Is Millers CFS 5W40 NT+ Magic?

Hi all!

Not posted here in a while as everything is going swimmingly with the VRS, touch wood.


Speaking of things doing well, my last oil change I used Millers CFS 5W40 NT+ that I got from Halfords for €81 (expensive but I wanted to give it ago).

And lo and behold, my oil consumption has more than halved.

I put in 4.3L of the stuff exactly 1000 miles ago, so 0.3L below full, and now here's what the dipstick looks like now:



If we're to assume the dipstick is 1L between min and max I'd estimate it's at 4.0L/4.6L, which would make my oil consumption just under 0.2L/1000km. This is incredible considering the fact it used to burn through 0.4-0.5L/1000km on Shell Helix Ultra 5W-40 meaning I'd have to keep a spare bottle in the car at all times.

Granted my current calculation isn't the most accurate as there could have been left over oil in the sump etc, but even with a pessimistic calculation of 0.3L/1000km that's still really impressive.

So is the fancy anti-friction technology that they talk about in-fact not a load of mumbo jumbo? And does this low oil consumption justify paying so much for oil?

Also I read another post on here where @Pudding said it was designed for racing and to be changed more frequently, is that something to actually worry about?

Thanks  :happy2:

I think the key is to stick to an oil the engine runs best on, and burns the least  :happy2:

Another important thing, irrespective of brand, is to change it more frequently than the manufacturer's service interval.  Chains, bearings, cam followers, seals and valve guide steams/seals will thank you for it in the long run.

Racing oils are designed to handle more sustained heat than manufacturer approved oils, but due to their chemical make up, often don't meet said approvals because every OEM oil now has to be low ash/SAPS to prevent DPF/OPF clogging, which most racing oils don't care about. 

As for the anti-friction stuff, tungsten disulphide is the most common one and definitely works.  Whether or not an engine benefits from it varies from car to car.  Nearly all OEMs say not to use oil additives, but at the end of the day, you can do what you want with a car that's out of warranty  :happy2:

I never tried the Millers but Castrol and Shell Helix are two oils that definitely burn off faster, and don't run as smooth.  Two oils that dropped consumption right down to almost nothing between 3-4k oil changes were Mobil 1 FS 0W40 and Quantum Platinum Plus 5W40.  The latter is especially cheap at £23ish from TPS, but they've recently dropped it, so get it whilst stocks last!

Anyway, the key message is to just change whatever oil you use more often.  I never felt good about paying 81 euros for Millers, so stuck to more frequent changes of cheaper stuff  :smiley:

I've had my car for about 7 years so have tried Shell Helix, Castol, Triple QX.  All of these needed regular top up - anywhere between 1 litre every 900 to 1500 miles.

Last oil change I used the Millers and my consumption more than halved.  So yes, Magic!

Coat me £39 for a bottle.
