Oil Change Services in Frankfort, Kentucky

If you’re like most people, you’ve heard time and again that regularly changing the engine oil is THE key to extending the life of your engine. That’s true! Oil changes are a relatively low-cost way to care for your vehicle to ensure it keeps running a long time. The oil in your engine not only lubricates all the moving parts, keeping them from unduly wearing on each other—which can cause ridges, dips, and scratches that affect your vehicle over the long term—but also helps cool the engine, prevents sludge buildup, and removes contaminants that can lead to overheating or reduced performance. Over time, old oil breaks down, becomes contaminated with dirt and debris, and loses its ability to protect critical components, potentially leading to decreased fuel efficiency, increased emissions, and even catastrophic engine failure if neglected.

Engines are very complex creatures, and it’s far better to spend a little every 3 months or so (or follow your manufacturer's recommended interval, often 5,000–10,000 miles depending on oil type and driving conditions) for an oil change than it is to spend a lot down the road to rebuild or replace your engine. The fact is, we’re talking about spending less than $100 per oil change versus several thousand dollars—typically $2,500 to $10,000 or more—to repair, rebuild, or replace the internal mechanisms of the engine due to preventable damage from poor lubrication.

Understanding the Differences Between Motor Oil Types

There are three main types of motor oil used in vehicles today: conventional (mineral), synthetic blend (semi-synthetic), and full synthetic. The key differences lie in how they're produced, their molecular structure, performance under stress, longevity, and cost. Always check your vehicle's owner's manual for the recommended type, as many modern engines (especially turbocharged or high-performance ones) require synthetic oils to maintain warranty and optimal performance.

1. Conventional Oil

• What it is: Refined directly from crude petroleum. It contains natural mineral base oils with varying molecular sizes and some impurities.
• Pros:
  • Cheapest option.
  • Sufficient for older, low-mileage vehicles with simple engines and normal driving conditions.
• Cons:
  • Breaks down faster at high temperatures, leading to sludge buildup and reduced engine protection.
  • Thicker in cold weather, slower to flow and protect during startup.
  • Shorter lifespan: Typically requires changes every 3,000–5,000 miles.
• Best for: Older vehicles, light-duty driving, or budget-conscious owners where the manufacturer allows it.

2. Synthetic Blend Oil

• What it is: A mixture of conventional mineral oil and synthetic base oils (usually 10–30% synthetic, though ratios vary by brand).
  
  
• Pros:
  • Better than conventional: Improved resistance to oxidation, better flow in cold temperatures, and some reduction in sludge.
  • More affordable than full synthetic while offering a step up in protection.
  • Good middle-ground performance.
• Cons:
  • Not as durable or protective as full synthetic.
  • Lifespan similar to conventional in many cases (around 5,000–7,500 miles).
• Best for: Vehicles that experience moderate stress (e.g., occasional towing, highway driving), or as a cost-effective upgrade from conventional.

3. Full Synthetic Oil

• What it is: Chemically engineered in a lab from synthetic base stocks (no crude oil base). Molecules are uniform, with fewer impurities and tailored additives.
• Pros:
  • Superior protection: Resists breakdown in extreme heat/cold, reduces wear, prevents sludge, and cleans existing deposits.
  • Longer intervals: Often 7,500–15,000+ miles (depending on vehicle and driving).
  • Better fuel efficiency, engine cleanliness, and performance in turbocharged/high-performance engines.
  • Excellent flow in cold starts and stability under heavy loads.
• Cons:
  • Most expensive (typically 2–3x the cost of conventional).
• Best for: Modern vehicles, turbocharged engines, extreme climates, towing/heavy loads, high-mileage cars, or if you want maximum engine longevity.
