Why Oil Change Intervals Matter

Why Oil Change Intervals Matter

Modern vehicles have become increasingly sophisticated, but one thing that remains the same is the importance of clean oil. Oil remains the lifeblood of even the most technologically-advanced engines, so staying on top of your oil change intervals is essential. Fortunately, many vehicles now have an onboard service reminder that will let you know when an oil change is needed; some models even let you know when the oil level is too low. 

Longer Intervals Make Regular Oil Changes More Essential

As advances have been made in both oil and engine technology, recommended oil change intervals have gotten longer. The old rule of changing your oil “every 3,000 miles or every three months” is now outdated. Many manufacturers now recommend oil change intervals of every 5,000 to 7,500 miles; some intervals are as much as every 10,000 miles. 

This is great news for many drivers, but longer intervals also mean that it’s even more important to change your oil according to the schedule listed in your owner’s manual. Back in the days of 3 months/3,000 miles, if you went an extra month or extra 1,000 miles, the oil was still fresh enough that it didn’t have time to build up much sludge. However, if your recommended interval is 6,500 miles, and you go over another thousand, you increase the risk of sludge developing. 

It’s not just about mileage, either. If you don’t drive your car a lot, the oil still needs to be replaced regularly—even if you only drive it fewer miles each year than what your manufacturer suggests for changing oil. You should still make a point to get your oil changed twice a year because oil breaks down and becomes less effective as it ages. Once this happens, you risk excessive wear and tear on your engine and overheating. If too much sludge develops, it can even cause complete engine failure. 

What is the Severe Service Schedule?

In your owner’s manual, you’ll find different recommendations based on the “normal” or “regular” operation of your vehicle and a “severe service schedule.” Sometimes, it will be listed as “Schedule 1” and “Schedule 2”. There’s a lot of confusion around this, so we’re going to break it down.  

The severe service schedule recommends more frequent intervals for maintenance items like oil changes, air filter replacement, and transmission service based on your typical driving conditions. Although it can vary based on the automaker, you would typically follow the severe service schedule if any of the following apply to your typical driving conditions:

  • Most of your trips are under four miles
  • Most of your trips are less than ten miles when outside temperatures are below freezing
  • You drive in a lot of stop-and-go traffic
  • You don’t drive on the freeway very much and mostly stick to low speeds 
  • You drive in an area that has a lot of dust, dirt, slush, mud, or pollution
  • You frequently pull a trailer or haul heavy loads
  • You frequently drive in areas that can get very hot or very cold

Check your owner’s manual for more information on your vehicle, or feel free to discuss which service schedule you should be following with your service advisor. Since many people have some severe service factors mixed into their daily driving, some prefer to follow the severe schedule to play it safe. 

Conventional vs. Synthetic Oil

It’s also worth mentioning that you should always use the recommended oil for your vehicle. This is especially important if you top your oil off at home. If your car came from the factory with synthetic oil, only use synthetic and follow the synthetic oil interval. 

So, what’s the difference between the two types? Synthetics use higher-quality base oils compared to conventional oil, which makes them more stable and less likely to oxidize and acidify. They take longer to break down, so they offer better protection for your engine. Synthetics help your engine run more efficiently and perform better. Another benefit of synthetic oil is that it keeps your engine cleaner and can better resist sludge formation. Many vehicles that run on conventional oil can convert to synthetic; ask your service advisor if your car could benefit from making the switch!

Extend the Life of Your Engine

Service advisors often report that when they talk to someone with 200,000 miles or more on their engine, the drivers always say the secret is changing the oil on time. Although there could be other factors as well, routine oil changes undoubtedly extend the life of your engine.

How About Some Good News for a Change? Auto Insurance Rebates Are Coming

Just how big is the coronavirus? It’s just 125 nanometers. For perspective, a human hair is 80,000 nanometers thick. That dollar bill you are trying to so wisely spend is pretty thin, right? It’s 100,000 nanometers.  

Miniscule but massive, the coronavirus is having an outsized impact on lives and budgets. Though there’s not an overwhelming amount of good economic news just now, there is one small glimmer of relief. Auto insurance companies are giving dollars back to their customers in the form of COVID-19 refunds.  

Insurers base their premiums on the number and cost of claims they get. With fewer miles driven, those claims are going down.

The top ten insurers have announced plans to return more than $7.5 billion. Though that’s a lot of cash, watchdog groups are asserting the insurance industry could be doing more. These companies are saving tens of billions of dollars even after accounting for the money they are giving back.

How Large Are The Refunds?

The refunds range from around 15% to 25% of premiums, though the timeframes and, therefore, the amounts differ. For example, Farmers Insurance Group of Companies is offering its policyholders a miserly decrease based on one month, while Geico is much more generous, refunding six months’ worth, nearly $2.5 billion.

The largest insurer, State Farm, announced it would return 25% of premiums for a period of 10 weeks, from March 20 through the end of May, a $2 billion reduction in premiums. State Farm, a mutual insurance company, is owned by its policyholders and is calling the payment a dividend.

Most insurers are basing relief on payouts for the premiums paid in April and May. The fourth-largest insurer, Allstate, was the first to announce reduced payments to its policyholders for these two months, quickly followed by announcements from Progressive, USAA, and Liberty Mutual.

Further assistance related to the pandemic includes allowing policyholders to defer payments and pausing cancelations due to non-payment of policies.

It may not be sufficient to satisfy consumer protection groups or enough to make much of a difference in your bank account, but the total amount is quite a pile of cash. If you stacked the total payout announced so far—$7.5 billion—in one-dollar-bills, it would climb over 500 miles into the sky or something like 750 trillion nanometers.
