Have no operators manual or service manual. What is the manufactures recommended type oil SAE viscosity and quantity to change oil with new filter. I have the filter from the dealer.
the manual i have (actually read it last night) says 10W30 but when i picked up my filter from the dealer they told me 15W40. so i used 15W40 (assuming you have the same diesel engine, not sure what the A54 is)
