Engine Oil
Been doing regular checks on fluids since getting my52 bugeye in February. Engine oil has gone down by about a third on stick. What oil make/grade would you recommend.
Thanks in advance.

You need to know whats been put in it B4 if your topping it up as you shouldn't mix oils with different API classification (quality) or SAE viscosity (thickness). Its a bit like mixing the wrong cocktails, they will curdle.
If your unsure whats in it do an oil and filter change. Run your car up for 5-10 mins with an engine flush before draining.
As scoobies run quite hot, genraly at speed and are turbo performance cars I wouldn't recommend a thin oil, I.d go for something like 10W30 or 10W40 Fully synthetic with API of SJ or SH. Any brand with this API is deemed a good oil but I wouldn't go with Halfords own if you get my drift!

SL is an acceptable quality oil. Anything prior to that will be out of date and will not offer the level protection of SL or SM oils offer today. Flushing is unecessary as long as your car has undergone regular oil changes

Curdle!! (Visions of bubbles appearing at the neck of the oil filler cap
)
Although ideally you should have one make in the sump, it is acceptable to mix different makes and grades (viscosity index) with little or no detremental effects. If you don't know what's in the sump, use a good quality semi-synthetic 10w/40. Then, at the next service, make sure you know what's been put in, maybe even ask for a litre for topping-up.
The notion of not mixing oils stems from many years ago when caster based oils (eg Castrol R) could not be mixed with mineral based.

ask opie oils they will even recomend an oil for your car based on your mods aswell for ultimate protection!
ester based fully sythetic oils are best 10w40 iirc
brands like silkolene, motul,millers & gulf are recomended!

I've used Wurths oil flush in mine with no problems and for the past 6yrs used it in every service we carry out at the garage and not once had reports of damage to vehicles. We put it and leave the cars idling for 5-10 mins then drain.
In Wurths own words:
Synthetic and semi synthetic oils are used in most of today's vehicle engines. These types of oil keep their viscosity for longer and helps to prevents "black sludge" building up. However, one apparent weakness of synthetic and semi synthetic oils is that they are not as soluble as the old mineral oil so it doesn't absorb the by-products of combustion (dirt and particles) as well.
If these particles are left to build up they can start to clog oil ways, starving the engine of vital oil. This can lead to premature wear and failure.
Würth engine flush has the following properties:
* Active surfactants to thin the old oil; break down sludge and particle build up to ensure maximum drainage.
* A detergent to clean away residues, unclog oil ways and neutralise crankcase acids.
* A lubricant, Organic Molybolan Compound, to protect the engine while the solvents and detergents are cleaning.
Still my choice, your choice.

Not recommended for use in subaru engines, you can ask the engine builders why 
And a good semi synth or fully synth oil will keep your engine free from build up with regular oil changes
