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 fa-4 engine oil?

The new FA-4 oils will be offered in lower viscosity grades and are designed primarily for the next generation of diesel engines, to help maximize fuel economy without sacrificing engine protection. FA-4 oils will have limited backwards compatibility.

Is ck4 oil synthetic?

Mobil Delvac 1™ ESP 5W-30 and Mobil Delvac 1™ Advanced Fuel Economy 5W-30 are advanced full synthetic diesel engine oils that provide extended drain capability and exceptional low-temperature performance with the potential to improve fuel economy.

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

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 does API service CK-4 mean?

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.

Can diesel oil be used in gas engines?

Diesel oils have to put up with much higher engine temperatures, higher oxidation rates, sulfur deposits, fuel soot, acids and other deposits and conditions not usually found in automobile engines. …

Is CK4 better than CJ4?

Comparing CK4 vs CJ4 You don’t really need to understand the chemistry to appreciate the benefits of CK4 vs CJ4. 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.

What does CJ4 mean in oil?

CJ-4 Service Category Description. 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.

What does API CH 4 mean?

exhaust emission standards
CH-4. Current. Introduced in 1998. For high-speed, four-stroke engines designed to meet 1998 exhaust emission standards. CH-4 oils are specifically compounded for use with diesel fuels ranging in sulfur content up to 0.5% weight.

Is API SN better than SL?

As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. API SN to SJ are for the most recent cars, API SH to SA for the older cars. In this case, you need API SL, so an API SJ, lower, cannot be good. SM and SN supersedes SL so both oils can be used.

Why is diesel oil so black?

Why is my Diesel Oil Black? So when your mechanic changes the oil in your car, the golden amber liquid is quickly darkened by the residual oil and carbon build-up in the engine. That change in colour is a sign that the oil is actually doing its job.

Can I use 10W 30 instead of 15w40?

Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for a 10W-30 engine oil to protect as well and last as long as a 15W-40.

What kind of oil do I need for a FA-4 engine?

API FA-4 oils provide similar improvements but they are NOT backward compatible with earlier engines. In most cases these oils will only be used in on-highway engines manufactured from 2017 onwards. This specification requires a XW-30 viscosity grade oil with fairly low HTHS viscosity (between 2.9 cP and 3.2 cP).

When to use API CK-4 and FA 4 oils?

It requires more from the oils in terms of shear stabilty, oxidation resistance and aeration control than its predecessor. API FA-4 oils provide similar improvements but they are NOT backward compatible with earlier engines. In most cases these oils will only be used in on-highway engines manufactured from 2017 onwards.

What’s the difference between FA 4 and CJ-4 oil?

Every mile logged helps us further prove the benefits of Mobil Delvac™ CK-4 and FA-4 oils. CK-4 and FA-4 oils both represent an upgrade to CJ-4 oils. CK-4 oils maintain traditional high temperature/high shear (HTHS) viscosity and FA-4 oils are lower HTHS viscosity. Of the two oils, FA-4 oils focus on enhanced fuel efficiency for newer engines.

What’s the difference between PC-11 and FA-4 engine oil?

As PC-11 engine oils get closer to arriving, you may hear the term High Temperature High Shear (HTHS) viscosity. 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.
