I'm pretty much done trying to hit 4.4 quarts out of a 5 gallon jug, when 4.4 puts me at bottom mark on dipstick. Just going to do full 5 quarts. (Checked oil next day within 5 minutes of half hour drive). '04, 222K on the clock. Bonus question - Most likely thing that is leaving slight drip on floor? VTEC Solenoid gasket?

2004 Element with 225K miles. Engine ran smooth, then overnight, it's sputtering bad. Filled up with gas 3 days prior, and didn't drive too much before issue. Scanner shows 5 misfire codes. I've added ISO Heet and letting that set overnight. Can all 4 plugs and/or ignition coils crap out at same time? Is it really that bad to use Amazon Iridium Plugs vs. NGK or Denso? Thank you.
