Acid is a byproduct of combustion. Oil contains bases, to neutralize the acids. This is one of the things that an oil analysis test can check (Total Base Number -- costs extra, but it tells you if your oil has miles left in it, from the acid aspect, which is important for extended oil drains, if that is your goal): this is why they say XXX miles or 3-4 months, between changes. Truth is, oil gets changed way too often, before it is worn out, which squanders our precious resources. ;-)
To answer your question, it doesn't matter, in all honesty, unless your oil has 7,000+ miles on it, in which case, it likely needs changing.
For the
SeaFoam, be sure to monitor your oil's color after adding it: once it darkens, regardless of milieage, change it! Make sure to shift through all five gears, before you dump the treated oil, to flush the transmission, as well as the rest of the engine. If your oil changes to black, after just minutes of running with the
SeaFoam, it is time to change it. Cheers!
