SYNTHETIC?

What is it and what does it really mean?

The Oxford Dictionary says:
“made by synthesis; manufactured as opposed to produced naturally”

When it comes to oil we think of synthetics as the best that we can buy and that all synthetics are the same but, it’s not so simple.

Synthetic oils are not all the same, some are manmade in laboratories with uniform sized molecules and represent the finest quality that money can buy; others are merely highly refined mineral oils also known as hydrocracked oils.

So, some synthetics are not really synthetics at all in the true sense of the word and certainly not from a chemists point of view. Granted, these highly refined mineral oils have some advantages over less refined mineral oils but they do cost more.

Why are highly refined mineral oils called synthetic and is this legal when they are not really synthetic in the true sense of the word?

A legal battle took place in the USA some years ago and the final ruling was that certain mineral fractions that had undergone extra chemical treatments could be called “synthetic”.

The Marketing Executives were delighted as they realised that “synthetic” could be printed on a can of cheap oil provided that the contents included this specially processed mineral oil which cost a fraction of the price to produce than real synthetics. The profit implications where fairly exciting too!

So how does this affect the average motorist with a standard road going car or bike?

Very little other than you may be paying for something that is not quite what you think it is. Quality-wise it will still be better than that old 20w-50 dino oil in the back of the garage that cost next to nothing.

The economics are pretty simple too. If you like the look of well-marketed can with “synthetic” printed on it that does not cost you a lot, you now know why this is the case.

But, if you have a high performance, modified or track car/bike and you want to keep it in the best condition then you need the real thing as it offers the highest levels of protection. It will cost you more but then it’s still cheap against the cost of an engine failure!

great info, so which brands are good synthetics? which are not so good?
 
in no particular order motul, amsoil and redline are all probably in the good synthetic category with high levels of zinc in their additive packages.

I think Mobil 1 has been the brand that's been clever with their marketing....
 
anybody familiar with Pentosyn? RagingAngel what do you think about Royal Purple or Lucas Synthetic? i really like the lucas stuff but we stock Pentosyn at my old garage so thats what i run...
 
I've never heard of Pentosyn.... there was some discussion a while back about how oils should be as "pure" and free of dyes as possible and although I'm sure Royal Purple's additive packages have changed significantly since then, I can see the validity of tainting their blend with dyes for the sake of marketing.

Lucas seems to be quite popular in the states and I've had mild experience with it, mostly with their transmission stuff which I found to be neither good or bad so I can't form an opinion on it really. Their marketing material was quite ingenious back then with the spinning gears on the counter showing how their oils would cling to the teeth and not foam up.

Another brand that's been popular is Torco and I believe they are one of the oils out there with a very high zinc content ....essential for high temp/high pressure operation.

You get what you pay for generally, price is a pretty good indicator

Real synthetics cost 6-8 times more so, the cheaper they are the more suspect they are.

A few goodies, Silkolene Pro S, Motul 300V, Redline

There are some good US oils, Redline and Amsoil spring to mind but many are just not all they are cracked up to be ;)

Mobil1 is just a petroluem base-stock oil that is refined highly enough to pass as a synthetic. It's not the same. I'm guessing every other "100% synthetic" brand you can get at Autozone does the same thing, but I don't know for sure which ones.

Amsoil, Eneos, Motul, Redline, all these are full synthetics. None of these companies will recommend additives, as it will taint the already balanced oil additive package. For example, Lucas oil stabilizer will cause foaming when put in either a transmission or engine.

Synthetic oil is also refined almost clear, color is added, so royal purple's purple color isn't any worse than a brown color in other synthetics.

the Lucas is clear :nice: i want to try that ENEOS stuff but not sure what weight to use on my turbo civic :( Currently using 5w-40 but they don't have that...
 
Damm ive used the Castrol Magnatec for yrs now, convinced its was within the best!!

Tho now i realise WHY the Castro Edge costs more than double. . . :shocked:
 
what about Valvoline SynPower Full Synthetic? I use it and one time, according to the dipstick, was running for one month with NO OIL!
 
Its ok, middle of the road stuff. Here in the UK it is often seen as cheap and chearfull.

It is a good quality synthetic the 0w-40, it is pao based and one of their premium oils, engines do have a habbit of drinking it.
