Engine and gear oil in bulk?

We have a group with 6 RIB's between us. I was wondering if it's possible to buy larger quantities of engine and gear oil to save a bit of money.

Can you buy engine oil in 25 litre quantities? Gear oil in 5 or 10 litre?

I have had a quick google but can't find any suppliers of "bulk" engine and gear oil in the UK.

Anyone done this?

There's plenty of them, I buy all my oils in bulk, nowadays it's usually 20lts or 205lts, often, 20lts is cheaper and ebay can be your friend. Try Opie Oils for starters. I buy some of my Mobil lubricants from Germany, it's cheaper and DPD gets them here just a quickly as buying in the UK. https://www.mein-motoroelshop.de/

You may have local suppliers close to you, Castrol, Shell, Mobil, Fuchs etc. Go to their websites and look for distributors in your region

Thanks for the info.

From looking at those websites, they are all selling "standard" motor oil, not "marine" such as that is branded as Yamalube or Mercruiser. I guess that is no difference at all and all the waffle about it being designed for an outboard etc. is just snake oil?

Yes and no. There is no official outboard marine spec from either API or ACEA and years ago the outboard manufacturers wanted one so they came up with their own, the TCW spec, or TCW3 as we are now on.


The spec focuses on stuff like sticking rings, corrosion and these sorts of things. In the UK and in most of Europe we have good quality oils, so finding a quality oil that meets the TCW3 spec is not a problem may it be yamalube, quicksilver or from just an oil brand of which we have many in the UK. Some oil brands I know will use their same motorbike two stroke oil and rebrand it as a 2t marine oil with the TCW3 spec, the reason for this is any good quality bike 2 stroke oil should smash the requirements for an oil to meet the TCW3 spec. So it is really aimed at parts of the world where quality lubricants maybe harder to come by to try to stop people using oils that are too poor in quality.



Cheers,


Guy

Are you saying the "outboards run cooler than bikes" and therefore require different oil argument is a myth? & that a bike 2 stroke oil out surpasses a tcw3 oil?
I have always had my doubts that an FC-W 4 stroke oil was any better than its automotive counterpart but I've always stuck with tcw3 for my two strokes
Be interesting to hear from an oil expert

Haha I have not heard of that one! Not being a fourstroke man. But yeah, that one is a myth. Having had a quick look at the tests for FC-W4 there is nothing in there that would account for an engine running cooler just all the same stuff a test for an automotive engine oil would go through. From memory the requirements to meet FC-W4 and TCW-3 are not that high, so the oil does not have to be that great. One of the reasons for this, is they sell their outboards globally and no point having them in a area of the world where they cannot produce an oil at a reasonable cost to meet a super high spec. And if you had an engine that really did require a really really specific oil it would also put off the purchaser.

Yeah pretty much, TCW3 come from bike oils, they did not develop a special outboard 2t oil. The outboard manufacturers created a spec, based on some tests. If you are an oil blender and you submit your bike 2 stroke for the tcw3 test and it passes, then it suddenly becomes a marine oil. From a marketing perspective


One thing to add here, is as we are in the UK we have quite tough regulation on our oils, so by default from a global perspective they are pretty good. If you were a pirate in Somalia finding a genuine tcw3 approved oil might be more tricky and important.

If the engine is under warranty then definitely use an approved oil. And you are correct the FC-W4 is no better than an automotive engine oil if you are comparing like for like. As they are readily available here in the UK, no need not to use an FC-W4 or TCW3 as it is good for peace of mind as the consumer knows it is suitable. In my outboards I run the Fuchs Titan Marine Comp 2t, which is the Silkolene Comp2 in another bottle with the TCW3 spec added.


Cheers,


Guy

That has pretty well always been my stance. Cheaper, less known brands or non-marine oils "may" be fine but I'd rather not be conducting that trial myself however small the chance of failure.
