I have a 83k sti engine I'm about to oil change. Subaru recomend semi synthetic but I was thinking Castrol GTX high milage oil.
Any clues as to what would be best~???

 

irrespective of mileage i use Motul 300V 15w50 I wont use anything else

 

agree with above post

 

Prolong Super Lubricants, Inc.® - THE ULTIMATE IN PROTECTION & PERFORMANCE®

 

Is this the one?

 

thats the one

 

Another quickie, is it a 4.5 litre capacity sump?

 

certainly is

 

How much of it do I need? And it's ok for my 83k engine??

 

Sorry I missed your reply to the capacity before I posted

 

OK got 6 litres of the stuff deliverded @ £55.
Now for a filter......

 

Its 4ltrs in the engine and .5ltr in the oil filter
At that mileage if the car has never been run on fully synth, waste of money

Tony

 

that's the stuff.

 

It's been run on semi for the last 5 years so should be ok?

Cheers Stu..

 

There is no problem running a fully synth oil but with the mileage the wear is already there that the fully synth would protect against, hence your best just running the car on the same semi synth oil as the fully synthetic isnt giving you the start up protection because its already worn so your just throwing money away.

Tony

PS, you dont need a high mileage oil on these cars, high mileage on a modern car is 150-200k now

 

Use an engine flush to get rid off all the old oil and any deposits.

I have always used a fully synth oil. The car now has 80k.

 

Well I bought the bloody stuff now!

 

saw this post discussing engine flush - makes a good read.

apologies from a GTR forum

You're fine mate, use it, I do !

 

I've not heard of this stuff, is it really the best to use?

I've always been told Millers 10w60 or Silkolene Pro S

I need to order oil, so if this stuffs the best, point me in the right direction!

 

Going to Stu. Is that the Wagon you use it in or both?

He has 7 left and charged me £10 for delivery of 3 £55 for 6 litres is very cheap if you look at the price of it elsewhere.

Also look at this..

Engine flush = not good in a flat 4 engine, just stick to regular oil changes

Tony

 

It's certainly not expensive mate. Not in the scheme of things !

15-50 300v Motul in the Wagon
10-40 300v Motul in the Spec D

 

Why the difference in which you use between the 2 cars?

I use the same in both of mine (newage wrx and classic wagon).

Just curious

 

hi guys just brougth my 2000MY scooby classic a few weeks ago. ive just realised she needs more oil what the best thing to do drain all the old as i dont know what it is. and refil with new and get another oil filter(which i cannot find under the hood).

oh and just thought id share this ive just been a C***T and reveresed my darling into my own fu*****N garage door post grrrrr what a crap week got swine flu and tonsilitus too.

Rant over and any help appreciated cheers guys.

 

Go for a decent oil, not Castrol GTX Mineral Oil.

Use a 5w-40 synthetic if that car is for road use.

5w-40, 5w-40 oil, 5w40, 5w/40

Cheers
Guy
