Budget diesel polishing

[Refueler]

Hi Ducked ... strange text format ... ??

Looks like you may have looked online and seen AI response about Lead and deposits ..

My post was based on use of Avgas years ago in car engines that were not automatically advanced / retarded ignitions etc - they were basically fixed for an octane significantly lower than Avgas - which was often over 110 rating ...

With regard to petrol in diesel - many farmers and trucks did that to 'winterise' the fuel - to stop the parafins dropping out and clogging the fuel filters. Nowadays rarely seen as winter diesels are treated for lower temps use ..... only if you still have summer diesel in the tank - a dose of ie 3 - 5% petrol can be used ... in severe cases up to 10%. The other fuel that can be used instead of diesel or as a boost for winter - is Kerosine ....

In arctic conditions diesel is actually DPK .... Dual Purpose Kerosine.

Correct - but the bugs die .. they deposit crap ....

What are you going to do ? Run a 2micron continuously to stop your engine getting 'gunged up' ?? Stopping to change filters every so ofrten ??

The secondary fuel filter is around 2 micron, so that does the job.

On my engine, anyway.

When I got rid of 600 litres of bugged up fuel the inside of the tank, inspected with a mirror on a stick, was covered in black dust-dead bug as you say. Between Gloucester Docks and Falmouth we used £200 quids worth of filters, Racor and OE Yanmar secondary filters.

Strange text format is due to using TWGF's laptop, which really wants to be doing Mandarin and reverts to a primitive Courier apparently spontaneously. Probably magic corrective keystrokes exist but I dont know what they are, though I do know its a PITA.

Re AI, trying to be insulting? Or even more parenoid than I would be if I thought AI　ｈａｄ　ａｃｃｅｓｓ　ｔｏ　ｍｙ　ａｎｅｃｄｏｔａｌ　Ｍａｒｉｎａ　１８００　ｍａｉｎｔｅｎａｎｃｅ　ｓａｇａ　ｆｒｏｍ　ｗａｙ－ｂａｃｋ－ｔｈｅｎ，　ｗｈｅｎ　ｈｕｍａｎ　ｅｒｒｏｒｓ　ｗｅｒｅ　ａｌｌ　ｗｅ　ｈａｄ　ｔｏ　ｗｏｒｒｙ　ａｂｏｕｔ．

Not trying to insult at all and was not about the Marina 1800 engine at all .... it was the mention of :

"though it'd increase deposits and plug fouling, especially if leaded"

Which is what AI says also ...

As to the speling of Kero ... I have to work in the Fuel World and the spelling and terms of many fuels have different depending which market you are working in ... one version that often comes up in my work is actually Kerosin ..... I can add more spellings if you wish that get used depending on location ...

Do you use M16 ??

Maybe change to an Enzyme based that kills and breaks up dead bug .. water etc and it burns in the engine .... much better than relying on filters that just clog up ... just a comment.

They probably think its (a?) gas.

Isn't the English spelling p a r a f f I n? ;0)
