oil question

[aceifty]

my 325i cab is due a oil service, iv used Castrol Magnatec 10w40 in the past. this time id like to you something better can you guys recommend some to me plz.
the car is slightly modified, it has a straight full stainless steel exhaust from manifold to back box (no silencer) plus a C2 alpina chip which made the car very Torquay.

also at times the car is used hard.

There is some advice about Oils 'stickied' in the Technical Help section.

Basically, any 10W40 semi synth is more than adequate for road use. Better to spend money on regular changes than whizz-bang carlos fandango oil IMO.

ive been using castrol magnatec 10w40 fully synthetic.
thinking of using the same or 10w40 fully syntehtic from silkolene or there 10w50 fully synthetic, which would be best for me.

Read the oilman stickies in tech help.
