Go to your local garden machinery shop rather than getting is posted. Think it was £48 for 4 x 5 litres when I bought some from my local place last year.

Regarding the original post....what is the difference between mineral, semi and fully ? Oil's oil so how does "synthetic" fit in ?
Exol fully synthetic for me BTW pretty cheap and now in 20L containers.

I have just ordered 20L of the Exol Lubetech Fully Synth for £76 using the discount code se001. Works out at £3.80 per litre with free postage. I think anyone will find that hard to beat for a top spec' fully synth racing oil.

That sounds like a good deal with the free post.

Sold on the Groundsman after seeing Edens fantastic video - man can that scoot go!

is semi-synth deemed thick enough?

I've been using Groundsman in my GT200 kit, no lubrication issues whatsoever

It has nothing to do with viscosity, just the mix of mineral and synthetic components used to make it and the specification that it meets. In the case of both the Lubtech Extol Fully Synth and the Rockoil Groundsman Semi Synth, they both meet the required standards. Use either with complete confidence. I've clocked up a LOT of miles on both but will ne sticking with the Groundsman from now on due to it being as cheap as chips and well and truly proven by Eden

There is of course the question of ethanol creeping into our fuels and I read somewhere in the US on a forum a while back that they had to start using semi-s and full because the ethanol in their fuels just wasted the mineral oil en route to the barrel and thus reduced its lubricating ability. America has a high ethanol content in a lot of their fuels but I have seen a couple signs up here in Britain about some fuels containing it so its something to find out about.

Whether there is truth in this or not I cannot say, I do use Rock Oil city because it was on offer and you kind of get used to a particular brand.

Viscosity = thickness of the oil and it doesn't make any difference to it's ability to lubricate, it gets heavily diluted by petrol after all

Synthetic and semi-synthetic both provide better protection at low temperature, which is when most wear is likely to occur, i.e. start up from cold, let alone the tremendous protection that is provided to high speed running engines. We put small amounts (0.5%) of fully synthetic oil into 4-stroke supercharged engines that run on any fuel mixture containing methanol.

Rock oil Groundsman is the " dogs bollocks " been using it for about 4-5 yrs ,well ever since Eden 1st posted about it never had one bit of trouble with it ............in fact me and a group of mates buy the stuff in bulk , we just had 13 x 25ltr barrels delivered such is our confidence in the stuff

Joe let me know when your ordering your next batch so I can get my order in 1st, had a problem last year getting hold of it at the beginning of the year, had to wait about a month for it to arrive because they had non in stock this years two orders have come in a couple of days though

I'm definitely converted to Groundsman

i bought ours from COLIN BUSH GARDEN MACHINERY he was cheaper than Garritts
Told him we were a Gardening club ,we use it in our Rotorvators
