Yep, there is no way to stop the wives tales. You never even bothered watching the video posted, did you?

Let me explain again as I did in other threads on this topic. I pay about $45 for an oil change, Costco sells synthetic oil pretty cheaply. I change every 3000 on both vehicles, $45 is chump change (btw, watch that video that was posted). New oil is always a benefit over old oil. Oil does not "go bad", it gets contaminated and the additives deplete. New oil s always better than used oil.

Per a local radio show in Houston hosted by 3 different successful auto shop owners. Car manufacturers design their oil change and maintenance intervals to make the original buyer happy. I forget the number, but the average car owner only keeps their vehicle a couple years and trades it in. Those maintenance intervals are designed to make that new car buyer happy so they will buy another one. The less they spend the more an image of reliability sticks in their head and the more apt they will buy another one. Car manufacturers do not worry about the second and third owners (once again, see that video and that mechanic confirms this with that Toyota where the doctor stuck to manufacturers intervals. BTW, he stuck to what Toyota stated and he is paying for a new engine. Think about that a second).

Stop saying to trust the engineers, they are not what drives advertising for auto makers and they do not set maintenance intervals. This is not the 60's where the told you how to adjust your valves in the owners manual.

The argument I keep hearing is that it's "cheap insurance." Again, it's outdated thinking that wasn't even valid 20 years ago.

But they're probably still sold on that fear from oil change places that your engine will blow up if you go to 3,001 miles.

So far, no respondent on here has said they had a modern engine blow up from a 3,000+ mile oil change interval. Go on BITOG and I doubt there are any you'd find there.

But then again, some people here are probably still carrying a 5" 1911 with 230gr .45 ACP and using dial up for internet because that's the way it's always been done? Or maybe carrier pigeons or smoke signals?

If 3000 mile oil change is good, why not 1500 miles?

Modern oil is advertised as "Extended Life". Don't the petroleum companies think shorter intervals would sell more oil? Why not advertise for more frequent changes and make 'mo money?

Wait, wait, wait. I know the answer. The car manufacturers have paid off the petroleum companies.

Don't be fooled into thinking that auto manufacturers are giving oil schedules and even oil weights that are best for your car.
Chevy requires 0W-20 in my 2018 Silverado's V8. The optional V6, which is literally the same engine minus two cylinders requires 5W-30.
The lighter weight oil is used to hit a certain EPA mileage number. Its not better for the engine, it just gets a tiny bit better gas mileage so that V8 will look like less of a gas guzzler.

Changing your oil every 3,000 miles is a practice passed down for generations. The origin likely stems from the noble effort to provide consumers with a simple vehicle-maintenance rule that left plenty of room for error.

Marketed by fast lubes
Fast lube chains, which first entered the market in the 1970s, adopted and amplified the message through sustained marketing campaigns. Owned by major oil manufacturers, fast lube chains had a financial interest in seeing customers frequently and selling more oil, the vast majority of which was conventional.

Endorsed by your dad and mechanic
While this timeline helps provide context, it does little to address the emotional connection to changing oil every 3,000 miles. The reason so many motorists dutifully change oil every 3,000 miles is because their fathers and their mechanics – two of the most influential groups in automotive circles – told them they should. For many people, the 3,000-mile oil change is a tradition that ties them to the person who taught them many important life lessons, like how to keep your car running properly.

Tradition updated with new technology
Many families pass down traditions, and while the spirit of the tradition is upheld, many elements are updated to reflect current technology and lifestyles. Your call to a distant relative during the holidays may now require Skype instead of a rotary phone. Likewise, your annual family vacation may start at the airport instead of in the family station wagon. In the case of the 3,000-mile oil change, we can preserve the noble spirit of taking good care of our vehicles by establishing a habit of changing oil periodically, but not necessarily every 3,000 miles.

Since the advent of the 3,000-mile oil change, advances in lubrication and automotive technology have rendered it outdated, like adding water to automotive batteries, replacing ignition points and adjusting the carburetor. Now, many vehicle manufacturers recommend changing oil every 5,000 miles or longer, with BMW calling for 15,000 miles between oil changes.

Synthetic motor oil technology
Synthetic lubrication technology plays a significant role in moving beyond the 3,000-mile oil change interval. Synthetic motor oil offers better wear protection, improved resistance to temperature extremes and increased cleanliness properties compared to conventional oils. For that reason, it’s safe to use them longer than 3,000 miles.

AMSOIL products provide confidence with additional protection that goes beyond the standard. It’s what your dad or grandfather may have called the “belt and suspenders” approach. For example, AMSOIL Signature Series Synthetic Motor Oil…

Provides 75% more engine protection against horsepower loss and wear than required by a leading industry standard.

Achieved 72% better protection than required by a leading industry standard, providing ultimate protection against extreme heat and the harmful deposits that can plague turbochargers.

Achieved 100% protection against LSPI.

So, while it’s vital to change your oil and take care of your vehicle, it’s also important to advance your methods in lockstep with the latest technology. And modern synthetic oils have made the 3,000-mile oil change as dated as the rotary phone.
