Where did all my oil go!?
Hi all,
Started up the bike to leave work yesterday and thought the engine didn't sound quite right, so switched it off and started having a look around the engine (thought it was something touching something), nothing wrong there, so checked the oil, and theres was nothing in the window :shock: had to tip the bike right over before the tiniest bit of oil appeared in the window... now, I know your supposed to check the oil level regularly but since its only approaching 4000miles thought it would be ok, as it was changed at the 1st service. Sheepishly drove to the nearest garage i could find that was still open (pole position on new kent road) and filled her up...took a litre! which filled it just below the "full" line. I asked the mechanic in there if he knew where it had gone as it was definately not leaking anywhere, his exact words "dunno, its just a sh*t engine" :? I'm taking it in for its 2nd service next friday so will ask there (without saying how low it was to avoid hearing my warrenty being ripped up out the back) But just wondered if anyone on here had experience this or knows what could have caused this... i may just be being a numpty and its normal but i dont think so... Its a K6 btw bought from new :smt117 --- sorry just love that icon lol |
The oil fairies steal it in the night. The dirty little bastids...

I have the same problem, my all the engines I've had in the SV have drank oil. I know I'm not dropping any as I park in the same place I just have to remember to fill it up regularaly.
The problem is the SV only has a pressure gauge and not a level warning so be careful! |
What a lot of helpful answers :)
It's going out the bottom, past the pistons or valves, or out the top. Or possibly was never there in the first place. You relally need to know how fast it's dropping... |

Check your oil at least every week, Big Ape made the very good point that if you check it when you've filled up the garage forecourt is usually flat, and they sell oil if it's low! Some engines just burn a little oil, it's not a problem, or the most expensive thing in the world. I would probably say that if 1L took it up to "Full" then it *probably* wasn't low enough to do any major damage unless you were beating it to within an inch of it's life. Well done on checking when you did! Jambo |
I would've thought less than a litre (maybe 7--800 mls if your litre took it to the full line) over 3500 miles would be quite reasonable.
Personally i'd make sure it wasn't dropping rapidly by checkups after every ride, and if not i'd accept it from a twin. Did you run it in very gently? That can cause high oil consumption. |
my expereince is that if you keep the level in the sight glass, rate of consumption is not bad, if you let it go below the sight glass, the rate will increase
the first 40k or so, I never had to add oil but once or twice, once I had 50k on ly SV, I use more oil, but the rate was sporatic, long high speed highway stints consuming the most. this continued till 120k or so when my consumption rate became more consistent, at 130k, consumption was regular, prolly 250ml every task of gas, the only time it smoked was on startup and redline accelerations and decellerations from redline at 135k, I had compression test done.... 210psi rear, 90psi front :cry: teardown indicated EVERY valve guide worn well beyond service limits, one exaust valve in the front wasn't seating properly pistons & rings were worn but not beyond service limits, cam chains were worn beyond limits no significant wear other than that, bottom end was tight |
