what oil do u use in your e30?

[StuBeeDoo]

10/40 semi-synthetic.

[zaust]

Castrol classic (in the geen metal can) 20w/50. Always have and alway's will...

[bav]

i heard that using new synethitic oil which is thinner isn't actualy good for the e30's and the old thicker stuff is better, is this true?

[zaust]

Correct imo. There was no synethitic oil around when these engine's were designed, Also with wear the thicker stuff will keep your comp in the right place when hot.


I know many will disagree, but I have well over 300k on my bottom end I have alway's used the same oil. Just change it when it start's going dark...

[georgen]

10 / 40 Castrol GTX. Job's a good 'un...

BMW 10/40 semi-synthetic

[Morat]

10/40 semi. I burnt so much in my old E30 that I used Halfords, haven't had to replace/top up my current one yet.

[sam325is]

BMW use 0w on all enines, so im not sure if thick oil is such a good idea. However 0w will go straight through and old engine that hasnt seen a rebuild. I use 5W 40 silkolene as recommended by oil man.

The thinner the oil the more protection there is on start up surely

[maxfield]

I've got 20/50 in my M40. Needs changing really.

My dad uses 10/60.

[capri_rob]

Haven't changed the oil yet since I bought the car in February - its still fairly clean so don't see the point just yet. Always used Castrol stuff in the past.

[Fushion_Julz]

I use Silkolene oils...

In the 325 and 320 it is Pro S 10w40 in the M3 it is Pro R 15w50

[sideshowbob]

Just had my 325 convertible serviced, it has only 40k on the clock and only 3 owners. Garage informed me that it has always had Mobil 1 fully synthetic in it. I decided to carry on the tradition.......but expensive and worth it long time. My view on oil is the better the oil and the more frequent you change it the less problems you will have.

[csl]

I use Silkolene Pro -S 5w-40 in engine, Castrol SAF-XJ 75W-140 (LSD) in axle and Castrol SMX-S 75W-85 in the (manual) gearbox.

All the above have been used on the recommendations of various zoners and Oilman himself.

Same as that. Buy 3 get 4th free on trade club. On trade club it is only about £7 a tub as well.

The prices have gone up, inline with oil prices though. Bought 4x5l tubs of fully synthetic and it came to £60. The trade club prices have eventually gone up.

Does anyone know the original spec? Surely it must have been a mineral grade like 15/40?
