OK, I've read about a million articles on here about Oil and which one to use - I should have probably quit after the first one and saved myself a hell of a lot of confusion!

My car 2002 Sti PPP no other mods - what is the best oil to use? I'm not that fussed about price but don't want to spend an absolute fortune 'for the sake of it'.

Hopefully it won't turn into the full on war that is the PS Lewis Oil change thread

Do as SUBARU recommend ........... you cannot get better advice than that!!

I have no idea what the SUBARU stance is on Oil for your particular vehicle, but any main dealer will know ..... so, I will not comment on this one

Subaru recommends a semi synthetic oil for my year 2000 turbo, in the end I got 5 litres of Valvoline fully synthetic for £25.

There really is no need to pay any more than that

remfanuk

why do subaru recommend semi synth and almost everyone goes and gets fully synth?...i also have a 2000 classic and will be sticking mobil 1 in mine.

i cant see the point in your reply to be honest m8.
subaru say one thing and youv'e done the other.
stick to what your manual say's and you wont go far wrong.

For new age cars they say use a semi, so thats what ive done .

Is this quick enough.

5w-40 fully synthetic.

================================================== ==============


Subaru do not recommend semi-synthetic, they are protecting owners from putting too lower grade oil in the car by giving a minimum requirement of semi-synthetic!

I have spoken to Subaru my self about this and posted details of the conversation here some time ago.

They actually recommend 0w-40 or 5w-40 for all cars after 2000 as the best option.

Mr Lewis is not wrong, a 10w-40 semi-synthetic is permissable but it's not the top option, it's a minimum requirement - They are two different things!

As for what should be used, read your hand book, in post 2000 cars it lists viscosities, not specifying the quality, if it mentions either 0w or 5w oils, theses ARE synthetics as semi-synthetic oils ARE NEVER 0w or 5w as they cannot be made as such without using synthetic basestocks.

Please read this carefully and then make your own mind up, Mr Lewis excluded as he has already made his mind up.

If you think synthetics are a waste of money then I'll post the reasons why they are not but at the end of the day it's personal choice.

Thats an opinion ...... it shouldn't be posted as a fact, it's entirely subjective whether something is a waste of money!

What you have said other than that is fine

Pete, I'm not going to post an opinion, you should know me by now. I will post the facts so that people can make their own minds up.

How can people make decisions when they don't know the facts? I was merely offering to post the facts

You'll be an oilman one day pete

Cheers

pslewis

You said that you would explain why Fully Sythetics are not a waste of money ...... thats an opinion!!

If they cost £1million a litre I guess you would agree they WERE in fact a waste of money .............. at 5p a litre I would concede that they are NOT a waste of money.

It's subjective see??

One day you will truly understand what is an opinion and what isn't

Pete,

If that's your opinion, I still don't understand it

I was going to post the "technical reasons" that they are better. NOT opinion.

Here's my opinion - You're mad as a march hare

Cheers
Simon

pslewis

I'll try and explain ........

You said, "Fully Synthetic is NOT a waste of money" ..... thats is subjective.

Why, well simply put like this:-

You would agree, and I would concur, that at 5p a litre Fully Synthetic is NOT a waste of money (as Semi-Synthetic at its current price of £3 a litre is more expensive)

BUT, if that same Fully Synthetic is £180 a litre (the same ratio, reversed) and the Semi is still £3 a litre , then, I am SURE you would agree that in that case the Fully Sythetic IS a waste of money!!

Therefore, it is purely the price point at which the Fully Synthetic is set that dictates whether its a waste of money or not ................. and that price point is different for every man, woman and child in the country.

That explains why your statement, "Fully Synthetic is NOT a waste of money" is an opinion and NOT fact!!

Its subjective ............

Get it yet???

Subaru do not recomend a 0W oil Simon, they recomend 5W as the minimum cold weight spec.


The oil you use should match your driving style, dont use the 5W-30 base recomended oil if you do sustained high speed running.

you best edit your post where you say Subaru recomend a 0W oil Simon.

oilman

iTrader: (9)

In some of the post 2002 models 0w is listed.

I don't personally recommend using anything lower than 5w but it's there and Motul, Castrol, Silkolene etc list 0w as well as 5w.

The reasons that I don't feel recommending it necessary is because most of us don't live in the arctic however it gives better protection from wear than 5w.

Cheers
Simon

johnfelstead

care to show me which models Simon?

Bob Rawle

Agree with John Subaru do not recommend a 0-40, they also recommend NOT using 5-30 or 5-40 if "heavy" use is undertaken (and thats also in the manual)

cheers

Bob and John,

Once again I'm not disagreeing with you and each car depending on use, state of tune etc should be taken on it's merits and particular requirements.

Here is my original post:

http://bbs.scoobynet.co.uk/showthread.php?t=378713

Interestingly enough I checked with Castrol last night and they list 5w-30 for all models post 2000 which has changed from 6 months ago when it was 10w-40!
This seems rather broad brush in my opinion and somewhat irresponsible should anyone having more than a stock car used on the road check their site for recommendations as 5w-30 would not be my recommendation for a tuned or track car.

As I have said before when you look at the history of the Impreza model wise, related to a basket of recommendations they have definately changed as newer models have come onto the market from sae 50's to sae 40's to sae 30's in relation to standard road cars which is not out of step with the car market general as most OEM's seem to be changing direction with regards to recommended viscosities as oil technology and I guess engine technology is progressing.

Who would have thought 20 years ago that some OEM's would specify only 0w-30 oils for their cars otherwise warranties are voided! We live in changing times.

Cheers
Simon
