Morning all,

Excuse me for what may be my stupidity but which engine oil should I be using?

I have an 06 STI UK with Prodrive upgrade.

Thanks in advance.

I use Silkolene PRO S 5w-40 in a 05 STI-PPP 2.5 may be different, phone the Oilman good advice IMO

As it's a MY06 I'm guessing you are just looking to top up, in which case stick with whats in there (I think the dealers use Shell helix of some type, call and ask them).

If you're doing a complete oil change then as above speak to oilman:
Opie Oils

pslewis

Another one to the sword ......... LOOK IN THE HANDBOOK!!

OR speak to Subaru - they don't sell oil so have no need to oversell you expensive stuff because thats where the fattest profits are for sellers of oil.

I can't resist, can I??

LOL Pete, thought you'd gone AWOL for a minute there !

Subaru Book suggests Semi synthetic IIRC, I use Motul FULLY SYN.

Snazy

Its a tough one but for standard cars I would be inclined to go with the manufacturer. After all they are the ones who have to fix it if the oil is rubbish and breaks the engine. So with their warranty claims in the balance, surely its in their interest not to recommend something sub standard.

However thats not to say there are not better options out there. But it also does not mean their standard recommendation is rubbish.

pslewis

Well said Snazy ............. but, no-one has yet come up with a definition of the word 'better' when applied to the logic of expensive oil versus oil that Subaru recommend.

If the oil is changed every 6 months I simply cannot see any benefit whatsoever with the expensive oils ..... if the oil is left in the engine for 2 years then I could see the logic for buying the expensive oil for its extended life properties.

It boils down to a 'feeling' ..... if you 'feel' happier paying £40 for 5 litres then there we are - do it. Personally, I like paying £12:99 for what Subaru recommend

RonnieB

It currently has 10w/50.

I presume this is fully synthetic as the oil change was done at TSL when I had some work done

Snazy

I got castrol in mine or something, from the dealer service.

a_fisher

Phone TSL and ask them what they used. I'd guess its Silkoline fully synth 10W/50

motul 15-40 fully syn

My Spec D with PPP has recently had it's 10k service and they used Castrol 10W-60 fully synthetic having given me the option to go for semi or fully synthetic.

I'm not too sure why they chose 10W-60 as this option is not in the manual. A response from Oilman suggests this is not an ideal choice so not sure about the next change.

See the following for Oilman's response https://www.scoobynet.com/general-te...ml#post7244341

The Castrol 10-60 stuff is not a proper fully syn. So many different opinions on many sites about oil. Either speak to Alyn @ AS Performance or Oilman to see what they suggest for your car/budget.

pslewis

10W-60????????

Good god that must be like treacle

Good for a 300,000mile 20 year old Sierra I would imagine - not so good for a Japanese Sewing Machine Engine ..... unless under extreme conditions in the desert!

maybe you should ring them up pete, and offer your advice and/or oil changing proceedures? just dont tell them youve been banned on here a few times for your indecsrections

pmarch bugeye

what about this comma fully synthetic 10/30 - with free HV vest?

pslewis

This is what I am currently using in my vehicles:-

The Oil Man - Fuchs Titan XTR 10w/40 Oil 5 litres (Powered by CubeCart)

You will see that The Oilman wants to take £23:99 off you - I buy it for £12:99!!

Quoting The Oilman:- "TITAN XTR 10W/40 offers outstanding performance and durability in today’s high performance engines, both naturally aspirated and turbocharged"

TSL use Morris oils (they produce a 10/50) - Bet you've never heard of them?

Abdabz

If you drive normally and service your car regularly you will never have to buy your own oil unless your car has a problem. I have only been driving 16 years so my experience is limited, but in my experience this is the case.
HTH

pslewis

I'm not sure what you are saying - is it that if it's Serviced by someone else, you don't have to worry about what is put in?

doppelganger

end of season sale?whats all that about does oil go off or something.

and i use what my mates at prodrive recommend ,halfords 10/40 with 3k oil changes

dpb

Id be amazed if Pete hasnt done the test already ..!

nigel s

Motul 300v 10/50 from Oilman

pslewis

Oilman is ALWAYS having an end of season sale!!!!

It's a marketing ploy - good luck to him ---- anyone who can find buyers for an Oil at £24 which I can buy RETAIL at £13 deserves riches beyond their wildest dreams ....................... just I'm not your average joe
