Hi
From memory, the Forester STi doesn't have a plated rear diff (it's not listed on UK oil databases), so I would use a 75w-90 GL5 oil.
http://www.opieoils.co.uk/c-673-75w-...ion-fluid.aspx
The Fuchs Syn 5, Millers CRX, Red Line 75w-90 GL5, Motul Gear 300, Amsoil Severe Gear and Gulf Competition are ideal. The Fuchs Sintopoid, Castrol Syntrax Longlife, Millers TRX, Motul Motylgear, Mobil SHC and Gulf Syngear are also good choices.
Cheers
Tim

You wouldnt happen to know how much power steering fluid I would need to do a flush?

Hi
I would use a 5w-40
http://www.opieoils.co.uk/c-656-5w-40.aspx
Out of those, the best ones are the Fuchs/Silkolene Pro S, Millers CFS/CFS NT+, Motul Sport/300V, Red Line and Gulf Competition. The Motul 8100 X-Cess, Millers XF Longlife, Castrol Edge/Magnatec, Fuchs GT1 XTL/Supersyn, Shell Helix and Mobil Super 3000 are good, cheaper alternatives.
Cheers

Hi mr oil man ✋.
I took your previous advice and ran the millers cfs nanodrive 10-50 in my 97 sti, lightly modified. Ran great thanks !
i see you sell the redline high performance oil. Is this any better than the cfs nanodrive for fast road use?
Cost is not an issue - I just want the best performing oil against engine wear .
Also - my car does 2000 miles a year over the summer and then sits in the garage September to April. Am I best leaving the oil changed till the April rather than doing it every six months religiously?
The oil wa last changed end of August last year so prob due a change now but thinking it would be a waste of money for a couple of months of use before it goes away- done 1000 miles since last change
thanks!

Hi
Glad it worked well for you.
Red Line is top stuff too, but I wouldn't say there is any advantage. Both are high performance ester oils, so there isn't a huge difference, except the Millers has the Nanodrive additive.
A lot of people would say to change the oil before the car goes away, but as it is doing so few miles, the oil will be fine for storage, and I'd give it the fresh oil in the new year.
Cheers

Thanks oil man. Ordered more nanodrive from you guys and replaced the oil. Not worth the chance since I’ll be running it next few months.
Will drop you an order come March !

Subaru forester
I ran my car out of oil and now it will turn over but not start what would be wrong with it ?
I get asked many questions about oil so I thought a thread here for all oil related questions would be a good idea and build into a FAQ or reference point for others.
So, put your oil questions here but please give the following information if you would like a recommendation:
Make Subaru
Model Forester
Year 2003
Engine size/type 2.5
Any mods no
Type of use (road/track) road
Additional info (max oil temps, current oil used)
What do you want a recommendation for? Engine, Gearbox etc?
I hope this will help and become a useful thread
Regards
Guy

Sorry for the delay, stopped getting notifications for some reason.
The Motul Gear 300 is ideal for the gearbox.
https://www.opieoils.co.uk/p-899-mot...-diff-oil.aspx
The best option for the diff is a synthetic 75w-90, like the Millers CRX NT LS, Motul Gear 300LS, Red Line 75w-90 GL5 or Gulf Competition LS. A SAE90 or 80w-90 mineral oil such as Motul 90PA, Fuchs Race Gear 90LS or Gulf Gear LS 80w-90 is a good, cheaper alternative.

Hi,
With the DCCD box, I would use the Motul Gear 300.

Yes, that's ideal.
If it's the 6 speed box, it takes 4.1L, or 3.5L for the 5 speed. The diff takes 800ml. If it's the 6 speed, you can get away with buying 4L and you'll have 200ml left over from the diff to make up the difference.
Cheers

High mileage modified WRX
Hi Oilman,
My WRX is now pushing 150k miles, and has been running 360 bhp for at 50k of those miles. (TD05-20G turbo and Andy Forest mods and tune).
Its used as a daily drive and gets full throttle in 2nd for a few times every journey (15mile to and from work). Have been using Millers nonotech 10W-40 or similar high quality oil and changing every 3k miles. Temps normally around 90C.
Its started imtermittently using oil (maybe sneaking past sealing rings while parked up) occasionally puff of white smoke on start up. So its going to need a rebuild soon.
Are their any oils better with high mileage (Mobil seemed to market some oils for high mileage)?
And should i stick with 10W-40 or change?
Thanks..

Hi
High mileage oils are pointless, they are basically just thicker oils with the additives that decent oils should have in them anyway.
It might be worth going for a 10w-50.
https://www.opieoils.co.uk/c-659-10w-50.aspx
They are all really good oils to pick from and any of them will be fine for it.
Cheers

Oil flush
Is it ok to use oil flushes prior to service? Are they ok with the turbo bearings etc? Ive bought a bugeye and the current oil is black as coal.

Hi,
Unless it's in a really bad state, I wouldn't as they can be too harsh. If you want to give it a really good clean, drop the oil out, replace it with some cheap 10w-40 oil and leave that in for a few days. That will give the detergents in the oil a chance to gently clean it, then drain that oil and replace with some decent stuff.
Cheers

Fiat Ducato oil?
Hi Oilman
I'll be ordering 10W-50 for my Impreza as per your recommendation, just wondered what you recommend for a Fiat Ducato 2.3 diesel 130bhp with 130k. Just converted to camper van and going on a big european tour this summer (so prolonged driving at ambient 35C)
