Wanting to do an Oil change on my 06 Impreza.........Whats the best oil to use.

Only had the car a week, the garage said they did a full service but I don`t trust them.

pslewis

What do Subaru say in the cars Handbook??

il quote from the handbook pete

"when frequenting forums desegnated to our fantastic brand, we advise on one major point. this point is to ignore and disregard anything that MR PSLEWIS may have to say, with respect to oil changes, servicing, and maintaining of the subaru brand"

my japanese isnt really upto scratch but it was a brief translation

pslewis

Disregard pslewis and disregard Subaru themselves ............

if only others agreed with you, your claim would have substance, but....

pslewis

Now it's all relative, see??

I would suspect that 98% of Subaru Owners do NOT come on SN - and I would like to wager that they all use the Oil Subaru say in their handbooks (and therefore what I say).

So, you seem to be speaking with forked tongue

To answer the original question....

Subaru recommend 5W/30 or 5W/40 synthetic. I would buy a known brand despite what Pete says, as I think my car's worth spending an extra tenner a year on its lifeblood. You don't need to go mad with racing spec stuff, but brands like Millers are highly regarded and don't cost the earth. Silkolene are often recommended, but Castrol Magnatec isn't.

One odd thing as my local dealer uses fully synthetic oil, which isn't specified in the handbook. Hmmmm.....

pslewis

COMMA is well known and respected by those who know whats what.

AND, the viscosity depends upon driving conditions and temperature ranges, I think Subaru actually recommend 10W-40 SEMI.

I would simply stick with what the maker of your car states, they built the thing, designed the thing and have tested the thing.

pslewis

Deerrrrrrrrrrrrrr and that will be HOW MUCH??? I think they tell you thats what they use to empty your wallet

andythejock01wrx

LOL - you're as trusting as I am ! (I get any car i buy serviced as soon as i buy it, regardless of the stamps in the book !).

Mark'sWRX

Pete, the manual for your Classic may state 10W/40 semi, but my Newage states "5W/30 is preferred". Fully or semi synth is not stated, but "Energy conserving SL or SJ" is. A higher grade is only recommended in hot weather.

Yes, I was sad enough to fish out my owners manual!

andythejock01wrx

Worst case scenario - fully synthetic is unnecessary and you spend a few quid more each year.

Or should I say, "Worst case scenario - it is necessary and your engine doesn't last as long".

andythejock01wrx

So, a couple of options :

Comma semi synth as per Pete.

Silkolene Pro S 5w40 ester based fully synthetic.

pslewis

And I would bet that my engine lasts longer than yours does without needing work

considering he has modifactions, and you seem to only realise the first two gears pete, id wager with you on that one.

but i hazard a guess you will be crashed into first, when your 66000 mile brake pads fail you...

pslewis

The Rear Brake Pads are now on 81,000miles

dpb

Pete still tryin to flog the comma tosh i see

pslewis

Nowt wrong with COMMA Oils ..........

Top Quality at a proper price

Like I said, for those that know -

.... the others can go and get shafted with their 'Slikolene Rally Xtra Protection Triple Action Ester Polymide Fully Synthetic Sports Turbo API BS Spec Ultra Super-Duper' only £40 for 4 Litres!

andythejock01wrx

5 Litres. C'mon Pete, it's not like you to get your facts wrong !

How is it you calculate your fuel consumption BTW ?

pslewis

I thought the expensive Oils were sold in 4 Litre Cartons??

That way they make you pay £9:99 for the other Litre you need?

andythejock01wrx

That's true of Mobil 1. Most irritating (if you buy the stuff).

Comma semi synth is to API SL and matches the Subaru requirements (it being strictly not relevant if its full or semi-synth - the requirements are the requirements).

Comma (Welcome to the Comma Oil & Chemicals Ltd. Website) also markets Mobil1 in the UK.

Mobil1 is however API SM, and personally I would use it.
