I agree with both of you. I think better oil is BETTER, but I would also believe what Subaru say in there handbook is fine.... Where Pete is concerned it would be fine seeing as he is a more of a conservative driver... I like to put my foot down from time to time and have aftermarket performance parts.
I use Pro S @ 40 quid a time. very happy with that. I would like it cheaper though.... Oilman...
anyway...... Don't take Pete's bait! i'm sure he is getting kicks right now.. Right Pete!?

Essentially this is like the virgin manager of a sex shop constantly telling hookers to use non-lubricated condoms based on his own solo 'personal usage criteria'
Granted changing the oil every 6000 miles is one solution but as has been said changing an an expensive oil every 6000 miles instead of a cheap oil every 6000 miles probably adds up to about 16 oil changes over 100,000 miles - the cost difference over the lifetime of the engine between a good synthetic and a cheap morris oil being about £200 - really sounds like a very cheap price to remove an element of doubt where there is no hard proof to the contrary other than that of a man whose car never exceeds 2500 rpm and only does 3.2 miles a day...
We are talking about a £20K plus car here...people can spend £200 in a couple of weekends at sainsburys never mind over 10 years of car ownership!
Qualifications are one thing but reality is another...I personally know lots of highly qualified intelligent people who are as dozey as the cows - can't even hang a picture never mind do an oil change...practical knowledge will often overturn speculative theory based on assumption..

My car DOES operate in extreme conditions ..... starts up from cold, drives 1.6miles, engine stopped, repeat 4 times per working day.
Add to that a summer of towing, sometimes in mountainous regions and what was that you were saying???
Be SURE of your facts before posting statements

To imply your car undergoes a seemingly EXCLUSIVE and EXTREME set of driving conditions is not only wrong but highly subjective...it is only extreme in how cruelly under utilised it is..
Fact is...
Most DAILY DRIVERS cars go through this 'extreme' AND more - which rather makes them the NORM rather than less usage being an EXTREME - your logic is flawed though your application of english may be technically correct - you can not use symantics as an argument of proof in science..
Furthermore, not only do 'normal' cars do 1.6 miles and 4 cold starts a day (morning, lunch, evening etc) - they actually keep going and do EVEN more miles...and on top of that - they then do extreme miles at rpm's of 5 and 6K rpm's even higher - shock - on the same oil which unlike yours which has never experienced searing 150K rpm turbo speeds AND has actually had to cope with the tortous 'extreme's of 4 cold starts a day AND high speed burn-off...see the following diagram..See how your car exists in the centre of an ever decreasing circle...on weekends I imagine it exists in an even smaller circle...

I think this thread is due for an oil change now.
When you do it make sure you fill the filter up right to the top and let it soak first. Oh, and put the right grade in for the high temperature running being experienced on 100 posts - continued high temperature running requires an oil with higher viscosity and a greater tolerance to complete bollox contaminating the smooth running of the engine - especially when it goes on boost. And this thread has a lot of boost but sadly not a lot of traction!
PS I bet not many of you knew that Pete wears nail varnish when working on the car

Yet again a reasonable genuine question on oil spoilt by people who think they know about oil.
I don't see any of the well known scooby tuners posting here and I guess quite rightly they can't be bothered to argue why they recommend synthetic oils for Subarus and their experiences on average cheap oils.
The biggest flaw in PSL's argument is that Subarus recommendation is a "minimum" requirement for your protection it's there to stop some halfwit putting Castrol GTX or similar mineral oil in their engine and it carbonising in the turbo, there are always benefits to exceeding Subarus requirement!
On all post 2000 scoobs 5w is recommended and this is never a mineral oil, it's a least a "hydrocracked" synthetic by design as mineral oils cannot achieve the 5w rating.
I have never disagreed that using a 10w-40 semi-synthetic changed a frequent intervals will suffice but there are too many people on scoobynet who do not have stock cars used on the road to simply blanket recommend it, it would be foolhardy and downright irresponsible to do so.
I note that for all the engineers here, there are none in the oil industry and therefore I will leave the last word to John Rowland (Fuchs/Silkolene's Chemist for more than 40 years) and his explanation.
Like it or not THIS IS FACTUAL!
Quote:
Cheaper oils are in the long run a false economy, In the first mile the higher volatility, inferior anti-wear performance and poor temperature resistance of a cheap grade of oil will start to show. Obviously, there will be no immediate effects. The whole point of top quality oil is long-term performance retention, which is particularly valuable to people who actually own the car they drive.
The ‘performance’ enthusiast will want to retain the new-spec BHP figures, and the cost-conscious will want to see good fuel economy with 100,000 on the clock.
Cheap oil, (particularly 10W/40 or thinner) evaporates quickly, and the vapour is drawn into the combustion chambers via the crankcase ventilation system. This means calcium and zinc oxide deposits (from oil additives) which will cause pre-ignition, so the knock sensor retards the ignition, giving less power and poor fuel economy. The deposits also contaminate the exhaust catalyst, leading to high emissions and MOT failure. How much does an average catalyst box cost these days?!

Ironically, I have come to the conclusion that the Amsoil sounds like an awesome product for great piece of mind given my 'extreme' driving conditions. I
I'm going to give Oilman a try...
Cheers Pete...one way or another you've helped me reach this decision
Oilman, will this oil happily do a 10,000 mile 'extreme' cycle or would you still recommend a 6K change ? ( I don't track or race btw but I do like to 'pedal down' when conditions are safe and feasible)

Could a Halfords LawSuit be stopping you??
Or were you annoyed because Halfords were selling FULLY SYNTHETIC at £15 for 5 (yes, thats FIVE) litres??
I can always see right through a salesman ..... not one has conned me yet

You cannot get the mpg you claim on that kind of usage. The car will never be off the automatic choke.
I look forward to your explanation.

If people worded these oil threads, " Will I damage my engine if I put a synthetic 5/40 hydrocracked SL ACEA A3 oil into my standard/ PPP / lightly modified Impreza which is serviced at the manufacturers recommendations" I think the replies quite rightly would be different. The best no doubt exists. What is the best and if you need are a choice for you

There is no evidence .............. as seen on another thread:-
"Fully Synthetic Oils are for those with big spoilers and go-faster stripes, they work as a team"
In other words its like the solid silver speaker wire at £20 a foot ..... some people actually believe it does some good Ha Ha Ha !!!
It's for the stupid, scared and gullible ............... end of

Uhhh... tricky question?
You see, if you were confident enough to do your own research you would certainly take a different approach. As it happens you are a salesman.
I recall seeing the same salesman three times in one year at our plant. Early on he was selling industrial fasteners, a few months later bearings, and not long after that lubricants. And not a professional qualification to his name... simply "sold wot mayd me a livvin".
Monkey see, monkey do.

So, thats about as independant as Oilmans words then
He's a salesman, bless him ......... don't you just love 'em???
And you notice how the fella quoted has been working for Fuchs/Silkolene for MORE THAN 40 YEARS!!! now, how old is this bloke?? and he must be REALLY good at his job as he has been headhunted throughout his life ....... NOT!!!
