Scottoiler E System Electronic Chain Oiler From  £269.99

My e-system v2 worked for about 8000 miles.
Really disappointed to be honest. The wires broke and frayed where they come out of the pump.

I contacted scottoiler and after several emails, telling me the warranty was up, me being miffed that although it's a few years old, it's not even lasted 8000 miles and not 100% sure the pump is the cause. They agreed to look at it and test it.

They've tested it and confirmed that it's actually the display (control until, that's faulty and can't be repaired, although the wires that broke on the pump is not going to last either.

Anyhow been offered the choice of having faulty unit returned, or can buy the new v3 (ha, I don't think so)

The v2 control was much better and simple.
The v3 doesn't auto calibrate, you have to guess we they it's matched right to your engine, it doesn't display the number of 'drops per seconds' as a number, it has lots of bars you need guess how many bars equate to number of seconds. The oil fill level is now in fifths instead of quarters.

Anyhow, regardless, It may make the chain last longer and auto oil it, but at nearly £300, and only lasting approx 8000 miles. It's cheaper to just put the cash towards a new chain sooner. I definitely can't recommend scottoiler at this moment in time.
