Fully synthetic oil versus semi synthetic oil

[Rich Oswald]

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.

hi Rich
i've looked on line to order the oil from a lubetech agent, their price is £84. 90p with free postage.
i cannot see where you can add the discount code but then i'm not the smart cookie

Hi Peejay,

Just wondering about "Lubetech Agent", and why not Lubetech direct? That's maybe why there is no facility to put in the discount code. As said it comes up at checkout,

[peejay]

thanks for info Rich, i'll be giving it a go soon

this is where you buy http://www.lubetechshop.co.uk/

there is discount code offered by another forum you can put in at checkout - or if you ring them they sort it out

....is semi-synth deemed thick enough?

It has nothing to do with viscosity,

is there any detriment to using Synthetic in a standard or mildly-tuned engine?

there's another thread running and apparently it is definitely NOT a good idea. leads to sticky rings, and heavy sooting! among other things

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.

IMHO, it's worth remembering what issue premix ratio is addressing, it is to keep an oil presence inside the engine during use.

For an engine that is continually used at near peak revs it will need a higher ratio of oil than an engine that is running for the majority of the time at a more modest rev range.

With that in mind, as Eden has alluded, to if an engine is not being used hard enough to burn the oil then gummed rings will probably be a consequence.

The top end of a 2 stroke engine will wear better with a good soaking of lighter oil whereas the crank and bearings which will do better with less but heavier oil, the top end is where I reckon the priority lies in the choice and ratio of oil used.

As long as the oil ratio is suitable for the use the engine is put to there is no reason to assume that synthetic or semi synthetic will gum rings and cause sooting any more than a good mineral oil.

That's a little cheeky posting their 'members' forum discount code on another site

nice one.

so, as I buy Synthetic for my tuned 225 (4%), it will be okay to put it in the standard 150 but I should stick to a lower %age?

[sunrisemac]

I can only put down my opinion and the bits I have written before are results that have been found by a lot of research on 2 stroke engines in the past by folk far more knowledgeable than me.

My experience with Lammie engines is limited to the SX150 that I have rebuilt and run in my GP it runs with fully synthetic so far at a ratio of 3% with no apparent problems, I have only done 1300 miles since I rebuilt it but it starts easily, doesn't smoke more than a trace, the plug colour is good with no oily deposits and having examined the bore with a bore scope there are no unusual visible wear marks.

However, I will be trying Groundsman semi synthetic when I run out of fully synthetic on the basis of the evidence shown provided by extensive use by other forum members

this it Eden ?

Just out of interest, has anybody tried this stuff from an oil supplier called Westway Lubricants.

I've just ordered 5 litres, arrived within a day.
I'll give it a try at that price.
JASO FC & FD, which is what Rayspeed specify as the best to use in their advice sheets on 2 stroke oil.

[Trojanexplosion]

is it ok to use 3% oil ratio per litre with the Groundsman semi-synthetic oil or 4%

[Trojanexplosion]

cheers Eden

My god just seen 5lts for £12.21 + vat, i paid £13.75 for 1 ltr of Castrol power 1, i will be changing to groundsman.

Cheers Ian

I doubt you will get an answer. Collector1967 has not been on this site since 2014. Eden promoted this oil a lot but he also hasn't been on here for quite a while.

Wrong link removed . Considering the post was back in 2015 that doesn't seem a bad price today?

[martyn dwane]

i wouldnt buy that , it`s chain and bar oil.

[Toddy]

i wouldnt buy that , it`s chain and bar oil.

Been running it in all my tuned motors for last 3 years no issues but like it has been said oil is peoples preferred choice

[martyn dwane]

Toddy ,i use groundsman but that link isnt for two stroke ,it`s for chain and bar oil.

[Toddy]

Toddy ,i use groundsman buy that link isnt for two stroke ,it`s for chain and bar oil.

I see sorry I didn’t check the link and I buy mine from a reputable source not e bay as there was some dodgy stuff about

[burnside]

I've always bought my Groundsman from Garfitts, gone up in price recently from £4 to £5 a litre but still cheap compared to others. Current prices are £21.09 5l and £79.99 for 20l, + VAT on both of those.

[nickw]

Lol, I didn't check my own link. Garfitts have always been a good price as said above.
