You may have miss-read one of my previous posts...as this is what I've been trying to get across to them...but the dealer refused to fit my Motul or Mobil oils...I can't understand the mentality...I'm a Pysicist and an Engineer and I used to run a rally car for years and before the days of fully synth AND they played hardball and said it'll invalidate the warranty.....but u always want the best oil u can get in your car...they seem to be very reluctant to allow us as car owners to have a choice in what we fit...
They also said that they had had an engine failure in recent times and were told to hang onto a sample of the engine oil for analysis...could be true, I've no way of knowing, and their claim that a Subaru IM rep had joined in a thread on some buletin board ( they wouldn't name it..) and said that fully synth was not to be used...could also be true...but it could also be a load of balony...I want to get to the bottom of it from a IM perpective...

This oil thing is like a recurring nightmare!
There never seems to be a definitive answer from IM regarding grade and quality/ type. I've never before been in such a quandry as to what oil to use for my next change.
Currently Silkolene Pro S 5-40.
If the importer can't tell you the oil to use such that the engine, treated reasonably, will last for say 150000 miles, what hope?

Have today spoken with IM techno bod.. who basically said
1. No requirement by IM to use any other oil other than those listed in the manual,or supplied by dealer.
2. No memo has been issued to dealers that says not to use Fully Synthetic oil in an Impreza engine.
3. You can use a Fully Synth oil of your choice if you insist, and your warranty should be unaffected by this.
I'm now trying to get this on paper to wave under the nose of the dealer who is obviously swinging the lead ...why bother for the price of a few litres of oil!!!

as someone who's business is independant service/repair/comp. prep/etc established for 7+yrs...........we tend to be quite choosy on oils/components used (in our own and customers cars) as its normally us that pick the pieces up when things go haywire!!
my personal choice (and i currently own 3 subaru turbo's incl. 1 competition car!!) is for only a FULL ester synthetic oil!!
i have never ever seen a car that has 'done its big-ends' thro synth oil'...............i have rebuilt quite a few that have failed because of excess heat and various other problems that probably weren't helped by running poor quality oil!!
its your car and your money BUT why does any motorsport team spend all this money on oils and associated components if its as easy as using chip-fat???
my own recomends are MOTUL and MILLERS oils............won't use anything else...........

Stick with what you're using - it's hard to beat the quality of PRO S.
Motul is another option.

I can assure you that it's not the basestock that's responsible for this, it's more than likely the wrong viscosity being used. If it's not recommended in the book then don't use it.
i.e. If it says 5w-30 or 5w-40, don't use 20w-50!
Dealers know little about the technicalities of oil and tend to blame synthetic as they don't know better!

Use a quality ester/pao and you can't go wrong.
Engines fail due to POOR quality and WRONG viscosity - NOT because the oil is GOOD quality!
Jet engines don't fail (otherwise they'd fall out of the sky) and ester has been used for 30+ years now. Dealer "twaddle" really pi$$es me off!
Dealers should be made to spend time with "oil chemists" as I do on a regular basis and they would soon learn the facts and stop speculating.

LOL mate that made me chuckle, but 2 of the 3 i trust very much as one of them the whole familly run scoobys even at compotition motorsport rally levels, these must know what they are on about( i personally referring to new age not classics) engines are different, but mine is 02 wrx i use 5w - 30 as book says i rag the **** out of it all day long to redline no probs done 13000 miles on this oil i change it every 5000 miles or 3 months which ever first, use subaru filter and fill the filter before fitting dont bother dry cranking, just turn the key and allow to idle, never had a days trouble, all my mates and few customers with scoobs just do the same, not one of them knocked big ends out, 1 in particular over 100,000 miles on the clock has only ever had 10w - 40 semi synth in from new, there is total printed history to the car, from one dealer as x company car, i can honestly say the engine has never been apart, the car is modded and runs on drag strip, has ran 13.009 and runs 13.2 all day long. that is just my findings from what i have seen and heard, i have also spoken to one of the uk,s leading oil company reps whom i know on a personal note, even his tech data does say for classics a 15w - 50 fully syn is reccomended but not on the new age scoobs, so yes think its just down to personal choice but like i have personally seen a subaru impreza 2000 awd uk car ran on 10w - 40 all its life now got 112000 miles on the clock and the engine never been apart ever. my friend in the oil industry is getting me a copy of the results obtained from tests done using different oils etc this should be interesting.

Have now had conversation / exchange of email with IM. Below are responses to my emails...My car is 04 STI
The grade of oil that applies to your Impreza STi is either 5W30, 10W30 or 10W40. 5W30 is preferred.
There is no need to utilise fully synthetic oil in your STi, but should you wish to do so this will not invalidate your warranty.
However, the Mobil 1 15W50 oil mentioned in your e-mail is NOT suitable.
Mobil 1 comes in various guises. As long as the grade is 5W30, 10W30 or 10W40 it will be fine. Ones to avoid are zero rated and above 10W.
I think the bulletin regarding engine oils may have been misread by the dealer!
So thats where IM stand...you CAN use FULLY SYNTH but obviosly some dealers want you to use their oil for profit. 0w rated and 15w rated seem to be frowned upon...as do grades of 50 or above in the high temp rating . I guess that the safe bet if you've a car with warranty left a 10/40 oil...my personal preference anyway....unless you intend subjecting the car to a track day etc where temps will get higher...then 10/50,15/50 is wise...but both of these grades aren't in the IM good books...for road use 10/40 should be fine anyway, so the message is as has been said many times...use the correct oil for the type of use of the car...but don't ask dealers to put in oil which is outside the accepted grades...
For me I still can't believe the attitude of a dealer who says they've had a buletin from IM that clearly they didn't or have decided to miss quote..and who says the grade to use is one that is outside the IM recommended grades, 15/40 infact...IM and the dealers need to get their act together!

There is no need to use fully synth in the same way there is no need to used 98RON, but if you want to get the best out of your engine you'll want to use the best.

That's never been in question...the point was that dealer didn't allow choice of oil in my own car AND deliberatly prevented the use of fully synth quoting an alleged IM buletin...I wanted to know the facts...and now we all know that it's ok to use these oils according to IM....the problem is getting the dealers to use them...This of course only applies if your cars in warranty...you can do what you like when it's not...

I've said all along that 2000 onwards scoobs need 5w and 10w but not to use sae 60's. (5w is definately the best option).
Depending on the car and use you need 5w-30, 5w-40, 10w-30 and 10w-40.
10w's can be semi by nature but all 5w's will be synthetic.
If the car is ragged on track or modded, I've recommended the switch to 10w-50 but only if temps are a problem - Above 130degC!
I posted this some time ago but it pretty much agrees with Subaru UK.
http://bbs.scoobynet.co.uk/showthrea...ghlight=oilman
Always remember that sae 30's are very much a US grade and although available (in certain places) sae 40's are the European equivalent.
5w-40 on later scoobs is always the best option.

right from what a few of you are saying 5w - 40 fully synth is an option for my 02 wrx, which from info gathered here and other places, i agree it is a safe option,the engine now has 32000 miles on the clock, what is the procedure for switching from semi to full is there any thing special to do.
will run mine on fully synth to try it, i have done13000 miles on semi from buying the car, if the motor pops 2.3 to go in so you see i dont mind it popping
which 5w -40 for new age 02 wrx

Jeez, it's complicated nowadays, isn't it?
A lot different from when I was learning to drive (30 years ago!) in my mates dads Austin A30. When it needed oil (as it did frequently!) we were instructed to "get some straight SAE30 - don't bother with that multigrade rubbish".
Not that was much choice when it came to multigrades - the normal multigrades were Castrol GTX or Duckhams Q - both 20w50.

oil man, have found this one which i should be able to get very cheap
A fully-synthetic, high-specification engine oil, providing excellent protection during extremes of operating temperatures and the demands of maximum power. This oil is recommended for drivers who wish to get the best for and from their vehicles. It is suitable for all 4-stroke turbo-charged and naturally-aspirated vehicles, either petrol or diesel.
SAE: 5W/40
Standards: ACEA A3/B3/B4, API SL/CF, GM-LL-B-025
Specifications: BMW (Longlife) 98, MERCEDES BENZ p.229.1/p229.3, PORSCHE, VOLKSWAGEN 502/505,
you may recognise the description, whats your thoughts to the spec it may be very cheep option for me should i ask what the base oil is and make sure it is ester,
how much expect to pay for 25 litres of motul as for mentioned

Brunny,
Can you email me the tech data sheet so that I can look behind the sales blurb and give you a proper answer.
If your're going to go with it ask what the basestock is. DO NOT accept the answer synthetic, it means nothing unless they can tell you what type or basestocks are used ie: PAO/ESTER Group I, II, III, IV or V.
Don't be fobbed off with woolly answers either.
If you want prices for Motul or Silkolene, you'll need to email me.
Hope this helps.
Cheers
Simon
