Bukh DV 20 Engine Oil

[christo2024]

The owners manual for my Bukh DV20 says I need a SAE20 oil or 5w-20w multigrade(for ambient temp between + 5deg to +25deg) Its hard to find. Anyone have a contact. Straight SAE 30 seems more widely available. Anyone had problems with SAE 30?

One of my first yachts was a Cinder 22. Loved it. It was called Pheoda. Bought from Brightlingsea, sold it in West Mersea

 

[sailorman]

thats a coincidence, we will start a refit on her in the next few wks. they are a superb sailing boat & look a treat under sail

I was told by the local Bukh man only ever to use SAE30. But other forumites report using multigrades without any apparent problems. They dont like synthetics though presumably because they are pretty basic engines.

he has this evenings bedtime reading /forums/images/graemlins/ooo.gif

Sailed like a dream too. bought new sails for mine. They dont make 'em like that any more ........!

 

[sailorman]

the Cinder was designed by David ( ? ) Westall designer of the 505. that says it all

 

[christo2024]

Thanks oldharry. I'll see what Halfords have in Inverness !!

True. Mouled by Tyler Watson if I remember correctly. Late 1950's early 60's, yes?

I've got a Bukh 20 and use HD30 oil which I can usually get from local motor factors and is spp for diesels, but failing that have also used CC/CD multigrade eg Duckhams Classic without any evident problems. Goes both in engine and ZF gearbox.

 

[tabernacleman]

can someone enlighten me /forums/images/graemlins/grin.gif if an engine designer specifies sae 20 then what harm can I do if I fill it up with sae 10 - 40? I can understand a problem if I use sae 80 too thick /forums/images/graemlins/confused.gif or sae 10 too thin /forums/images/graemlins/laugh.gif but a multigrade - got to be better than a single grade considering the great variety of temperatures we tend to sail in, or motor more to the point /forums/images/graemlins/tongue.gif

In most cases using an appropriate multigrade will not do any harm. Match the API specification advised by the engine manufacturer. Don't be tempted to go for a very low viscosity, I use 15W-40 and would not go to 10 or less. Many classic car owners swear by monogrades but this is to do with additive and detergent content as much as the viscosity.
