Frequently Asked Questions

Yes, PC-11 engine oils can be used in both on and off-road applications. PC-11A (API CK-4) oils have been designed to cover the needs of both older and newer engines while PC-11B (API FA-4) oils have been designed specifically for newer on-road engines only.

Feedback from engine manufacturers have shown that only some of the on-road Class 8 engine producers will take advantage of new API FA-4 oils at the start of the category.

Off-road OEMs and smaller Class 3-7 type diesel engines will likely continue to use API CK-4 oils, although we expect most to continue recommending SAE 15W-40 oils.

API CK-4 oils are:

  • designed to replace all legacy API C applications
  • suitable for most engines produced prior to 2017

API FA-4 oils:

  • will be introduced for 2017 and future engines
  • allow end users to achieve improved fuel economy over both current SAE 10W-30 and 15W-40 API CJ-4 engine oils
  • may be suitable for use in some older engine designs. Consult your OEM to determine if an API FA-4 oil can be used in an older engine design

Passenger Car OEMs do not recommend heavy duty diesel engine oils for gasoline applications. Diesel engines and their emissions systems are designed differently than gasoline engine systems, especially with respect to the catalytic converter, and using a diesel engine oil in a gasoline engine can be detrimental to the performance of the emissions equipment.

No, however it is highly recommended that you consult the OEM manual to ensure the proper oil is being used.

Many oil pressure sensors are calibrated for an SAE 15W-40 engine oil even though most OEMs now allow 10W-30 oils. If you are switching to a 10W-30, the low pressure warning is likely not revealing an issue, but rather a need for re-calibration, which can be via your OEM service centre. You should not have this issue in current and new trucks because the sensors already take into account the use of SAE 10W-30 engine oils.

Owners of 2017 and newer trucks might be required to use API FA-4 oil if an OEM makes it a requirement. At this point, many OEMs still haven’t announced whether API FA-4 and/or API CK-4 oils will be required for 2017 and newer trucks. It is likely that many fleets and truck owners will be able to use only API CK-4 oils. More will be known closer to December 1, 2016.
