Wrong oil in Kioti?

[CoenJC]

Ive only just learnt that you need to use special oil for diesel after I've changed my engine oil. The one I've used isn't specified as as SAE and recommends not for heavy duty diesel

Is this a problem? Should I change it?

Yes. As soon as possible.

G'day Cobber... yes, you're going to have to drain that engine oil and put in specific "diesel" engine oil.

You'll have to change the oil filter too.

Lesson learnt Mate.

 

[Thomas]

Don't take the chance drain oil new filter.

 

[Rockbadchild]

yes, I would definitely changed the oil but I personally don't think I would change the filter... but that's me.

 

[Jstpssng]

Ditto to all of the above. Changing the oil is a lot cheaper than premature engine failure.

I don't think it would cause any damage or wear. But I'd change it before using it much longer.
Diesels are made of all the same materials and run at the same temperature as gassers. So diesels have much the same chemical compatibility, viscosity, and lubricity requirements.

My suspicion is that the difference is in the additives. Diesels don't have the problems with high sulphur fuels they used to have, but they still make lots of soot - that's why diesel oil turns black. An additive is put into Diesel oils that disperses soot in the oil so it doesn't clump up and clog passages.

Not worried, we used automotive Rotella 20w-50 in everything for years - gassers and diesels alike. We had zero problems and no noticible wear. Now we know that tests are show there are better oils... like the lower viscosity synthetics for instance. But how much better than no problems and no wear can you get?

Diesel rated oil has specific ingredients (more zinc being one, correct?), and it is designed to keep soot in suspension. Change it and the filter.

I am curious as what is the reasoning for advising on the filter change ?

If he ran the engine after the oil change or if he put oil in the filter during the change, then the incorrect oil is in the filter. If neither of those things occurred, then the filter probably doesn't need to be changed.

I guess I just don't see how that be a big deal, it is minimum amount of oil, I guess one could remove it and drain it out but the life of that oil filter hasn't been affected it is still new.

Depends a lot on the additive package in the oils. Pretty much the reason “they” say not to mix. Could have an unintended reaction.

I would agree that replacing the filter is not necessary. I would remove, drain, and reinstall the existing filter.

Might not be. No real way to tell for sure.

I would change it if for nothing more than warranty security, many manufacturers are going to pull an oil sample if the machine is brought in for warranty work on the engine or related components and you can bet if the oil doesn't meet the specifications there is a better than average chance that they will deny your warranty. I know it sounds a little like the tin foil hat conspiracy theory but there used to be a sign where I worked that read " If it can happen it will happen".

Hmmm.. Oil in a 4 stroke gas engine turns black as well when it's loaded with contaminants.

Interestingly, the oil in my M9's don't turn black as it ages. Just gets progressively darker but never black. I must have good piston rings.

Only diesel engine I've ever seen where the oil turns black quick is a DDEC engine and that is because those engines produce a lot of soot.

 

[Quickster2]

If it were me both oil & filter would get changed without hesitation.

Even at today's inflated prices, oil and filters are the cheapest insurance you can have against engine failure.

Considering the volume of new oil remaining in a drained filter and the volume of the crankcase with the HD oil, I don't see changing the filter either. I'm an oil nut having my first vehicle, used truck purchase as a teen, having a worn out engine for lack of proper oil and changes (47 Chebby 1/2 ton, hot water 6, 3 on the tree)....but one can sit on the fence trying to decide....what is a $7 filter worth?
