which oil?

[squeal]

which oil is best to use in a 318is and a 320i,ive been advised magnatec for both-is this correct?

[Demlotcrew]

you can use castrol 10w40 if you wish and if you dont drive the car hard and dont want the extra expence of full synth then yeah go for that.

But i would use 5w40 Silkoline or for full protection use Motul.

I use Mobil 1 0W-40 (after quite a lot of thinking !) and its going like cream at the mo

is the magnatec a myth mate?dnt really mind the cost difference as long as it runs sweet as it can

[Demlotcrew]

Jose 0w is too thin when cold.

Castrol is not very good, it just cant handle the hight temps and breaksdown or burns too fast.

I would never use it unless it was for a car thats just used as a run around and doesnt need the protection of a full synth oil.

[squeal]

how much we talkn for a good fully synthetic oil

[JOSEMI]

I thought that was the idea, the thiner the better when cold, so that there is protection all the way round

Jose

[Demlotcrew]

your looking at around Ԛ£36 for a good fully synth

0w is too thin for the uk climate,

You might be getting all the condesation in the engine mixing with the oil, i had that once (not on my S14) but it will evaporate over time. Give it a few more weeks see how you get on.

0w is not too thin when cold, it's still 40 times thicker than it is at 100degC!

A decent 5w-40 is perfect for UK climate.

Magnatec, spiced up mineral oil, use a proper synthetic, much better!

phoned euro today n they said 10 40 semi synthetic is what my car is matched apparently

[oilman]

That's the cheap option, not the quality one. 5w-40 this time of year and synthetic too is the best option with winter upon us.
