What's thicker, oil 5W30 or 10W30?

10W-30 oil is thicker than 5W-30 when cold, but both oils have the same thickness (30-weight) at normal hot operating temperatures; the '5W' means it flows better in cold weather, providing faster lubrication during startups, while the '10W' is thicker when cold, making 5W-30 generally better for cold climates and modern engines. 

What is API Cg-4 oil?

API CG-4 oils are required for engines meeting 1994 emission standards. These oils provide effective control of high-temperature piston deposits, wear, corrosion, foaming, oxidation stability and soot accumulation. API discontinued licensing diesel engine oils against Service Category CG-4 on August 31, 2009.

What oil is best for older engines?

For older engines (75k+ miles), the best oil is a high-mileage synthetic or synthetic blend from top brands like Mobil 1, Castrol GTX, or Valvoline MaxLife, as they contain seal conditioners to prevent leaks, anti-wear agents, and detergents to clean sludge, often using the manufacturer's recommended viscosity (e.g., 5W-30, 10W-40). Always check your owner's manual first for specific viscosity and type recommendations.
 

What are the 4 types of API?

The four main types of APIs, categorized by audience and access, are Public (Open), Partner, Internal (Private), and Composite APIs, each serving different needs, from general developer access (Public) to secure B2B integration (Partner) and internal system efficiency (Internal/Private), with Composite APIs combining multiple calls for better performance.
 

What is the latest API oil?

API SQ, API's latest engine oil performance standard includes ultra-low-viscosity grades, such as SAE 0W-8 and SAE 0W-12, and will launch simultaneously with ILSAC GF-7. All three gasoline engine oil standards will be licensed under API's Engine Oil Licensing and Certification System beginning March 31, 2025.

What is the difference between SAE and API oil?

SAE's job is to define the oil's viscosity, while API focuses on performance and protection. For example, when you see 5W-30 API SP, the 5W-30 part is the SAE rating (which refers to how the oil flows at different temperatures), and API SP is the American Petroleum Institute's classification for gasoline engine oil.

What are the three types of engine oil?

The three main types of engine oil are Conventional (Mineral), Synthetic Blend, and Full Synthetic, each offering different levels of performance, protection, and cost, with conventional being basic, synthetic blends offering a mix, and full synthetics providing the highest quality lubrication for demanding conditions. A fourth popular category, High-Mileage Oil, is also available, which is often a synthetic blend or synthetic with added conditioners for older engines.
 

What happens if you use semi-synthetic instead of fully?

Semi-synthetic oil shouldn't damage your car's engine, but as previously mentioned, it may not deliver the best performance. Is fully synthetic oil better? Yes, fully synthetic oil if better than semi-synthetic oil.
