What is CK4?

What is CK4?

CK4 oils are being referred to inside the industry as “High HTHS” engine oils, and FA-4 oils are being referred to as “Low HTHS” oils. These Low HTHS FA-4 oils are being designed to provide fuel economy above and beyond current CJ-4 and FA-4 oils through the use of thinner viscosity fluids.

Is CK4 oil backwards compatible?

CK-4 is designed for both over-the-road and heavy equipment and is also backward compatible.”

What is the difference between API SN and API sp?

GF-6B oils replace 0W-16 oils. API SP replaces all API SN. This includes a timing chain wear test and fuel economy improvement test when using very low viscosity oils, among other tests.

What is the FA-4 oil specification?

API FA-4 engine oils are designed with a lower high-temperature high shear (HTHS) viscosity than their API CK-4 counterparts. This means that when at operating temperatures, these oils flow more quickly through the engine, providing vital lubrication to the internal hardware.

What is CK4 diesel oil?

Lucas CK-4 is a premium Heavy Duty Motor Oil blended with high quality API Group II and Group Ill base oils and a cutting-edge additive package providing the robust performance required by modern diesel engines while assuring good fuel economy.

What is the difference between CJ4 and CK4?

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.

What’s the difference between CJ4 and CK4 oil?

What is CJ 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. Oil Interchangeability Guidelines and the API Guidelines for SAE Viscosity-Grade Engine Testing.

Is SP better than SN oil?

Oils may have more than one performance level. For automotive gasoline engines, the latest engine oil service category includes the performance properties of each earlier category. If an automotive owner’s manual calls for an API SN oil, an API SP oil will provide full protection.

Which engine oil is best for diesel engine?

• Mag 1 Full Synthetic 5W-30 Motor Oil. MAG 1® Full Synthetic 5W-30 is one of the purest and most advanced motor oil products currently available.
• Mobil Super 5W-30 Synthetic Motor Oil.
• Royal Purple Synthetic Motor Oil.
• Castrol EDGE Extended Performance 5W-30.
• Valvoline SynPower 5W-20 Full Synthetic Motor Oil.

Is diesel oil safe for gas engines?

Yes, you can use diesel oil in a gas engine, provided the diesel oil meets the appropriate specifications and viscosity requirements of your engine. For the typical gasoline application, however, a diesel oil isn’t required and the more appropriate choice is a quality gasoline motor oil for both performance and value.

What is API CK-4 oil?

API CK-4 oils are especially effective at sustaining emission control system durability where particulate filters and other advanced after-treatment systems are used. The main physical and chemical requirements for API CK-4 oils are shown below:

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

API CK-4 effectively replaces API CJ-4 and is backward compatible with most applications where currently an API CJ-4 oil is recommended. It requires more from the oils in terms of shear stabilty, oxidation resistance and aeration control than its predecessor.

Can CK-4 oil be used with high sulfur fuel?

However, the use of these oils with greater than 15 ppm sulfur fuel may impact exhaust after-treatment system durability and/or oil drain interval. API CK-4 oils are especially effective at sustaining emission control system durability where particulate filters and other advanced after-treatment systems are used.
