Saving Old Seagulls

Googled it. At $385 for a 20 litre drum it's worth more than my whole collection of Seagulls. Does it come in 2 litre bottles too? Couldn't see them. I'll have to find a Shell dealer.

You did better than me my best price was for a 44 gallon drum of the stuff.
That was frightening. 20ltr is the smallest i can find on the net.
and thats about $20 a ltr. we ned to find a ship yard that will fill our own bottles for a resonable price.
Any ideas ?

where is the oil that john sells sourced from

I suppose 90 or 140 is not available in your are?
Mixing 90 with cheap yellow grease and some experimenting to see if it will continue acting as a unified mixture with water?

140 is available as penrite transoil 140 but have found out it is not suitable

Most Industrial lube companies stock SAE140, 220, & some 320 & 460.

These are the gear oils I use and pretty cheap too, I only pay £19 for 5 litres from my local suppliers. They also do an SAE460 but that comes only in 20 litre cans.

Not automotive stuff, rock crushers, car bailers, timber shredders,shipping channel dredgers & don't tell them you only want 1 liter, just ask fro a sample to see if it will suit your application, I was given 2 litres of SAE460 & that was perfect for Marston boxes!

It stayed in there & flows!

These guys also do SAE460 and SAE680!! Thick stuff....only in bulk though.

Sorry Rene I didn't read your post all the way through.

This very useful information about extremely viscous oils will certainly help with the problem of leaky old gearboxes. I have got a few examples of those!
However, it had me wondering - although dreaming might be more accurate – about what the oil grade would be if there was no leakage problem.
Assuming:-
1. Good bearings and gears.
2. Zero leakage in and out.
3. A stable oil temperature the same as the sea temperature at say, 10°C.

Under these conditions are there advantages in using a low viscosity grade such as SAE70?

Hi,
I think I will stick to 90 oil, as I haven't had much of an issue , with oil loss. I don't use my motors that much, but after a few hours use over 3 or 4 days, the oil is thick and well emulsified. Usually after a few days at home, I will drain it out, and refill with clean oil. I have yet to see any water separation, even after letting it sit for several weeks.

What brand of the 90 oil do you use?

Sorry for the late reply. It has been a while, and I have thrown out my old oil containers. I usually just get Shell or Castrol 90 gear oil. What ever is on sale at the time. A 4 litre pack lasts me a fair while.
