Super Low Sulphur Diesel and Cat engines???
With all the speculation about the ULSF and the fact that we are
going to have to run it, I spoke to a CAT engineer at the FMCA rally. Most of the guys from CAT were sales guys but I went back 4 times looking for the engineer to discuss this very issue. Basically, this is what he had to say. Lubricity is very much a concern but there will be additives that will be blended into the fuel and additives that can be added to the fuel. His take was the most important issue was the crankcase oil. A new oil will hit the market that should be used. If that oil is used along with some lubricity then things should be ok. A guy that has an injector rebuild shop said he uses ATF, upon filter changes he fills the fuel filter with ATF and it will not hurt a thing. Actually good for the seals and lubricity of the injector pump) This is where it gets interesting. The CAT guy said that in todays fuel there is a higher level of sulpher produced as a by product in the engine. Some of the sulfer is exhausted through the exhaust and some is washed into the crank case oil. Todays oil had some additive to neutralize the sulpher (because if you add moisture you get sulphuric acid..not too good in the engine) The NEW OIL, will not have as much additive to remove the sulpher because there will not be as much sulpher. He said the oil is probably the biggest issue to be concerned with. Naturally this begs the question of "If I am using Rotella today and it neutralizes the sulfer then why can't I continue to use what I am happy with...he said you can (uh wait you just explained...oh never mind.. engineers sheeesh) But todays oils will eventually be phased out. He also said that CAT has logged the most trial miles (over 7 million on test vehicles) and they are probably the most prepared. Detroit was next but way behind. My personal take on it is that I am going to continue to use Rotella. Use ATF in the fuel. As I do now. I have a tendency to believe the "guys with dirt under thier finger nails" for 20+ years...they see it from where the rubber meets the road and NOT what specs, tech documents etc say. There are ALOT of 3208's in heavy equip, boats, RV's and such to simply turn their back on those "existing customers" I would not want a 2 stroke though that can be confusing. Great topic for debate though. Scott B 86FC35 SC --- In WanderlodgeForum@yahoogroups.com, "birdshill123" > > It is amazing how a thread can change.
