nc IA | This is correct.
Magellan pipeline across the state of Iowa a few years back switched from 87 octane base grade (becomes 89 octane with 10%) to 84 octane what the oil industry calls "Sub grade" - it's a lower quality distillate and doesn't burn as well, or have the same energy content as the 87 octane was. By switching to sub grade they make the state minimum spec now only by adding 10% ethanol to get to 87 octane.
The sub grade has a higher profit margin for the oil companies and they get the added bonus of the sheeple believing any resulting issues are due to the ethanol.
On a side note - want to keep your gasoline fresh? Use quality metal cans that don't breath like the NATO style jerry cans. The easy to burn / ignite hydrocarbons are the first thing to bleed out as a can that's not sealed tightly expands and contracts with temperature. Once that happens you're on you way to stale gas and varnish, and thats also how moisture is accumulated.
No different then the age old best practice of filling your tanks at the end of the day with fuel, so that overnight as the air temp cools they don't suck in a bunch of humidity. | |
