Use only oils on the lists 229.3 and 229.5 All are synthetics. I use Mobile 1 5W50 due to the heat in GA and most here think I am nuts. But it is on the list. 0W40 Mobile 1 is cheap at Walmart, why not use it?
The manual says 8.5 quarts, but I stick with 8 so my "HI" alarm light will stay off.
91 Octane or higher only.
Trying to save money like you are is understandable - but wreck less. THere is a REASON the factory tells us what they do - many reasons, in fact. Search the tech sections for the oil lists, but I'm here to tell you, 0W40 at walmart will be your best buy. I also recommend FLEECE type filters, not paper. If you start this engine cold at 50 degrees and rev to 2000 rpm, your oil pressure exceeds 100 PSI. Don't put paper in there.
