Solution:
Thanks for your email regarding oils, oil stabalizers and Lucas Oil - with whom we are not familiar. We recommend commercially available API classification oils, usually 15W-40 for our diesel engines, the classification depending on the year, but oils are most always backwards compabible, so the current CH-4 classification would apply. In off-road high sulfur applications, natural gas application and silver bearing applications (not our products) other oils are used. We require no oil stabalizers and caution against using ANY oil additive, period. Refer to the Operation & Maintenance (O&M) Manual for your specific engine, market application and any other relevant factors ... . for the proper maintenance and operation of your Cummins Engine.
