What does API CH 4 mean?

Service. CK-4. Current. API Service Category CK-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel engines.

What does API CK-4 mean?

API CK-4 oils will replace current API CJ-4 engine oils and will be backward compatible with most applications where engine manufacturers currently recommend CJ-4. The new CK-4 oils will provide a number of improvements over CJ-4, including improved shear stability, oxidation resistance, and aeration control.

What is CJ4 engine oil?

API Service Category CJ-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2007 model year on-highway exhaust emission standards as well as for previous model years. CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval.

What is Tier 4 engine oil?

What is CK-4 Oil? It’s the newest generation of diesel engine oil. Although it was developed especially for Tier 4 engines, you can use it in older models too. The industry calls that “backwards-compatible.”

Is cj4 a synthetic oil?

AMSOIL Premium CJ-4 15W-40 Synthetic Diesel Oil is recommended for extended drain intervals in engines that are unmodified and in good operating condition.

Is gf4 oil synthetic?

A unique blend of synthetic and high viscosity index Group II mineral oils combined with a carefully selected additive package, provide maximum protection against wear, rust, corrosion, oxidative thickening, acid formation, sludge and varnish deposits.

What is the difference between CK-4 and CJ-4 oil?

The new oils provide better oxidative stability, more aeration resistance, and enhanced shear stability. Additionally, CK4 oils provide better protection for engines than CJ4 oils. Using CK4 should increase the time between oil changes and improve fuel economy, as well, thanks to lower viscosity grades.

Is CJ4 a synthetic oil?

What weight is CJ4 oil?

SAE 15W-40
This oil has a weight of SAE 15W-40, meaning it has an SAE viscosity rating of 15 in cold temperatures and a rating of 40 at normal operating temperature.

What is the difference between CJ4 and CK4?

What is GF4 motor oil?

AUTOGUARD SYNTHETIC BLEND GF-4 MOTOR OILS are premium- quality, high detergent automotive engine oils specially formulated to meet the stringent lubrication demands of today’s engines.

Can CK-4 oil be used with API service categories?

API CK-4 oils exceed the performance criteria of API CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories. When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations.

What are the API service categories for diesel motor oil?

Diesel motor oil categories (for heavy-duty trucks and vehicles with diesel engines): Oils designed for diesel-engine service fall under API’s “C” (Commercial) categories. See the GASOLINE ENGINES and DIESEL ENGINES charts on the next pages for descriptions of current and obsolete API service categories.

What is the difference between “C” and “CI-4 PLUS” engine oils?

“C” category oils have been formulated primarily for diesel engines and may not provide all of the performance requirements consistent with vehicle manufacturers’ recommendations for gasoline-fueled engines. 5. THE API SERVICE SYMBOL WITH CI-4 PLUS The “CI-4 PLUS” designation identifies oils formulated to provide

Which grade of viscosity grade does not apply to API certification?

(9) For all viscosity grades: If API CH-4, CI-4 and/or CJ-4 categories precede the “S” category and there is no API Certification Mark, the “S” category limits for phosphorus, sulfur, and the TEOST MHT do not apply.
