I was checking the oil SAE viscosity grade in the owners manual (p.34) which highlighted a range of oils depending on outside operating range with thinner viscosity the colder the temperature.
SAE 20W-50 between -10c and 50c
SAE 15W-50 between -20c and 40c
SAE15W-40 between -20c and 30c
So what brand / viscosity are you using in your Z1 ? The Opie oils site recommends synthetic 5W-40 for the Z1.
I am currently using Mobil Super 2000 10W-40 semi-synthetic in both the Z1 and the TVR. The Z1 uses no oil while the TVR settles at 75% showing on the dipstick range, top it up and 100 miles later its back to 75% where it will happily stay.

Oil - which one ?
Re: Oil - which one ?
I believe 5W40 full synthetic is recommended however I would not be surprised if you get a variety of answers. Changing the oil on a regular basis to avoid sludge build up is best and you can use a mineral oil on a temp basis to use as a cleaning agent. Be sure to change the 2 small 0 rings in the oil filter area. Drain oil when warm and don't over tighten the drain plug. Have fun.
Re: Oil - which one ?
I'm guessing your reply is directed towards the Z3? The Z1 doesn't have the 2 rubber O rings as it uses a spin-on filter - see http://bmwfans.info/parts-catalog/Z1/Eu ... il_filter/Cooper01 wrote:I believe 5W40 full synthetic is recommended however I would not be surprised if you get a variety of answers.

Sorry felix i should put on my glasses before replying to threads. Lol. I missed the z1 part.
Re: Oil - which one ?
Fuchs full synthetic from Opie oils and you get a oil filter 'with a O ring as well'
Re: Oil - which one ?
Hi J
I was thinking about engine oils rather than the gearbox, especially the modern thin synthetic oils for an engine designed 30 plus years ago. I am not too concerned with high mileage, longevity between oil changes given the low annual mileage, in fact the the car has averaged 1500 miles between services over 24k miles.

Re: Oil - which one ?
TJS,
I use Fuchs/Silkolene (depending on which day of the week it is and which brand they are pushing it seems) Pro S 5W40 in both the Z1 and the (older) CSL on Opie Oils' recommendation. I think it is a lovely oil and though the Z1 shows no particular preferences, the CSL definitely runs better with that oil than with any of my previous experiments (Castrol RS and Mobil 1 mainly).
The Pro R is a fully synthetic esther-based oil and I can't recommend it highly enough.
