Isc350 oil capacity
Trying to reconcile differing data for 2000 U270:
1. FT owners manual, Appendix A Lubrication and Capacity reports ISC8.3 20 qts with filter
2. Cummins Operation and Maintenance Manual (provided by FT withcoach when new) reports standard engine total system capacity at 21 qts (22 w/deep sump oil pan) and Oil Pam low to high for standard oil pan 16-20 qts and deep oil sump (17-21 qts). Not sure which sump was provided to FT
3. Beamalarm reports 20 qts
4. Cummins data sheet for ISC350 reports 6.3 gallons (25.2 qts)
So I assume go with FT and beam alarm?
Thanks for your thoughts.
