winter oil?

[rogerroger]

I'm re-commisioning my engine for the season this w/e - do I need to replace the clean oil I put in at the start of the winter or just make sure there's enough of it ?

Sounds like you have done the right thing i.e. change the oil at the end of the season so the engine overwinters with nice clean oil. There will be no need to change it again yet.

Re:yes !!

The correct way ( well in years gone by ) to winterise, is to firstly flush the engine then drain .
Refill with castrol storage oil, this was the method used to combat the acids present in the oil from eating away at the bearings, but as most engines back then had white metal bearings you could say that apart from the special rust inhibitors in the storage oil that clean oil is clean oil.
I would think you'd be fine as long as you stop the engine from starting while you let the oil pressure rise, at least then the bearings are lubricated prior to running up .

Poxy NE wind all flipping week here in the Wash ,stopping me from going out to play !!

Re:NE Wind

It was quite funny, I got my sons out of bed at 02.15 Monday morning to catch the tide at 0400 ish . They are bloody hard work to get out of bed at any time !!!
Well the Wash seemed fine untill the wind dicided to increase as we were comming to the outer marker of Freemans Channel , I dicided to quit and run for home rather then struggle to get over to the Hunstanton side, also I had visions of it worsening later on, then crossing back over to get home could be even worse.
We wanted to get up to Wells to try a spot of fishing but ho hum.
Mind you now the wind is backing N so maybe tommorow it should be ok.
I bet next week when my boys are back at school the weather will be perfect HA HA so I will just have to go on my own.

I tend to drain off and replenish the sump with cheapo oil at the end of the season, and then drain this off and replace with better stuff in the spring. There can be quite a considerable condensation build up in the sump over the winter.

Roger,

As long as your winter oil is the correct grade for the engine and not a special winter storage oil which is designed to stop corrossion but not for running the engine. Then I agree with the good Doctor you have done the right thing in not leaving old oil in the engine during winter storage. Your oil will not have picked up water of any consequence unless you have an engine/head problem.
The trace amounts of water measured in ppm will be driven off when the oil and engine are hot. Red diesel has more sulphur in it than road diesel, 0.2% against 50 ppm so it is important to use diesel oil which has more anti acid additive to combat the sulphurous acids formed. The upside is that the extra sulphur stops bore scuff so road diesel (white) has an additive to combat the bore scuff problem.
So you can spend the tenner on some more wine!
All the best
Trevor
