engine oil

[rs phil]

running 10-40 magnatec at the moment was recomended by jzm,any one else running this oil for track days? was thinking of running 15-50 mobil 1 motorsport???whats best out there

I use silkolene pro r race oil 15/40.Its one of the best and has more of the metal clinging agent/polymers than the magnatec and mobil.
Its also as cheap if you can get a account with Fuchs oils who supply silkolene by the 20ltr containers.
It pays off when the engine needs a rebuild as the components are in much better condition.

I also used this in a GT3, but couldn't get the OPC to confirm that it was Porsche authorised. I don't know why ---

But the high Esther polar molecules seemed to make a lot of sense !

I use the Silkolene in my C4 as well (mainly track mileage)

Few people use in the RS's as well.

Cost about £30 per 5 ltr from Oilman (forum login) Opie Oils

Easy one, this ... Porsche approve no oils with a cold viscosity (the W rating) greater than 5 - this has been the case for some time now. They must have their reasons (they do an awful lot of testing) but I am not privy to them ... the millions of deluded but happy M1 Motorsport 15W-50 users do not seem to colour their judgement one jot !!

HTH, cheers, Maurice [8D]

Hi - I think this was referring to the usage of Silkolene Maurice, as it's not on the Porsche approved list (although it is on my approved list and in my car)

Either one fits the bill, Pete, they are both > 5W viscosity, one is not even synthetic !

True - I use the 5/40 Silkolene Pro S - Don't understand this obsession Indies seem to have with Magnatec

thanks lads,would 10-50 s silkolene be better than 5 -40

 

[rs phil]

The 10 will not make any difference on a track, as that is the cold viscocity, so I would stick with a 5 weight.unless you live somewhere really cold [] as that will give you better cold start protection.

50 also sounds a bit thick - any specific reason for wanting something that thick

Current Porsche approved list is here :http://www.porscheclubgbforum.com/tm.asp?m=230743 - no 50 W on there []

What is the temp / pressure like when you are on the track?

I think the main thing is to use a fully synthetic oil for the shear resistance and change it regularly if you are on the track a lot - 100 track miles approximates to 1000 road miles allegedly.

[rs phil]

oil temp and pressure are fine no probs there,just a bit worried about the magnatec as it so cheap? when all mobil and castrol tws which i use to run on my m3 s were alot more expensive,5 - 40 it is so,thanks also what gearbox oil do you run ? i am running,saf-xj castrol ,limo works great with it but the noise of gear clashing is very noisy,porsche recomend something else but the limo is not supposed to work aswell..just what i was told?

 

[964rh]

Using the silkolene gearbox oil as well.

I'll dig the name and type out later

 

[rs phil]

thanks lads ordered 10-50 silkolene and silkolene 75w90 s gear oil silkolene too,went for 10-50 as i think it is better for track use

 

[rs phil]

also got it from guy at opie oils,very helpfull

 

[964rh]

Gearbox oil stinks, even when new. Be careful when your filling not to get on your clothes if you want to wear them again!!

I used a big syringe to inject into the gearbox, in the absense of a lift it proved really helpful.

I still stank tho' [][]

 

[Ian964]

A popular choice is Mobil 1 Motorsport 15W-50 - fully synthetic but slightly more viscous than the 0W and 5W grades.

 

[Markit66]

Thanks for that Ian.

Had not noticed this oil before,will look into it.

I think the advice you got suggesting 15/40 semi-synthetic is spot on. I use that grade of oil in my cars, and my preference is Castrol Magnatec

Mark, my car has had Mobil 1 Motorsport 15W-50 for donkeys years but for the last couple of oil changes it's had Castrol RS Edge 0W-40. Never had any engine problems but then again the oil gets changed every 2000 miles! Don't think it makes that much difference what you use as long as it's changed regularly. Saying that, maybe it does if you plan on doing loads of track days.

10-60 edge sport,have been using it for years most specialists recommend it

 

[kasbridge]

Shell Helix Ultra 5W-40, no leaks and approved by Porsche and as used by OPCs in Germany for 964RS I am told by Thomas...
