so does it make a difference if you go from using fully synthetic to semi? 10w60 is more for older engines from what i have read. I might just switch to the Castrol magnetec 10w40 semi or the Mobil 1 Super 2000 X1 which is actually fully synthetic
Wont make a difference if you wash through a half litre or so after a full drain...basic rule of thumb is fully synth has higher tolerance to heat, will last longer.
Maybe the Mobil 1 Super 2000 X1 will do the job so, 10w40 and fully synthetic, im wondering of it offers the same cold start protection as the Castrol magnetec. i doubt ill be bashing the car too much on the track day anyway!
Local tractor parts place down here has 15w50 mobil 1 unbelieveably enough-and hasn't sold even one can of it in 6 months-prob cos he wants €72 for it and mine is the only subaru around here

it wont on initial start up but fully snyth does operate better in cold as well as hot..I wouldn't have anything but the best oil in for a track day...you can still us it on the road then after for a 1500kms or so then when it gets colder switch to a thinner oil
So doing some more digging and looks like Millers 10w50 and Fuchs 10w50 are a popular choice, great cold and hot temperature protection. I have never seen the Silkolene/Fuchs for sale anywhere but will recheck for this grade in southside motor factors as i saw they sell Millers there, knowing my luck they wont have it either! Anyone know anywhere else that stocks the Millers?
ye its seems like most places only sell 5w30 or 10w40 blends, and look at you like you have two heads if you ask for anything else. "sure what you you need that for"!
ye like whats that never heard of that but ill check,have to order it but.not like uk, a bit like our petrol,, last in europe to have anything we need still charge us s..t prices for crap
ive always used silkolene race pro r in my scoobys 15w50... id never go lighter.. even in normal driving in winter the oil gets to a serious tempreture..
