I was wondering if anyone had come across Smith & Allan of Darlington. Family firm since 1925 specialising in blending lubricants, etc., and an official Shell agent.
I used their LL04 equivalent Momentum C3 5W-30 in my E46 330i (150k) without any problems. Price for 5 litres in April this year was £19.02 including £8.34 of UPS 20kg rate.
I'm checking my B3 ZF 5HP19 fluid level this weekend - no leaks as far as I can see - but it's dropping from 5th to 4th at exactly the same point going up this long incline near me (even at 70mph) when I don't think it needs to so I've ordered 1 litre of S&E's LA2634 Lifeguard 5 ZF synthetic ATF. Price £9.99 inc Royal Mail parcel post. It is equivalent to ZF S671 060 170 and BMW 8322 9407765 / 8322 9407807. They stress equivalent rather than just compatible which are not necessarily the same. I'll let you know how it goes but I need to find a bendy thermometer first. Now there's a specialist tool I never thought I'd need.
