Which oil for 60000 miles Classic Impeza?
I was using Motul 8100 5W-40 - 100% Syntetic and my mechanic reckons its too thin for the age of my engine and may be the result of the engine running a bit rough lately.
So what engine oil do you recommend?

Do you get 10W-40 Semi in Malta?
Because that's what you need.
Forget expensive marketing hype stuff, pay £15 for 5 litres and change every 6 months - sorted.

For the climate in Malta and if you like to use your right foot a bit, then I think you should look at 5w-50 or 10w-50, brand is just subjective, as both grades will be synthetic by default due their broad viscosity range.
5w-50 is quite common in hotter parts of europe, but is rarely found on the shelf in the UK (its too friggin' cold here)
If the engine is sounding rough, different oil won't fix it. It may mask a possible underlying problem; but a different oil will not magically erase all the previous miles of wear and tear.

Well the engine preforms the same, just since I drive it daily I noticed the different tune in the engine. Initially thought it was something with the exhaust, but had it checked.

I had a Calibra once ... a 16V RedTop Engine, sweet unit.
Anyway, someone said that 50 would be good for it ... what a mistake that was!!!
It just sounded like a bag of spanners, seemed sluggish to rev, all in all a disaster!
Changed it once more for a 5W-30 I had used previously .... the sewing machine smoothness was restored immediately - the oil can have a massive effect on an engine.
No need to use 50 or 60 in any engine unless it's use calls for such treacle.

its normally the hydraulic lifters that require a certain grade of, to thick and you wont get full valve lift (like zetecs).
Is 10/40 semi really recommended for turbo subarus? surely a fully synthetic 10/50 (eg mobil1) would be better for a turbo charged engine?

10w40 is recommended, as per most cars, tried and tested on subaru engines with no adverse effects.
Shell helix 10w40 semi synthetic is the recommended oil of Subaru for the Impreza turbo/sti and wrx's.

yes there is a warning in the service manual "5w30 is not recomended for sustained high speed driving" which in my mind also means its no good if you like to thrash the car a bit.

halfords stuff is £21, its been used in my scoobies for years. at least you wont need to the change the filter and think of that oil as a good flush though. it means your new stuff will not be contaminated so quick.

The idea of fully synth is that it doesnt get broken down by the extreme turbo heat and end up as sludge in the oil pick up pipe.
I guess 10/40 semi is fine if you change it often enough..

I'll bite...
But they last longer and are more stable - the long chains in semi will break down under hard use into shorter ones and you'll end up with oil that's not doing what it's supposed to i.e. it stops being multigrade and becomes too thin under abuse. So if you do change more often, THAT empties your bank too, and you don't have the best protection anyway.
It's like saying this leech is perfectly good because it was state of the craft 400 years ago. Well you stick to leeches Pete, I'll have some penicillin

Last longer?
Longer than what? 6 months? 12 months?
My Service Interval is 6 months - it gets changed then as per Subaru's recommendation.
So, paying through the nose for a longer lasting Oil is utterly pointless (as the benefits will never be felt).
It's like buying a long life gob-stopper - even though you always spit them out after 5 minutes!!
