The coach I bought has had the oil change at FOT since new. It is below the full line and I was getting ready to take a long trip and wanted to carry a gallon with me in case if needed. I have emailed the service tech I had visited with before and left message for James but have gotten no response back.
Engine is the ISX15-600
2114 ih45? Probably some super conductor? ^.^d :))
Just look up what Cummins suggests for your engine..
2114 ih45 is in your signature.. just playing.. Safe travels ^.^d
Not that it matters but I think Cummins endorses Valvoline.
You should be able to just call parts at FT.
Yup, that is an excellent place to start. VERY likely that parts orders the oil from the supplier.
For this engine Cummins recommends Valvoline Premium Blue or Premium blue extreme 10W-30 C-4, CJ-4
I will give parts a call. Wish I would have thought of that!!!!
