I am no expert as you know but,

I would say 10/40 or 10/50.

Better still give Alyn a call he will tell you everything you want to know,

and be able to supply what you decide on at a very competitive price.

i used 5/60

10/60 for me

10/4 good buddy

not sure of your spec of car but 5w oil isn't for a classic IMO.......

I'm onto 15w 50 at the moment. Does the trick for me

i'm almost standard running at about 300/310bhp. judging by my oil pressure gauge, 5w seems to be ok for me. if I get in and just drive 30mph from cold around town, oil pressure stays a little on the high side but the moment I get on to the A12 on my way to work (50mph) the oil pressure drops to normal on idle.

I thought 5w just meant the oil was thinner cold than 10w and therefore easier on the engine on cold start, especialy in winter

I,ve be on 10/60 or 10/50 for eight years .

I'm 10/50 but will be going 10/60 at my next change. Doesn't really get cold enough in the UK to warrant 5.

Thanks Guys. Will stick with 10/60 I think.

i started with the 5w40 first then changed to the 10w60, engine sounds better now so sticking with that.

10w60 is really quite a thick oil, unless your tracking /thrashing the $h1T out of your car, 10w50 or 15w50 for summers etc.(classic/newage sti - some mods)

I would use 10w60 on a built (400+ bhp engine)

Used Motul 300v comp 15W50 for a long time and had no oil issues and really wouldnt run anything else in a subaru engine.

Although the 10W60 millers a couple of customers use also seems good, having monitored oil temp and pressure on the ecu on track.

Thanks again Guys. Power is 323bhp/330lbft so not up there with the Dudes on here.
