Question: Will NMF increase oil pressure?
Answer: No. However, NMF will improve oil flow.
Question: My oil pressure decreased. Is this normal?
Answer: As NMF cleans the engine, it improves oil flow and you may see a moderate and harmless drop in oil pressure. Performance should be good. If the engine was very dirty, much sludge may be suspended in the oil. If oil pressure drops significantly, your oil filter may be clogged and changing it should raise your oil pressure to optimal levels. If it does not, there may be so much sludge in the oil that you need an oil change (this is extremely rare).
