Synthetic is what it says on the tin it's what it is, artificial, man made, therefore there's NO mineral oil in it!!!

Not true I am afraid.

a lot of the cheaper synthetic oils (£20-40 for 5L) are hydrocracked carbon which is where they take the petrolium basestock (mineral oil) and break it down so its very pure. Its because of this they can be classed as 'Synthetic'. The only true synthetic oils are the PAO or Ester synthetics which are 100% man made and are reguarded as the premium oils (although I am sure Charles will disagree ;) ) and will set you back around £40-50 for 5L. These of course are not recommended for most Landys as they are far too advanced and it is wasting your money.

PAO's still come from mineral oil. The following may make sense to you:

"Synthetics

Despite their name, most synthetic derived motor oils (ie Mobil 1, Castrol Formula RS etc ) are actually derived from mineral oils - they are mostly Polyalphaolifins and these come from the purest part of the mineral oil refraction process, the gas. PAO oils will mix with normal mineral oils which means Joe public can add synthetic to his mineral, or mineral to his synthetic without his car engine seizing up (although I've heard Mobil 1 is actually made by reformulating ethanol).
The most stable bases are polyol-ester. When I say 'stable' I mean 'less likely to react adversely with other compounds.' Synthetic oil bases tend not to contain reactive carbon atoms for this reason. Reactive carbon has a tendency to combine with oxygen creating an acid. As you can imagine, in an oil, this would be A Bad Thing. So think of synthetic oils as custom-built oils. They're designed to do the job efficiently but without any of the excess baggage that can accompany mineral based oils.

Pure synthetics

Pure synthetic oils (polyalkyleneglycol) are the types used almost exclusively within the industrial sector in polyglycol gearbox oils for heavily loaded gearboxes. These are typically concocted by intelligent blokes in white lab coats. These chaps break apart the molecules that make up a variety of substances, like vegetable and animal oils, and then recombine the individual atoms that make up those molecules to build new, synthetic molecules. This process allows the chemists to actually "fine tune" the molecules as they build them. Clever stuff. But Polyglycols don't mix with normal mineral oils."

It's made out of paraffin

stick it in the fuel tank

i certainly wouldn't use it on a baby, petroleum products are not good for humans

if charlesy thinks the oil companies earn money out of expensive lube oils then he should look into what in his soap, shampoo, suncream, moisturising cream(ok maybe not moisturiser ;)) etc

something to look into

The substance "Liquid Paraffin" has nothing to do with Kerosene aka paraffin oil.
 
I'm with Charles on this one - shorter change intervals of a cheap oil is better than longer intervals of an expensive one - common sense says so! You want to get as much of that crap out of the engine, as often as you can to keep it nice and clean inside! You don't need a degree to be able to understand that, surely?

Its not just about getting the crap out though, its about protecting the engine whilst its running ;)

May I equally politely point out this bit at the bottom of that article:

"About The Author

Ed Newman is Marketing Manager for AMSOIL INC., manufacturer of the original synthetic motor oil for automotive applications. He has published more than 200 articles as a freelance writer on a wide range of important topics.
[email protected]"

The author is a marketing manager for an oil company... it's hardly going to be a balanced and objective view is it? Couple that with the fact that I've yet to meet anyone in marketing who knows the barest detail about anything other than how to spin stuff so it sells and I'm loathe to take his point of view as gospel, or even vaguely accurate. Sounds good though doesn't it?

Yep, it would have to be independant of the oil or motor industry, just the facts.

I'm gonna try snake-oil mixed 50/50 with chip-fat i think:doh:
