my 93

Quoted straight from owners manual and it is a classic, thats not the manual that came with your **** bag. But as you've mentioned it must be as I only have a 110 post count and you with all your keyboard cruising 10k+ post count(Life??? do you have??) so you must be right ALL the time

I must remember to just keep working on my own impreza and not interfere with an old man that has a full time hobby talking crap over the tinternet.

Pete you are an armhole and you posts have gone to prove it.

(MY 93 sits patiently waiting for said sad man to reply.) F**k that I got a life to get back to, enjoy writing your reply PissMyselfLewis if thats not exciting enough for you, you could always take your car 1.6 miles up the road and then back again without going above 2,000 rpm

Look idiot .... you are showing yourself up to be the pratt I know you to be

Read what the starter of the thread said .... I'll put it here as you clearly have intelligence issues (well, lack of it ) here's what the first poster said:-

"My dad has won a free bottel of Shell Helix Ultra Fully Synthetic motor oil 5w-40.

Is this OK to use? The dealer where my dad has it serviced used fully synthetic oil"

They are BOTH Fully Synthetic according to the poster, we ARE talking about a different brand issue then aren't we??

I'm assuming that you cannot help being really stupid, so I'll be gentle on you

What a wally!!

Pete

pslewis

Thats what the Main Dealer used to tell me EVERY service

Honestly ........... they wanted to charge me for the bulb AND for the labour to replace!! do you think I paid up?? Yeah, RIGHT!!

Pete

pslewis

Not sure what rubbish you were spouting there, but, the simple (maybe it's a bit challenging for you?) fact remains that Subaru recommend a service each 6 months or 7500miles - on a Classic.

Your dribbling post doesn't actually make it clear whether you were disputing that fact or just having a pop at an old fella??

They don't recommend it, Pete, I think the sticker on the door says the oil MUST be changed every 6 months or 7500 miles!

it's the LAW!!!

EXACTLY!!!!

I struggle to imagine what kind of mind altering drugs these other idiots are on!!

And whats with "shell helix isnt a true fully synth oil" bollocks?

Taken from Shells website:

Product Description:

Shell Helix Ultra is a unique, fully synthetic lubricant for ultimate engine protection and performance. Founded on Shell technology and Formula 1 racetrack experience over many years, Shell Helix Ultra has been tried, tested and proven even under the most extreme driving conditions.

Not a fully synth oil?....

It's marketing blurb Marc. IIRC Shell is one of serveral 'hydrocracked' mineral oils, the are permitted to be called "fully synth" because they are highly refined. There are not however, true fully synths.

There are several posts about this, with info from qualified Chemists, who are much more knowledgable than I.

Bare in mind Marc, that they are legally allowed to call the oil fully synth!! So will claim it is! If only the search function was working!!

This might help a bit, found it during a very brief search. http://www.pecuniary.com/newsletters...ynthetics.html


People are more than a little surprised when they hear that many oils now on the market that are labeled as “synthetic” are really conventional oils. They are being advertised and labeled as synthetic oil, but are really specially refined conventional petroleum oil. People ask me how these companies can do that.

I first included in this newsletter over a year ago excerpts from an article in Lubricants World Magazine entitled “A Defining Moment for Synthetics” which reviewed the facts and circumstances around the challenge made by Mobile against Castrol’s advertising. In essence, the term “synthetic” was determined to not be a scientific term, but was judged to be a marketing term. The definition of synthetic lubricants was broadened to the use of the term “synthetic” in referring to motor oil that had the ability to provide synthetic performance, but without defining synthetic performance. In other words, beauty is now in the eye of the beholder – but without full disclosure!
Now, as a result of this ruling, many of the labels on motor oils that you see on store shelves that say “synthetic” is not a synthetic (in the classical sense), and could now be what used to be labeled a “synthetic-blend”. According to Lubes n’ Greases magazine (July 2001), “…most large lubricant producers moved quickly to replace PAO with Group III base stocks in their synthetic [passenger car motor oil] formulations.”

It went nicely with my edition of country life!!!

Use what oil you like in your car. I use Silkolene for the reasons stated, if you want to use Shell,Vegtable oil, KY its entire up to you!

He he, I have some intersting finding on using fuel with added Ethanol (such as Tesco unleaded). And the effect it has on the oil (causing Formic Acid, Acetaldehyde and Acetic Acid).

Should scare the ***** when it goes mainstream

Think I might start selling Nitride treated cranks

I've googled and found conflicting stuff on Shell's "special ingredient". Some say it's either Toluene or Ethanol.

But don't worry folkes it's only 5% (E5)...but better change your oil every month, just in case

Before I came on this site I'd have never imagined that OIL of all things would be the most debated and contested topic of all time...it even beats the infamous 'which is faster astra or Scooby'

Perhaps one of these 'oil rants' should be made into a sticky or we should have an oil forum subsection so that newbies may avoid the mistake of falling into this same bear trap time and time again and asking any kind of question about oil - cos they all end up at the same dead end...

That way it may become the biggest thread in the world...

One things for sure - if it raged to a 10000 post thread I bet the whole thing would STILL not get resolved..

So why not a moderated 'THREAD DUEL' - I've seen these on other forums. Two 'experts' one pro synthetic and one 'anti' synthetic get to debate in a single thread for 6 posts each on the subject using as much research and knowledge as they can find ie a serious scientific intelligent debate - then we humble motorists get to VOTE on the winner...

Ahh, good idea, but it'll never get resolved, as different useage needs different oil. What's good for one man may not be any good for another.

Then their is the pseudo synthetics vs. real sythetics. And then is a Pseudo synthtic "that" much better than a semi-synthetic if it uses the same basestock and additive packages

Not to mention the "Thicker is better" vs "Thicker is bad" brigades.

And to cap it off 99% here have no personal catorgorical REPEATABLE proof of what causes every single engine failure they see (and alot probably haven't even seen, yet alone touched an engine's internals) - most often they see sludge and varnish, signs of poor lubrication on bearings and some metal fragments...then always blame the oil - and this happen with literally ALL types of oil. Just the most widely used oil will lose out as that is the one that will see more failure, because its more common (such as Helix and Magnatec ).

Still, would be good fun to watch, I love lurking on topics like these LOL

My advice is CONSISTENLY to follow what Subaru say .... and NOT to get taken in by talk of utter crap .............

The only thing HYDROCRACKED around here are the **** of ScoobyNet - so, yes, by all means .... lets have a sticky that says:-

'For the selection of Oil please follow the manufacturers instructions'

Ignore ALL other advice from the ****, Salesmen and the plain stooooopid

I think this explanation is what you are looking for.

Below is an article written by John Rowland, Silkolene/Fuchs Chief R & D Chemist for 40 years.

Quote:

Costs of synthetics vary considerably. The most expensive are the “Ester” types originally only used in jet engines. These cost 6 to 10 times more than high quality mineral oils.

The cheapest synthetics are not really synthetic at all, from a chemists point of view. These are in fact specially refined light viscosity mineral oils known as “hydrocracked”. These have some advantages over equivalent mineral oils, particularly in lower viscosity motor oils such as 5w-30 or other oils with a low “W” rating such as 5w-50 etc and they cost about 1.5 times more than good quality mineral fractions.

We use several different grades of this base oil, where appropriate. This is the “synthetic” which is always used in cheap oils that are labelled “synthetic”.

Yes it’s a cruel world, you get what you pay for!

Now, you may ask, why are these special mineral oils called “synthetic”?

Well, it was all sorted in a legal battle that took place in the USA about ten years ago. Sound reasons (including evidence from a Nobel Prize winning chemist) were disregarded and the final ruling was that certain mineral bases that had undergone extra chemical treatments could be called “synthetic”.

Needless to say, the marketing executives wet their knickers with pure delight!

They realised that this meant, and still does, that the critical buzz-word “synthetic” could be printed on a can of cheap oil provided that the contents included a few percent of “hydrocracked” mineral oil, at a cost of quite literally a few pence.

So, the chemistry of “synthetics” is complex and so is the politics!

The economics are very simple. If you like the look of a smart well-marketed can with “synthetic” printed on it, fair enough, it will not cost you a lot; and now you know why this is the case.

But, if you drive a high performance car, and you intend to keep it for several years, and maybe do the odd “track day”, then you need a genuine Ester/PAO (Poly Alpha Olefin) synthetic oil.

This oil costs more money to buy, because it costs us a lot of money to make, very simply, you always get what you pay for!

That's the one,

Thanks Simon!

My point was that it's only costing me £14 quid more every six months to go for a high quality synth than a lesser quality item. The way people go on here about "SN *****" on the basis that we use the best quality fully synths etc... you'd think that we were paying hundreds more for something that did not differ in quality.

So, you get a better oil for only just over £2 a month. Seems like a no-brainer to me.

A bar of Tesco Soap at 5p will clean you just as well as a bar of Harrods soap at £5 ................... the Harrods bar may well be nicer, creamier and smell lovely, it may even need replacing less often - BUT they BOTH do the SAME job at the time of use!

And thats my point, BOTH expensive Oils and cheaper quality Oils do the SAME job at the point of use .......................... one might give you a nicer smelling feeling - but, don't kid yourself that it's worth the extra premium!!
