i have only ever used Millers oil but iv had so many different answers about the grade of oil i should use when i do my oil change. i have a 2004 wrx runnig 340 bhp.
the differnt types i have been told are:

10w40
10w50
10w60
5w30

so i thought i would as the experts
which one would be the best ???

 

I tried 5w40 cfs and my car rattled so i drained it and went to 10w50 and that is much better.
I think i read somewhere that most blown engines that API see have been run on a 5w
I run a standard 53 wrx that is garaged so is unlikely to see really cold temps.

 

just bought some 10-40 millers cfs, red an old post and a top mapper on here use nothing else.

 

top man! cheers

 

Another vote for the 10-40, just done an oil change and everything is perfect.

 

Jus had uprated oil pump and oil coller fitted and they put millers 10-60 in.

 

I asked the question once to the Oilman at Opie Oils. His answer was 10-60 for a newage and 10-50 for a classic. That was for Silkolene Pro S though, but should be the same for Millers.

 

We would have said 5w-40 or 10w-50, not 10w-60 as we usually advise against that.

Always been curious as to how an engine 'blows' using a 5w

I always use millers cfs 10-60

I have never had any problems while using it and I track my car every month so it gets a bit of abuse

 

Zen built 2.0 and they use 10w-60 in mine....????

 

I don't know exactly what they did to the car, but tuners often think that any car needs a 10w-60 when it has been modified, but can't give a real explanation when you ask why

 

My apologies, looks like I remembered the newage wrong (I've got a 1995 classic, thats the bit I remembered correctly). Knew it was a grade different, 50/50 and I got it wrong

 

I've been using 5-40 Millers quite a while now and change it every 3k-4k miles.

Is this oil not reccommended?

 

No reason why you cannot use it.
