Has anyone used this on their boat engines?
Anyone have any experience of using it?

I have read a lot about it and they say it mixes with mineral and synthetic oils and gearbox oil.

They say it improves lubrication and stops leaks etc.

I am going to put some in my old landy gearbox now and engine (when I do an oil change) because the Lucas steering box additive DID stop my steering box from leaking (for years) and saved me renewing the steering box.

I am still a bit dubious however, but if the gearbox keeps working and the landy stops dripping from the transfer box and gear box then I'll believe in it.

I wonder how it is different from chainsaw oil? Visually it appears the same; very 'stringy'.

Just thought it may be of use to keep inboards living longer ?

I have no affiliation to Lucas (alas).

Then just use your chainsaw oil, it will be cheaper.

I wouldn't do that even to my old landy without a chemical analysis (or at least a fair bit of testing myself) showing that chainsaw oil is the same as Lucas stuff. Lucas state their oil WILL mix with any other oil and do other wonderful things.

Time will tell; if no more drips, then good. If gears all sound fine and engine is quieter and carbon build up less etc, good too.

For all I know, it may be cheaper than chainsaw oil.

I thought it may be of use to those with inboard engines (I only have an outboard).

That's putting it a bit strongly ..... but I must say that I would never try it. However, until a year ago I would have never tried head gasket sealant but I did .... and it worked!

I've spent the last few weeks replacing all the crankcase, gearbox and transfer box oil seals on a Series 3 Landy because I suspect that is really the only way to stop the leaks .... for a while, at least. However, I've also taken the opportunity to do some drilling and tapping to change the crankcase design to something which the Landrover engineers should really have thought through themselves such that another oil seal replacement will be a much simpler job next time! :encouragement:

The link the OP gave describes it as "Number one in the heavy duty and high performance industries", which doesn't exactly describe the typical leisure boat engine.

That is a not a helpful or scientific response. I KNOW the lucas power steering stop leak works (for years).

So without a scientifically based or experience based reply I will be using the stuff mentioned in OP.

As for donk donk engines, if it does as it states, it should make marine engines last longer. Lucas offer a different stabilizer for high performance car engines.

It is also marketed as a "preventative", so would be no use to "ultra-thick" people that have a new engine with no problems to fix. It may however make the engine last twice as long.

Based upon this video, there is less wear on the Lucas Oil mix compared to oil only. Not a brilliant test, but good enough for me on my old Landy. I would not put it in a newer engine without a lot more research.

In the 'good old days' not long after WW2 there were many elderly cars on the market and plenty of Arthur Daleys wishing to sell them to susceptible customers. Many dodges were used to tame ancient mechanicals, including sawdust in differentials, nylon stockings and/or very viscous oil in engines and geaboxes to both quieten them and reduce leakage. I cannot help thinking that this stuff is the modern equivalent.
 
I'm sceptical about additives, but Lucas is a well respected brand for lubricants. Their waterproof bearing grease seems very good.
The documentation from Lucas suggests it is basically a synthetic oil, formualted as an additive for 'normal' oils.
I suspect the same or greater benefit could be had by using an oil mixed in the factory from either synthetic or semi-synthetic stock.
That way you would know what viscosity you were getting.

Some synthetic oils are better at sticking to metals, so more is retained on the surfaces while the motor isn't running. This helps with start up and can also reduce seals and gaskets drying out. Doesn't always work, some synth oils are alleged to go straight through e.g. cork seals which work fine with dynosaur-based oil.

There are also 'seal rejuvenating' additives which soften very tired oilseals. Particulary relevant to motorcycle fork seals. New lease of life, but 'lease' is the word, the soft seal will wear in time.
 
A lease of life is all she needs.

She started out as 2 knackered landrovers, and I built one decent one out of the two. Changed colours a few times. Changed a lot of things over time. Note the XCL tyres for a bit of extra height. Inside was immaculate.
She has been known to be one the end of a lot of swearing until I started replacing nuts and bolts with stainless ones, and I should have a record for throwing a spanner the greatest distance known to man.

I thought the rules on here were not to say something you would not say to someone's face? If you knew me, you may perhaps say it as a joke. You don't know me. You have not included a smiley which may have meant your post was in jest.

Your response could therefore be construed as rude.

The original post was:

Has anyone used this on their boat engines?
Anyone have any experience of using it?

Seems no one has experience of it. I thought it was simply the Lounge where people disregarded the subject of the thread and were rude.

VivCox, much respected on this forum stated his opinion (similar to yours) but in a polite manner.

Seems I will be the first on this forum to actually experience the product. The youtube video showing the correct ratio mix seems to show that the stuff does reduce wear.

I will assume no one will be interested in my findings; at least no one that has replied. So if my leaks stop and I can feel better gear uptake, I won't bother you with facts.

I simply don't understand why people have to be rude. Lead, follow or get out of the way.

I thought my post #5 was constructive and I would be interested. :confused:

Way back in the early 1960s I lived in California and bought a 1957 Ford Fairlane 500. The auto gearbox soon developed a leak at the rear which I cured by adding some oil seal softening liquid. No more leaks for the nearly 2 years that I owned it before returning to Blighty.
 
Lucas transmission fix is v popular with P38 Range Rovers for getting rid of lumpy changes on the automatic gearbox. Having used it I did find that it improves matters and the 'box kept going for another 20k miles before Mr Scrappy took the car away
