I have been trying to get hold of the above oil for my up coming oil service but have been told by my usual suppiler that 15W50 is no longer available due to motul re-configuring all they oils, does anyone know of this and what type of motul oil is the one to replace the 15W50 300V competion oil? Cheers for your help Steve.

Len at Subaru4you has loads, think it's http://www.subaru4you.co.uk

absoloutely mis-informed i'm afraid........................

there was a change in the formualtion of ALL 300v grades at the beginning of the year however they still included the 15w50 (along with 0w40, 5w40, 10w40, 20w50, etc........)

this is probably our biggest seller out of the Motul range........................

Alyn is THE man for Motul. Ask him about his deals for 4 or more containers
May as well get some of that excellent Millars turbo CVL octane booster thrown in for the same carriage !

Drains your power that 15W-50 IMO .... wants the point of paying £2000 to get 20BHP more and then wiping all that out when you pour in treacle!

Subaru say 10W-40 and thats just fine and dandy by me - after all they spent £millions researching and building this engine .... and many units tested to destruction.

Pete

The above comments are for operation in the UK and normal everyday driving!!

yep Subaru test many units to destruction................normally customers ones without warranty!!!

[QUOTE=pslewis]- after all they spent £millions researching and building this engine .... {/QUOTE]


if only they spent a few more millions to figure out why so many lose big end bearings for no apparent reason

funny they also spent millions developing the engine's power output only to have a poxy small outfit like prodrive come along and respec it for them.

I agree with Alyn, Motul 300V 15w-50 is available. I've plenty too. Look in the Group buys threads.

now there's something we don't do every day..............LOL..............


alyn

oilman always thought you were against 15-50

Nope, in principle it's fine although not so good in the winter for cold starts. It's also not needed for most stock road cars.

If an sae 50 is required through mods/use etc I prefer 10w-50 for all year round use.

What I'm against (and it's well known here) is sae 60

Cheers
Simon

Don't be stoooopid ............... he's got stock to shift

JOKE!! Well, kinda'!!

Pete

15W-50 ................................... ok, if you live in the Sahara or blast the engine round a track in the summer ..

But, general use, in a standard car??? NO!!!!

Pete

Does living in Dubai count as the Sahara

Last track day (end of May) air temperature 48C, Motul 300V 15W50 running at approx 130C with a 16 row oil cooler.

Water temperature at 107C - larger radiator on order.

Oil normally runs at 115C, and thats just on the drive to work!

Now, that's hot!

Those temps will test most synthetic oils, petroleum oils don't have a chance in these conditions.

Cheers

DubaiNeil,

Have you tried removing the thermostat ?

The standard rad' is very good, but the thermostat is very restictive. I would try taking it out, and see how it works, before buying another rad'.

I would also look at where your oil cooler is positioned, and the air flow to it. If you can, make a shroud that directs the air through it.

Mark.

Mark,

Thanks for the reply. I haven't tried removing the thermostat, but will give it a shot. I'm worried that the FMIC as well as the radiator + aircon (which is kind of essential here!) is overloading the system a touch, hence the thought of a bigger rad. The supplier in the good old USA is giving me loads of hassle about the shipping, so I may well cancel the order and see how I go.
The oil cooler is in the gap behind the fog lamp - which has been removed The FMIC pipes run through that area, so I am planning to duct air 'at' the oil cooler, before trying a bigger one. I didn't want to put the cooler in front of the rad due to yet another cooler at the front of the car (IYSWIM).

Normal water temp is about 94C (according to the SECS), but can increase to 100 in 'enthusiastic' use.

I'm planning a TD05/6 etc and wanted to get the heat management under control before causing myself more problems!
