Whats new with 2007 engines?

Specific changes differ by individual engine manufacturers.However in general, all 2007 heavy-duty diesel engines will incorporate exhaust after-treatment devices which include a Diesel Particulate Filter (DPF), and some engines will include an oxidation catalyst. 2007 diesel engines will also require the use of Ultra-Low Sulphur Diesel (ULSD) fuel.

Depending on the engine manufacturer and vehicle design, some new engines will run hotter than current engines. As well, some engines will utilize higher levels of EGR (Exhaust Gas Recirculation) or CGI (Clean Gas Induction) to help meet exhaust emission requirements.

What happens if I put an API CI-4 Plus oil in a 2007 engine?

If an API CI-4 PLUS oil is used in a 2007 engine, the service interval for the DPF could be compromised as the higher ash-containing API CI-4 PLUS oil will result in more rapid blocking of the filter. The CI-4 PLUS oils may also not be able to withstand the more severe environment within the 2007 engines (higher temperatures, more EGR), which could result in premature oil thickening, sludge formation and resultant wear and corrosion. API CJ-4 oils are designed to provide the improved wear protection, high temperature oxidation control and soot handling required by the new engines.

Are API CI-4 PLUS and API CJ-4 oils compatible?

Yes. API CI-4 PLUS and API CJ-4 oils are compatible, so they can be mixed without fear of adverse chemical reactions causing deposits or additive fall-out. However, mixing in API CI-4 PLUS oils (e.g., for top-off) can result in reduced performance of the oil, as API CJ-4 oils offer higher levels of protection than API CI-4 PLUS oils.

Can I mix the two oils?

API CJ-4 and API CI-4 PLUS oils are compatible with each other. However, Shell does not recommend actively mixing the two products, as there are differences that will be evident in the used oil analysis and a potential reduction in levels of protection compared to API CJ-4 oils.

Can I top off API CJ-4 oils with API CI-4 PLUS oils?

Yes and No. Typically, topping-off an API CJ-4 product with an API CI-4 PLUS oil is not recommended. However, there are some exceptions depending on the model year of the engine. For example, if you are using API CJ-4 oil in pre-2007 engines, you can top off with an API CI-4 PLUS oil if necessary. API CI-4 PLUS oils meet all the requirements for pre-2007 engines. In 2007 model year engines, API CJ-4 oils must be used and you should not top off with an API CI-4 PLUS oil. However, if the choice is low oil level or using API CI-4 PLUS oil, then add the API CI-4 PLUS oil, but change the oil as soon as possible.

Will my warranty be affected if I dont use API CJ-4 oils?

These new oils were designed for use in 2007 on-highway emission-controlled engines. Engine oil recommendations and warranty policies vary by manufacturer. Consult your operations and maintenance manuals for guidance for your specific hardware and application.

When changing my engine from API CI-4 PLUS oil to API CJ-4 oil, how many flushes do I need to do when changing over?

When changing your oil from API CI-4 PLUS to API CJ-4, it is not necessary to flush your engine Shell has designed the two oils to be compatible with each other. As well, Shell RotellaT API CJ-4 engine oil can be used for top-off in your truck if you are using Shell Rotella T API CI-4 PLUS engine oil in pre-2007 engines.

When switching my bulk tank from API CI-4 PLUS oil to API CJ-4 oil, how far down do I have to drain before it can be considered API CJ-4?

When switching from API CI-4 PLUS oil to API CJ-4 oil, we recommend draining your tank to 10%.

Are there any special HSSE or used oil disposal procedures needed for the new oils?

The disposal of the new Shell Rotella T engine oil is the same as the older version. Check with your local authorities on the proper disposal of used engine oil in your area.

What differences and advantages will I find in switching to the new API CJ-4 oil?

In 2007 model year engines, API CJ-4 oil will be required to protect the engine and allow for maximum durability of the exhaust after-treatment system.

In pre-2007 engines, API CJ-4 oil will provide the latest in protection, including improved wear protection, high temperature oxidation control and soot handling, which will enhance engine durability and cleanliness of the engine.

Will I see any difference in oil consumption in my equipment?

We do not anticipate any difference in oil consumption with Shell Rotella T API CJ-4 engine oil. Shell Rotella T oil has used 100% group II base oil for years. Group II base oils have very good volatility. Our new API CJ-4 Shell Rotella T engine oil continues to use 100% group II base oil.

Will the customer see any differences when they change to API CJ-4 oils?

If you are conducting used oil analysis, you will see a difference in the concentration of the additive metals.

Does the new oil look or smell any different?

Colour is slightly different and there is a distinct, non-offensive odour in the new API CJ-4 oil.

Have mineral oil based and synthetic oils changed at the same time?

Shell introduced its API CJ-4 mineral oil based formulations in 2006. Our synthetic products will be introduced in 2007.

In what package sizes will I be able to purchase Shell API CJ-4 engine oils?

Shell Rotella T API CJ-4 engine oil is available in bulk, tote, drum, pail, 4L and 946 ml packages. Shell Rimula SuperCJ-4 oil is available in drum and pail packages only.

Where can I purchase Shell Rotella API CJ-4 engine oil?

Shell Rotella T API CJ-4 engine oils are available through your Shell distributor or at your local retail outlet where you currently purchase Shell Rotella T products. Visit our website, www.shell.ca/rotella, for more information.

Will API CI-4 PLUS products still be available?

Rotella T heavy-duty engine oil will only be available as an API CJ-4 product Shell is committed to providing products

and solutions required by our customers. However, Shell will continue to produce API CI-4 PLUS products under the Rimula brand if there is sufficient demand from our customers. It is important to note that API CJ-4 oils provide improved performance versus API CI-4 PLUS oils.

Does the Shell Rotella T API CJ-4 engine oil contain less zinc?

Yes. The API CJ-4 (next generation) Shell Rotella T multigrade engine oil has a slightly lower level of zinc than the API CI-4 PLUS Shell Rotella T oil. Zinc is typically used as part of the anti-wear system within the oil.

However, less zinc in API CJ-4 oils compared with API CI-4 PLUS oils does not mean increased wear. In fact, wear protection is one of the key areas where the API CJ-4 category provides improvements over API CI-4 PLUS oils. (Other areas of improvement include oxidation stability and soot control). The new Shell Rotella T API CJ-4 engine oil also meets the requirements of earlier API performance categories, including API CI-4 PLUS, CI-4, CH-4, CG-4, as well as others, and can be used in engines specifying any of these performance categories.

Can I use Shells API CJ-4 engine oils for my off-highway equipment?

Yes. Shells API CJ-4 heavy-duty engine oils are designed to be suitable for use in off-highway equipment of all ages.

Some concern has been voiced that the higher fuel sulphur levels encountered in off-highway applications may require the continued use of API CI-4 PLUS oils. This is not true: In2007, the fuel sulphur levels for off-highway equipment will be reduced to 500 parts per million (ppm) the same as todays on-highway standard. Shell has demonstrated the performance and suitability of our API CJ-4 oils in millions of miles of testing using conventional
