If you are going to create a Poll, please ensure that the questions you ask are concise, not mutually exclusive and will give the information you want.
The current poll asks members to choose between 'this oil is fine' and 'I wouldn't fry chips in it'.
Personally, I have never used it so can't tick the first box.
However, I wouldn't eat chips cooked in it because they would taste dreadful. And I never fry chips! I could tick this choice but it won't tell you anything meaningful about my choice of oil for my K.
So, I don't vote.
Perhaps a more meaningful choice would be to ask members whether they would you use non-BMW Advantec oil in their K...
O Yes
O No
Simples!
It always amazes me that folks buy a fairly expensive, relatively high tech, 170bhp, 170mph motorcycle and then want to save a few quid on things like coolant and engine oil.
If you can buy oil at £10 /litre less than Advantec, this will save you £0.58p per mile or a couple of tanks of fuel, on 6,000 mile oil changes.
You could buy cheap tyres and save more than that! Or run regular unleaded!
Oh, the perils of buying a second-hand K without a FBMWSH
