Oil= depends on your milage and engine condition, mine burnt a quart every 1,000 miles so I just kept it full with Supertech brand 10-30w, which FYI supertech is Mobil1 oil

Spark plus, Autolite FTW, dont use ANYTHING else, waste of money, good 'ol autolites are the best

I use Motorcraft 10W-30 Synethic.

Also I would use the Autolite 25's that are recommended above.
