Engine flush with car oil?

[Guest]

Evening chaps/chappettes...

I'm going to do my second oil change since having my new bandit and was thinking about flushing the engine before adding new fresh oil...

...my plan is to drain the oil and fill it up with some car engine oil I have, run it for 10 mins or so to flush it a bit, drain that and then add my motorcycle oil.

The car oil is the same viscosity (10w40) and is semi synthetic, but its very likely to have that compound in it to reduce friction and wear which of course is why you shouldnt use it in a bike.

But this is my question... for the purposes of flushing the engine, and then adding proper motorcycle oil do you think it'll be ok? My feeling is that it will be just fine... after all I hear of some people who all they use is car engine oil... is the relatively small amount that would be left over likely to cause a problem when mixed with 3+ litres of motorcycle oil?

Thanks in advance!

PS

I have so much car engine oil its unreal... maybe 40L... so I dont mind "wasting" it!

Don't know if it's worth it rick, pull the plug & drop the oil while it's hot,let the bike stand till it stops dripping,

if your on the centre stand sit on the rear seat & get the front wheel of the deck, there might be a pocket of oil left at the fwd end of crankcase,

If your changing the fillter can't see the need to flush,, but that's just my opinion, no doubt someone will say different,,

In practice, I agree with RT, and doubt i'd ever bother with a flush. But you can get special products for flushing, you sling it in, run it up for a few minutes to let it circulate, then drain it off and fill up.

aarghh.... NO

don't use them, i did once.... and i blew my engine within 5 minutes

the addatives thin the oil so it runs down through the drain channels easier. trouble, this happens pretty quickly and it you give the bike too much revs, you run the serious risk of engine seizure. i managed to blow a honda maggot (usually unburstable engines!). seized a piston, snapped a con rod and punctured the engine casing. the white oil smoke plume could be seen for miles

just warm the engine and drain as normal. if you change the filter at the same time you'll of replaced ~98% of the oil anyway. when manufacturers recomend oil change intervals, this is taken into account so as long as you stick with regular oil changes and do it properly with a new filter each time, there is no need to do anything else.

if its your second oil change there would be no need to flush it

in fact i wouldnt even bother flushing any engine!!!

again these additives do more harm then good stay well away from them

just do the oil and filter as mentioned above
