When it comes to maintaining your vehicle, one of the most crucial aspects is ensuring you’re using the right type of oil. The type of oil your car takes is often specified by the vehicle’s manufacturer, and it’s usually indicated by the vehicle’s registration number, or “reg” for short. Using the wrong type of oil can lead to a range of problems, from decreased fuel efficiency to engine damage. In this comprehensive guide, we’ll delve into the world of car oil, exploring the different types, their characteristics, and how to determine what oil your car takes by reg.

Understanding Car Oil
Car oil, also known as motor oil, is a lubricant designed to reduce friction between moving parts in your engine. It’s essential for maintaining the health and longevity of your vehicle. There are several types of car oil, each with its unique characteristics and uses.
Viscosity
One of the primary characteristics of car oil is its viscosity, which refers to its thickness and flowability. Viscosity is measured in centistokes (cSt) or Saybolt Universal Seconds (SUS). The most common viscosities for car oil are:
| Viscosity | Description |
|---|---|
| 0W-20 | Thin, flows easily in cold temperatures |
| 5W-20 | Medium, suitable for most driving conditions |
| 10W-30 | Thick, suitable for heavy-duty driving or extreme temperatures |
Oil Types
There are several types of car oil, each designed for specific engines and driving conditions. The most common types are:
- Conventional oil: Suitable for most passenger vehicles, conventional oil is a blend of petroleum-based hydrocarbons.
- Synthetic oil: Made from chemical compounds, synthetic oil provides superior lubrication and protection in extreme temperatures.
- Synthetic blend oil: A mix of conventional and synthetic oil, offering improved performance and protection.
- Full synthetic oil: A 100% synthetic oil, providing superior lubrication and protection in extreme temperatures.
- High mileage oil: Designed for vehicles with high mileage, high mileage oil contains conditioners to seal leaks and prevent wear.
Determining What Oil Your Car Takes by Reg
So, how do you determine what oil your car takes by reg? The process is relatively straightforward:
Check Your Owner’s Manual
The first place to check is your owner’s manual. It should specify the recommended oil type and viscosity for your vehicle. (See Also: How to Read Engine Oil Weight? A Simple Guide)
Look for the Oil Capacity Label
On the driver’s side doorjamb or inside the fuel filler door, you’ll find a label indicating the oil capacity and type.
Check the Oil Filler Cap
The oil filler cap on your engine should have a label or a symbol indicating the recommended oil type and viscosity.
Consult a Mechanic or Oil Change Professional
If you’re still unsure, consult a mechanic or oil change professional. They can check your vehicle’s specifications and recommend the correct oil type and viscosity.
Why Using the Wrong Oil Can Be a Problem
Using the wrong oil can lead to a range of problems, including:
Decreased Fuel Efficiency
Using the wrong oil can decrease your fuel efficiency, leading to increased fuel costs and emissions.
Engine Damage
Using the wrong oil can cause engine damage, including wear and tear on moving parts, corrosion, and even engine failure. (See Also: Should I Get Synthetic Oil Or Blend? The Ultimate Guide)
Increased Emissions
Using the wrong oil can lead to increased emissions, contributing to air pollution and environmental degradation.
