1.because 1-2 and 2-3 were poor when cold and less than good when hot.
2. Despite having a full VWSA service history up to 2003, I was worried about how much oil was left inside.
The drain plug was a bit tight, but I used a tried and tested method. Apply only hand pressure to the jack and it works a treat:
Quite a decent quantity of dark bronze-coloured oil in the pan, and this on the plug:
Not too much fir but those two chunks are the tips of synchro-hub teeth
Could be worse, I guess.I refilled using the "oil enema" technique
2 foot of garden hose and a funnel. Magic. It got to 3.7 litres then started to drip, so I quickly jacket the offside of the van and got it up to 4 litres. Filling plug in sharpish and clear up. How much oil did I drain out? 3 litres - just.Went for a spin around the block, much better, even from cold. 1-2 still needs respect but it's done 120k of hard mileage in 15 years.
When I got back home, I emptied out the tools, oil barrel etc and noticed something. I looked again. £$^&*(@>!
GL4, but EP90! I was so chuffed with the price I got on 25litres I hadn't noticed...Well it's one side of 75-90 and it drives OK, so we'll see what it's like in the winter - if it hasn't come out by then for some attention and improvement of the "limited" variety.
There's enough for 5 more fills!
