I would like to get my JDM '94 WRX serviced fairly soon, but when i search threads on here there seems to be several different points of view regarding oil. I know mine has been kept on Mobil 1 but not which grade has been used. What should i be using? What does it say in the handbook?

Thanks in advance...

 

Some light reading for you, which hopefully will enable you to make up your own mind. As you say, there are many different opinions on this subject...

which is probably why everyone is avoiding this thread like the plague

As far as I'm concerned, the definitive answers are here (although others may disagree)

Well, I've got recommendations from three seperate companies who are all experts in oil.

1. Silkolene Technical Department
2. Motul Technical Department
3. OATS - The largest proprietory oil recommendation database in the UK.

And, these were the recommendations that I recieved from them:

Impreza 2.0i Sport 1996-00

Motul 5w-40 or 10w-40
Silkolene 5w-40 or 10w-40
OATS 10w-40

Impreza 2.5i 4WD 2001 onwards

Motul 5w-30 or 5w-40
Silkolene 5w-40
OATS 5w-30 or 5w-40

Impreza 2.0i WRX/STi Turbo 2001 onwards

Motul 5w-30 or 5w-40
Silkolene 5w-40
OATS 5w-30 or 5w-40

Impreza 2.0i Turbo 1994-00

Motul 5w-40 or 10w-40
Silkolene 5w-40
OATS 10w-40

Impreza 2.0 4WD 2000 onwards

Motul 0w-30, 0w-40, 5w-30 or 5w-40
Silkolene 5w-30 or 5w-40
OATS 5w-30 or 5w-40

Impreza 1.6i, 1.8i 4WD 1993-96

Motul 5w-40 or 10w-40
Silkolene 10w-40
OATS 10w-40

I also spoke to Subaru UK's technical helpline this week and they recommend a MINIMUM quality of 10w-40 semi-synthetic but also recommend 5w-40 fully synthetic and 10w-40 fully synthetic as higher quality options.

I asked about the use of 10w-60 and the answer was pretty much as I expected, it's not listed and therefore recommended. The nice gentleman that I spoke to was reading from the book though as he could not explain why this is the case.

Flame proof jacket on - makes a speedy exit!

The old threads are the best threads.

 

maybe their list needs updating...

 

Thanks for the replies Guys but they don't answer the question. The list of oils used does not mention a '94 JDM WRX. What do people use in their WRX's and what does the handbook say?


Thanks

 

I would use 10w-40 semi or fully synthetic.

Semi = Cost option
Fully = Best protection

Cheers
Simon

 

Thanks for that, i'll give it a try.
