The company got insured, so this will be easy. Just provide as much data as the company needs (this will make the process faster a bit) and your lost will be minimized if proven innocent (but inconvenience cannot avoid la).
BTW, from 5w40 to 15w40, most engine oil with these viscosity/grade will fit most cars without problem. But some only support either petrol or diesel engine and some support both petrol and diesel engines (but under normal circumstances, the engine won't fail in short time of period as the lubrication is there). You will need to use the same oil for same engine for long mileage before some abnormal wear will appear. If 0w20 for 600whp modified car then different story. The engine may fail in short time (but still should be more than 3 hours cuz the coolant is taking off the heat and engine oil won't be overheated and lost the shear strength, lubrication integrity and etc).
Hope Mr. Chaser can get this solved and let us know what happened. I'm willing to be a genie pig for testing the oil with my 13B if got free oil supplied :D
