My roller skate Hyundai is on a Motorcraft 5W20 OCI right now. Got 2K on it, it's lovely. Level hasn't dropped, clear as water, perfect clear stripe on the dipstick. For a lousy 9 or 10 bucks for this stuff for 5 quarts a year or so back, what's not to like? Best thing is, over 7500 miles, that extra quart may come in handy if it needs a top off. If not, it's mower-oil with a splash of SLOB and a dot of VSOT.
SLOB and VSOT. Anyone even bother with those cat-fouling snake oils anymore? I only use them in the mower and for chain saw bar oil, myself. I consider that the VSOT might be good chain lube for my bicycle, but not my bike.
