Impreza STi Engine Oil Change
Discussion
Silkolene Titan S is recommended for Evo's so I'd imagine it would be good enough for Subaru's too! Use the weight specified by the manufacturer.

10w50 for modified Impreza instead of the usual 10W60 that's been heavily recommended the last few years.
I've used 10W60 and found my car generally ran better with 10W50. Might be all in my head but that's my experience. There are time attack Impreza running 10W50 and doing very well on it.
If i put my car back on the road i would probably now opt for 5W50. We've had some very cold winters recently into the -double figures so i think an oil starting with a 5W would be my preference. There's 5W40 as well if you don't drive the car hard too often. Covers a wide spectrum of operating temps.

5w40 is the Evo standard oil.
10w60 is run by some people with modified cars. I believe their rationale is that the oil gets above the 'normal' temperature, and at those extremes the thinner w40 oil will be too thin but the w60 'about right'. However the converse of this is that when the oil is cool (i.e. being driven 'normally' not on a track or on a mission!) the w60 will be too thick but the w40 would be about right.
If my oil temperatures were so high that w40 would be too thin then I would improve the efficiency of my oil cooling system (ducting or bigger cooler, or more rows) rather than just put thicker oil in.

Thanks... Oddly, the Shell web site recons 5W30 for an STi (you enter your number plate).
What does the manufacturer recommend in terms of weight? The cars handbook will be much more reliable than a system based on your reg. (Because the reg will tie up to a model held on the DVLA computer, which isn't always completely correct, especially with respect to Japanese/Import cars.)mrmr96 said:

I checked and its currently running 'Silkolene Fully Synthetic Pro S 10/50' ...
"Pro S" has been rebranded to "Titan S" by Silkolene in the last year or so. It's exactly the same stuff though.Subaru used to recommend 5W30 Semi Synthetic for all newage Subaru. Spring/Summer 2009 they changed their minds and decided 10W40 fully synthetic should be used as per hatchbacks.
In the interests of the environment and to meet EuroVIII emissions directives a couple of years from now, i've no doubt Subaru will be recommending you use extra virgin olive oil made from olives pressed between the ar5e cheeks of teenage vestal virgins while sipping camomile tea from the backs of golden cherubs!!
Failing that, chip fat might do

Which ironically will probably be cheaper 
50 quid for 5ltrs!Edited by paulmoonraker on Tuesday 12th July 13:07
