My engine is using a lot of oil, should I run a thicker oil to reduce this consumption

10 months ago

Running a very thick oil can sometimes cause issues in modern engines. An area that is often overlooked when oil comsumption is a problem is hardened valve stem seals. Oil will bypass hardened seals and allow oil into the combustion chamber via the valve stems. Consumption as high as one litre per thousand kms can be caused by valve stem seal leakage. Nulon Engine Stop Leak can rejuvenate hardened valve stem seals and should be used before moving to a thicker engine oil.
