At the moment I use 10W60 Castrol RS (used in my 93wrx and now my 98 Type R not saying it's the best just what I use ),if you do a search you will find plenty of threads and opinions on your question

Either a 5w40 fully synthetic, 10w40 semi or fully synthetic or the 10w50 fully synthetic, a w60 isn't recommended, especially with winter coming up (it's not recommended at all really).

Me too. 10W60 here in cold Scottish winters.

I think the point he was trying to make is that make sure you oil is up to opera tine temp before heavy use.

My 10W60 takes around 5-1o mins of gentle driving to fully warm up compared to say a 10W40 that will warm up considerably quicker.

Ah right. Great info thanks, I'll stick to the 10/60 as I've got some left over from the last change.

Here we go....

My brothers mates dads uncles friend was using 10/50 and his car blew up so whatever you do don't use it.

LOL......

10/40, 10/50, 10/60 fully synthetic are all fine chap. I've used all three grades over the past year.
As long as you do regular oil changes with good quality oil and filters you won't have a problem.

Only thing with 10w60 is that makes the engine work harder due to being so thick causing power loss due to greater friction, hence 10w40/50 being the oil of choice. Hey its free power you really going to complain lol

Read your manual, did you find where a 10w60 was advised as being recommended by the manufacturer? You will find it's not and there is a reason for it, even those in cold winters won't get a w60 up to temp in 20 miles, it's too thick, hence you use a 40 or 50, a 60 is good in a heavily modified car as they produce more heat, but you also have a higher sheer value, it's not a good every day oil.

Are you a specialist in oils are you ?? Ive ran 2 scoobs and a 380 bhp evo on 10 / 60 in extreme conditions everyday cars no problems. Garage serviced our scoob before we bought it with 10 / 40 i changed soon as we got it as on cool down she was smoking on idle. Since putting the 10 / 60 in had no problems.

I guess many people are living on the edge of disaster then Tony, lol.
As from the few posts above you can see that people use a 60 and have not had any issues. I know I never have and many people I know never have.
I completely see your point about it being harder to get up to temp, but this is why I feel it's so important to have a oil temp gauge. As long as you get it up to temp then there is no problem. But as you say, my car is not quite in standard trim so this could help.
Don't get me wrong, I have used many different grades over the years. I'm currently using 10/40, but will be doing a service in the next couple of weeks and going back to 10/50. I find a 40 too thin causing alot more mechanical noise (could just be me hearing things though, lol).

Probably because the engine is fooked and a thick oil (slick 50 ) fills up the holes
Dont be fooled by thick oils, they are not that good for your engine!

Run a 5w40, probably see better temps and better oil pressure.

4 scoobs over 10 years, if your car is burning oil (you state your car smoked on a 10w40) then yes your engine is fooked
A 10w60 just masks a problem you have, go take it to an engine speciallist and get it diagnosed, probably stem seals.

I hear what your saying Tony regarding the 60 but on the other hand I really think 40 is too thin. Hence I'm going back to 10/50 in a couple of weeks.
Always seen good temps and pressure though on all the grades I've used.
I suppose it's each to their own, everybody has different opinions and experiences.
Could murder a strawberry milkshake now you've mentioned it though you bugger, lol.

A 40 isnt too thin, tbh its probably just perfect for everyday use, run on a track and yes hit a 50, though if you have a classic a 30 is too thin.
Ive ran all 4 of my scoobs on w40 weight oils, then one on a 50 weight, you could tell the difference in winter on the 50, more sluggish though as 40 is pretty much a standard oil for all cars its what subaru recommends, and you get more than plenty running 150k+ on the stuff

The thing is my car isn't used very often. For example this year it's done 2000 miles. Most of which was pretty hard driving. It comes out of the garage on a Sunday if it's dry and solely used for fun.
So for me I think a 50 is the better option. Car is slightly modified and currently at circa 400..
