For the oil to turn 'milky' it needs to be contaminated with water.

If your cooling system has coolant in it the coolant is not good for the engine oil.

If the cooling system contains straight water - very common here as coolant (for example I use Toyota branded coolant at over 900 THB for 4 liters) then it very well may be caused by your short journeys. 6KM is hardly enuf time to warm up the oil and evaporate the water in the oil.

A good long ride - one to two hours - and check oil then thru the sight glass.

If the 'milky' disappears - you have the cause.

If it persists - then water (coolant) is leaking from the cooling system into the engine.

By the BY - do you have to add water (coolant) ever ?

Those are not the only ways in which you can get water contamination in the oil.  It is reasonably well known that a succession of short journeys can result in a build up of condensation inside an engine.

It may be the fact that you do a lot of relatively short journeys that is causing the slight milkiness of the oil.

I have been buying bike tyres on Lazada for five+ years.  I have never had a problem.  Better choice and lower prices than I can get locally.

The local tyre shop fit them for 40 Baht a tyre.  If it is tubeless I take them to the Honda main dealer and they fit them.  I don't remember what they charged.

I would just run it and keep an eye on the oil to see if any milkiness returns.

Do you do a lot of short journeys on the bike?

The last time I bought the Stihl synthetic 2T was from the Stihl importer but you can get it cheaper on Lazada.

I hate buying the Stihl 2T because of the price but I still do.

OK.

I use a Stihl Chainsaw but one much smaller and less powerful than yours.

When I bought it I ran it on Castrol 2T which was readily available locally.  It was very hard to start but ran fine once started.

On the advice of the Thai importer in Bangkok I switched to Stihl 2T which is very expensive synthetic oil.  No starting problems since then and no issues such as spark plug fouling.  I use the chainsaw infrequently and I think it still has the original plug after ten years.

I cannot think of a rational explanation but this change worked for me.

I don't know, man. That's the equivalent of 75 euros/dollars.

It must be an extremely harsh way of life...

Family support.  And if they don't have that......

What 2T oil are you using?

Young man, there's no need to feel down.

Declining educational standards will have a detrimental effect on the U.K

Why do you think it implies declining educational standards?

Top private schools see their Oxbridge success rate plummet amid diversity drive

 

The Oxbridge success rate of top private schools has dropped by a third in five years amid a drive to boost numbers of disadvantaged students, an investigation by The Telegraph has found.

The impact on private school pupils of targets to increase diversity at the top universities, and an overall rise in numbers of applicants, is laid bare by the findings. 

  Analysis of Oxford and Cambridge offer rates to 50 independent schools with the highest number of applications last year, shows the likelihood of their pupils receiving an offer has dropped from  39 per cent to 26.5 per cent in five years.

Are you suggesting that this is a problem?

I live about 20km north of Chumphon and I travel to Chumphon nearly every day.

I don't think you will be troubled by flooding in this area. 

There has been some rain over the last few days but no torrential rain.  Rivers are high and fast flowing from heavy rain about a week ago but water levels are declining right now.

Thank you for taking the time to post Nigel.  I found your posts very informative.

Of course other than issues of taxation there are other good reasons why it may make sense to deposit income earned abroad in a foreign account.  In my case these are because I do not want or need all my income from abroad coming here and because I can time any transfers to Thailand so that they are made when interest rates are advantageous.  A further consideration is that investment opportunities are much better in my home country than they are here.

How does the OP know what is in the radiator now is the correct coolant? Excessive dilution of coolant or substitution of plain water is a possibility.

The OP should also feel around at the top of the radiator ( inside ) for irregularities such as aggregated rust which should not be there.

I agree with other posters overheating after a coolant change is suspicious.

I'm not sure how coolant gets air in it, being at about 90-110 C in operation. Standard laboratory procedure to degas water is to boil it. Perhaps people floating that hypothesis are confusing engine coolant with brake fluid.

Air gets into the system when the old coolant is drained out.

That air is normally displaced when you refill the cooling system but it is quite common that not all the air is displaced.  Hence the provision on some cars of coolant system bleeding points.  On other cars a specific refilling process will be described in the factory service manual to get rid of air pockets.  Where such a process is set out it should be invariably followed.

On some cars, particularly mid and rear engined cars, the bleeding process involves raising the front of the car higher than the rear.  Of course a Honda City does not fall into that category.

This makes sense.

 

I think it's too much of a coincidence that the problem occurred right after the coolant change.

The bleeding process varies from car to car but I would guess a Honda City falls into the easy category.  Some cars have bleed valves in the system specifically for bleeding air in the coolant.  Whatever the process it would be detailed in the factory service manual.

I think the most likely explanation is that whoever changed the coolant did not bleed air out of the system after filling it.

If that is the case it will be an easy and inexpensive fix.

On our farm of 30 rai I am the only person who drives the tractor.

This is mainly because the tractor is fifty years old and I have the mechanical sympathy to keep it running pretty much for ever.  Others do not.

The property is reasonably secluded but even if I ran into trouble with 'the authorities' I am well prepared to deal with that consequence.

From my experience :

A single mother with two young kids was given a room in a hostel in a rough part of town and she had to check in daily to keep that room and it was over an hours journey to her kids school .

   Another single mother with four kids was given an emergency two bedroom flat and put on the list for a council flat and its estimated that it would be a good few years before she would get close to the top of the list . By that time her kids will be grown up and she would lose her edibility or move down the list .

   A married working couple would stand little chance of getting a council flat (in London)

Single mothers really lose their flavour after a few years.  Better to buy something at the supermarket.
