The difference between adding additives to your existing engine/hydraulic/compressor oil and using Rye Oil’s flushing oil is:
Rye Oil Ltd’s engine flushing oil is extremely thin oil and will be able to get into partially blocked, thin passages without any issues and remove the accumulated gunk as well. Were as adding additives to your existing oil doesn’t really change the viscosity of the oil. This means that it clean out those narrow passages in the engine. You will also need to check the additive package against your engine oil to make sure there won’t be a chemical reaction between the two. I will add that there normally isn’t, but there is a chance, and why risk it. Another reason to drain your old oil and use flushing oil is if your oil is already holding a lot of contaminant in suspension, if the oil filter is reaching its filtering capacity, then you might to more harm than good using additives.
Because we blend the lubricants ourselves we can offer a non-detergent flushing oil if requested before you purchase. The non-detergent flushing oil would be for any engines or machinery with any phosphorus, bronze bearings or parts(white metals). If a degerent flushing oil was used in that situation it would react and eat away at those parts.
