6 Ways to Extend Oil Change Intervals

1. Check the owner’s manual – Many vehicle owners will automatically have their oil changed every 3,000 miles. This interval has been around for most of the driving population’s lifetime, but due to advances in the oil and automobile industries, this practice may be outdated for your vehicle. It’s not uncommon for owner’s manuals to read between 5-15k miles, so look and find out how many unnecessary oil changes you might be paying for.

2. Bypass Filter – Using an oil filter that meets the engine manufacturer’s specifications is a great practice. Installing a secondary filter such as the Frantz Filter is an even better practice. The Frantz Filter removes smaller particles that can’t be caught by the OEM filter (down to 2 microns), oil temperature is lowered, and moisture is removed from the oil. Blackstone Laboratories conducted a third-party test where they discovered brand new oil was dirtier than used engine oil (4,929 miles when drained for test). With a Frantz Filter, most oil can go 50,000 miles before needing drained. We recommend oil analyses every 25,000 miles to ensure the oil’s TBN (see below) is still at optimal levels.

3. Oil Analysis – Bubba from Bubba’s Quik Lube can’t look at engine oil on a dipstick and know it needs changed; even if he says he can. Sending your oil out for an analysis is the best way to learn the condition of your engine oil, detect issues before they become headaches, and determine a safe oil change interval.

4. FR3 Friction Reducer – FR3 will extend the host oil’s performance in shear stability, oxidation stability, film strength and wear reduction. An innovative synthetic PAO/ester base offers complete compatibility with all diesel and gasoline engine oils, as well as all conventional, semi synthetic and full synthetic engine oils. FR3 can be used in any viscosity engine oil, and with any OEM full-flow or aftermarket bypass filtration system.

5. Boost your TBN – TBN stands for Total Base Number. It is a measure of how much active detergent and dispersive additive is left in your engine’s oil. While the base oil in engine oil doesn’t wear out, overtime the TBN in your oil is depleted. When TBN less than 5, your oil has lost its effective capacity to neutralize acid and breakdown dirt. When paired with quality filtration, Hot Shot’s Secret TBN Booster can extend your drain intervals by tens of thousand miles.

6. Maintenance – Spending a few dollars per quart to make the switch to a synthetic engine oil. Heat is one of the biggest causes of oil needing changed. A bypass filter or oil cooler can help lower oil temperatures, but even your cooling system can affect oil temperature. Any amount of scale, debris, or rust in the cooling system can raise the oil temperature; staying on top of cooling system maintenance can save you money on oil changes. Continually check your engine oil level, low oil level accelerates degradation, topping off the system with oil can also slightly replenish the TBN that may have been depleted.

  • I have a 03 f250 with the famous 6.0, I have already changed the injectors twice, once to frozen fuel and the other because it was time. Do you recommend extended oil changes for the 6.0? I have been changing the oil at every 3000 miles because I am not wanting to replace the injectors again. I use a AmsOil bypass filter, egr delete, Sinister coolant filter, EDT, FR3, Stiction Eliminator, and Winter anti gel by Hot Shots. All these additives are very costly. Early oil changes is what everyone has been preached with the 6.0. Any insight would be great.

    • Wow Mike, you’re already doing more than most to extend the life of your truck & injectors! Since you have a bypass filter, as long as you’re doing oil analysis every 5,000 miles and recommended filter changes, there is no need to change the oil that soon.

      In fact, our Armor Oil PAO CK4 5w40 has been proven to last over 100,000 miles with a bypass filter, oil analysis, and some detergent replenishment as needed with our TBN Booster (back to analyzing).
