Motor Oil Myths Debunked
There's a lot of misinformation about motor oil and when to change it. Here are the most common myths debunked, along with how Cerma Motor Oils provide a better solution.
Myth 1: You Should Change Your Oil Every 3,000 to 5,000 Miles
The Truth: Motor oil doesn't actually "go bad." You change it because it becomes contaminated with carbon and dirt over time. The 3,000-mile rule dates back decades when oil quality was much lower.
The Cerma Solution: Cerma Motor Oils are formulated with Run Clean Technology that breaks down carbon and minimizes contamination. This allows for significantly longer oil change intervals:
- Cerma Motor Oil – Up to 15,000 miles between changes
- Cerma CERMAX – Up to 30,000-50,000 miles between changes
Myth 2: Dark Oil Means Dirty Oil That Needs Changing
The Truth: When engine oil turns dark, it's actually working correctly. The oil is dispersing tiny particles and holding them in suspension to prevent engine sludge formation. Dark oil is doing its job.
The Cerma Solution: Cerma Motor Oils perform normal lubrication and protection while actively moving particles into the filter through our self-cleaning process. Change your filter based on the vehicle manufacturer's recommended interval, not the color of the oil on the dipstick.
Myth 3: The "W" in 10W-30 Stands for "Weight"
The Truth: The "W" actually stands for "Winter." The multi-grade rating system developed by the SAE (Society of Automotive Engineers) includes both hot and cold viscosity ratings:
- The number before the W (10W) = cold temperature viscosity
- The number after (30) = hot temperature viscosity
The Cerma Solution: Cerma Motor Oils are available in various multi-grade options. When used with Cerma Engine Treatments, you may be able to use a lower viscosity oil for increased fuel economy while maintaining full protection.
Myth 4: Oil Additives Will Improve Engine Performance
The Truth: Most motor oils already contain an "additive pack" designed to improve viscosity index, prevent sludge, and protect against rust and corrosion. Adding more additives can sometimes do more harm than good.
The Cerma Difference: Cerma Motor Oils contain proprietary SiC (Silicon Carbide) technology that provides:
- Self-cleaning action that forces contaminants into the filter
- Ceramic protection built into the oil formula
- No need for separate additives
Cerma Engine Treatments work differently than traditional additives. They act as catalysts that form a permanent Silicon Carbide matrix on engine surfaces, providing protection that lasts long after application.
The Facts About Motor Oil
| Common Belief | The Reality |
|---|---|
| Change oil every 3,000 miles | Modern oils can go 7,500-15,000+ miles |
| Dark oil is bad | Dark oil is working correctly |
| "W" means weight | "W" means winter (cold viscosity) |
| Additives improve performance | Quality oil already has what you need |
Why Choose Cerma Motor Oils?
- Extended drain intervals – Save time and money with fewer oil changes
- Self-cleaning formula – Run Clean Technology keeps engine
