Preferably the sump tank ought to be topped up using the identical make and type of lubricating oil. If the same system is not available, the manufacturer of the essential oil should be contacted for guidance. Topping up the lubricating necessary oil with an equivalent product is generally acceptable provided it is created by the same manufacturer and is produced from the same base oil.
Even though lubricating oil suppliers might suggest topping up with others of oil, this is not suggested by many engine producers. In practice, mixing different sorts of mineral oil together is actually unlikely to be problematical since the base oils used to generate such products are broadly comparable in structure.
However , this kind of action should not be taken unless of course the lubricating oil provider has carried out a match ups test and has confirmed that this oils may be mixed.
Even though it is sometimes possible to mix with each other different types of synthetic oil, this is simply not recommended as it is more difficult to evaluate whether or not synthetic oils tend to be compatible. Mineral oil should never be mixed with artificial oil.
