. At a tech session the Cummins engineering guy said no additive warranted repairs to your engine if it was shown the additive caused a failure. No benefit and the limit of their liability is the couple bucks you paid for the stuff. I use a biocide if the coach sits more than a few weeks. That's it. #1 diesel run through everything as winter comes on up north until we as warm again.

I keep what's left of the gallon of the same stuff next to my tank.

Those seminars and warrantee talk are great for new engines,most of us have 20 to 30 plus year old engines,if somehow somebody
can determine if todays diesel is the same as 30 years ago please tell me.We use diesel kleen,if tomorrow Cummins came out with
an additive they would be saying you can't live without it.I plan on being at the Grandvention next year,if there is a Cummins booth
will make it a point to ask about additives.

The vast majority of the coaches at the GrandVention in Columbus were in the 95-03 range. The questions were about additives for those engines and the answers were directed towards those engines not new engines. Ask again this year. Report their answers. I am sure there is some CYA in these answers. If there were additive reps there they would sing a different tune.

There probably is no correct answer. If you think it helps then go for it. But then there are people out there who will swear they get better milage at 75 than at 65 mph. Physics and aerodynamics notwithstanding. DWMYH.

On our coach I run cenex roadmaster #2 diesel. If I cant find a Cenex where Im at I add power service additive to the fuel. Ive been told add some kind of lubrication to your fuel. These new ones don't care for anything at all. The older diesels will love you if you give them something to snack on. Do it for yourself, try it and check your mileage. You might surprise yourself. This is just my pennys worth!

No magic in my fuel tank, just #2 diesel and the correct amount of biocide. Way back in the early 70s hauling produce with mostly V12 buzzing dozen Detroit's, 1693TA Cats, and KT600 Cummins, nothing but anti jell during the winter.

A few years ago, I searched the internet for "diesel lubricity study" and found an independent report sponsored by "The Diesel Place", and started using Opti-Lube XPD to increase the lubricity of ULSD. This report was also posted on Foreforums.

What is HFRR?
Diesel fuel and other fluids are tested for lubricating ability using a device called a "High Frequency Reciprocating Rig" or HFRR. The HFRR is currently the Internationally accepted, standardized method to evaluate fluids for lubricating ability. The lower HFRR number, the higher the lubricity and the lower the wear. Untreated ULSD has HFRR of 626 while the minimum acceptable standard is between 460 and 520. HFRR higher than 520 results in faster engine wear.

The number 2 lubricity enhancer was Opti-Lube XPD with HFRR of 317 at a cost of $4.25 for 25 gallons.
The number 10 lubricity enhancer was Diesel Kleen with HFRR of 575 at a cost of $1.55 for 25 gallons (does not meet the 520 minimum standard).

When pumping 100 gallons into my tank which has a cost of circa $350, the increased cost of $15 for Opti-Lube does not seem too high when considering the increased lubricity.

By the way, the number 1 lubricity enhancer was BIO-Diesel (B2), and now diesel without BIO is hard to find, so with B5 or B20 is a diesel lubricity enhancer really required? I would like to see a lubricity study which includes B5 and B20 diesel.

Kind of on subject, I remember when they took the lead out of gasoline, the end of the world was coming for older engines! Same for ULSD and older diesels.

The Opti Lube XPD makes both the engine and generator noticeably smoother and quieter.

Those older ones would run good on good old "Sonoco 120".

I use Howes Meaner Power Kleaner. Howes Lubricator

You can find it everywhere and the price is good. I have less smoke, more power, and better mpg. The biggest improvement I noticed was how much smoother the 4 cylinder Kubota runs.

For us two cycle lovers here's a great video on 9 of the best Detroit two-cycles ever built. Turn your speakers up. It's peddle to the metal for the fire truck!

Jerry,

It's too hot to go outside but good to sit in front of the big screen and watch your video. How could an engine be so glass smooth but sound so good? I love finding tunnels and underpasses so I can slide open the window and listen to the Jake. No crude and rude blat like the 4 cycle trucks make, just music.

They should be up for a Grammy!

Mileage? It gets as good or better than any other 30,000 lb, 102" coach. That guy needs to be taught a bad lesson!

Now if I only had the ZF tranny.

Thanks Jerry,

Pierce

Pierce,
Another great video of a fire truck with a tuned up DD6v92 and letting that Jake do it's thing. Loud, proud and waking up the neighbors!

That guy was flying. We could only legally go 35 mph in town. Hope no one stepped off the curb. My neighbors would kill me if ours was that loud.

OK, rename if we have not covered the topic.
