DIC - Change Engine Oil

[jwhaler17]

The 3,000 mile/oil change is a VERY conservative figure when determining when oil should be changed. It's like the dosage on over-the-counter medicine... They take the lowest amount that showed no adverse effects on the populous at large; the "safest bet" in other words.

aren't you supposed to get more mileage on synthetic oil? can it tell the diff between syn and conventional oil?

If so, I haven't noticed on both accounts.

The car knows nothing about the oil type or quality, only the driving habits and conditions. It cant tell synthetic.

i understand that it can't tell the diff. but aren't we cheating our wallets if we change synthetic oil sooner. isn't synthetic supposed to last longer?
