Did the oil change on my car today actually. I've got a pair of these that only ever get worn when changing oil.

Oil resistant and keep most of the heat from your hands.


You'll want to drain the oil when it's hot... (within a few minutes of a 20-30 minute ride) it's runnier then and also all the "bad stuff" thats caught up in the oil won't have time to separate, so it'll come out with the oil rather than get left behind.

Sump and nut will get rather hot so normal latex gloves or bare skin is not wise.


I'd suggest you go for a leisurely ride for about half an hour, then let the bike idle for a few minutes while you get everything to hand, like drain pan, new filter, paper towels etc.


Oh and state the obvious time... don't start the engine until you've filled up with fresh oil.
(I have done it before, accidentally. I left the oil draining from sump, then changed pollen/odour filter, spark plugs & leads, cleaned air filter, then decided to finish off with the front of the car, so fitted the new oil filter and backed the car off the ramps. Realised as I was halfway down the ramps. Fook it another 2 seconds isn't gonna hurt while I finish getting off the ramp. Fresh oil, 12,000 miles later, no apparent damage done.)

just seen the bit in small text not done that myself yet but touch wood n all that. got to do my van next then the mrs car, she had only had the car a month (pug206) i told her dad i wanted a service he say no it dont but i went ahead and did it pulled the oil filter housing off to find the filter had disinterested, so much for not needing a service 3 weeks later a bit of the old filter got caught up in the oil pressure sensor
(he is a tight arse his car has not been serviced for 6 years )

when i did the service it was on 98k and a boy racer had had it tinted windows led rear lights it dont look to bad but im betting he had never done a full service on it all that needs doing now is the cambelt but im not to confident doing that never done one but i suppose you have got to learn one way then i can do it on my van if all goes well

To be honest the consensus seems to be it entire massively screws up your engine, or offers no noticeable gains. I wouldn't bother.

The idea of using a flush is to shift sludge. Unless your engine happens to be an ancient, iron-block car engine that has missed several services and only been run on the cheapest 20W50 mineral oil, you don't have any sludge.

Look at it like this - anything that's suspended in the oil will come out with the oil. Anything that's not suspended in the oil is harmlessly resting in the bottom of the sump. Why would you want to deliberately loosen any of that crap then pump it round all your shell bearings?

I know of a guy who sold a 350z to my mate, who showed a receipt to him, proud that he had the oil changed 5 years ago .... What is wrong with people?

:D see cmsnl for the exploded views.....

note clutch basket seem to act as centrifugal crap traps on bikes, difficult to clean the crap from them unless clutch baskert removed........

also lots of noooks and crannies, oil troughs etc etc etc which trap crap also, so oil goes black relatively quickly.....

if "sump floor" is get at able, the crap lying there could be flushed out with low pressure spray and solvent........like a car w/washer type spray and solvent.....

high pressure will tend to splatter the crap all inside the engine.........!!!

regular oil and filter changes and invest in a magnetic sump plug, money well spent! :karma:
