that is what I was worried about with the mobil 1. I've run the 5w30 supersyn in my car for the last 145,000 km with no problems whatsoever but the cf rating was bugging me especially since the real diesel specific oils are up to cj. I was thinking it was worth it to get a specific product engineered to do the job rather than get a product that is marketed to cover too many applications
anyone know of a truck stop or diesel mechanic in the north east around st-albans or burlington vermont that sells oil and antifreeze products that are diesel specific. I'm getting ready to flush the coolant and am running into the same problem. all the parts stores have is generic automotive type antifreeze and not diesel engine specific
thanks

For the antifreeze, all B series I have seen call for just regular EG; ethylene glycol, or LLC; long life coolant, but either should be an EG base only, and never exceed 50% antifreeze. My
B3030 manual states 50/50 antifreeze/water or 40/60 meet specifications; and freeze points are -37F/-12F at 50%, and -24C/-12F at 40%. I guess if you live where; or want freeze protection below that, one would have to mix at probably 60/40, and dilute it once warm weather arrives, since concentrations above ~60% don't transfer heat well. To bring regular EG antifreeze up to what a lot of diesel manufacturers call for with sleeved engines, and/or several dissimilar metals used throughout the engine is just a DCA inhibitor along with test strips. NAPAcool or similar is not hard to find, but if you hit some truckstops or parts stores that cater to truckers/heavy equipment you should be able to find some pre-charged with the additive already in it; usually it is purple in color. I think I will use a G-05 spec coolant in my
B3030 when I service it in the future, it is an EG base with a good additive pkg as is, and many US and Euro diesels spec it. Chrysler specs it to be red in color, Ford, Cat, MB, MTU and others spec it in a very lightly tinted yellow/gold. A good read site is: Ashland Oil, then Valvoline/Zerex for specs. Kubota, per my supplied manual, supplies a EG based LLC, but even though it is a long life, it states it is good for 2 years service only.
On the oil, CF-4, and the CG and CH oils are now easier to find and are supposed? to be fine with low sulfur, and ultra low sulfur diesel. Do you know what fuel is available in your area?, even though high sulfur fuel may be available in your area, if it is like the US, most fuel distributors just use the same fuel for the off road pumps, just add the dye when truck is filled, or is added when it is dumped at the retailer, so most, but not all off road is the exact same as the on road pumps with the exception of the added dye marker. The reason I am stating that is IF you might be declining the viscosity you want due to the CG/CF ratings thinking you are using high sulfur fuel, since CG/CF oils require shorter change intervails with LSD, and ULSD. If you just want a high TBN number, regardless of what fuel is available in your area, a post in the last few weeks shows that John Deere markets a good synthetic, with a good additive pkg; with a high level of zinc at a decent price that IIRC is supplied in weights other than 15W40, and is supplied by ESSO Canada.
