Reply to "No more change of engine oil"

Gents

I think that Mr Prabhakar is trying to extend the drain period of oil but that doesn't conclude No more change of engine oil.

A few OEMs conducted trials with similiar filters but haven't commercialised this concept.

Oxidation is doubled with every 10'C increase in temperature beyond 60'C-Engine oil operating temperature is 150'c and beyond. Oxidation practically changes the molecular CH structure of lubricants.The long chains break down into smaller chains.

The question that I would pose to Prabhakar are:-

How is Oxidation controlled in the continuous duty off highway equipments?

Whether any catalyst is being used to reform the molecular structure of the lubricants in the filteration system?

As Hussain indicated normally lube suppliers have extended drains in medium speed engines that use weak dispersents that release the contaminants dispersed in engine oil, but I am not sure whether a high speed engine oil would release the contaminants as indicated by Mr Prabhakar. I leave it to the forum to elaborate on that issue.

Finally to conlcude ,we have supplied turbine oils running for 16 years but the opearting condition there is completely different with huge sumps of 35 barrels that could replendish the additive dosage through top up.

I feel that in this case the top up of engine oil per 100 litres of diesel consumed should be 4 to 6 ltrs ( Due to serparation of contaminants) in a 35 litre sump,that means for every 600 ltrs of diesel consumed the engine is completely renewed. If that be the case then "No more change in engine oil is required"

My one cent to the issued raised.

We have supplied lubricants and executed condition monitoring for TISCO mines earlier.

In case you want to test your used oil you can contact me at : frankyxavier@yahoo.co.uk.

We can also look at suppling high performance oil API CI-4 Plus which would add value to your statement .
