4stroke oil

[barty5]

Heres a link to some info on this rotella stuff, the yanks on thumpertalk swear by it, I wonder what the equivalent oil is here? Delo?

you gota remember yanks are lazy so any oil that says it can be used for multiple uses no matter what it is will sound good to them. they would brush their teeth with it if you put it on the label and it tastes good.

niether of these previous 2 responses are relevant to my question, firstly should clarify that hondas and probably some ther bikes run seperate engine oil to trans oil. so clutch issues are un related. a clutch is neither a 2 or 4 stroke object.

Clutches are one of the very biggest destroyers of oil especially if the rider is inclined to fan the clutch all the time. If that is happening and duty is shared with the engine then wear accelerates rapidly.

If you hadn't guessed I've nearly run out of filters and oil so will need some soon. I call you later.

My response was to the thread topic/starter Rupecopp i.e. use the best oil you can, whatever type/part of the engine it's in, cheapest insurance if you are keeping your bike a while, if not, use cheap stuff and sell it to a stranger before it costs a lot more than few litres of oil. There's usually a good reason why and oil is cheap.

Yes, many dealers have come unstuck because of less than honest owners at trade in time. THAT SUCKS BIG TIME.

sweet ive got one filter can get more

Oils cheap, just use a big well known brand I always like Castrol myself because they don't have service stations, and they used to make Castrol R.

If your bike is indeed a KX250F it holds about 1 to1.5 litres of oil and that oil is highly stressed. I would absolutely not be preoccupied about price, Id be much more concerned about the best quality oil and changing it often. Especially given that its specific horespower ( sae rear wheel ) is around 140-150 bhp per litre and cooling is marginal.
So often subsequent owners ( and dealers ) foot premature repair bills because the previous owners have taken short cuts on maintenance.

What is your preference with regards Synthetic vs non-synthetic, the reason I ask is the latest Castrol Power GPS is rated API SJ & JASO MA2, but is semi synth, it's what I've been using ( 5 hour oil / 10 hour oil + filter ).
But I see there is a guy on tardme doing 20 litres of Elf MOTO 4 HP ECO Semi-Synth for $176.50+freight, mind you it's API SH & JASO MA2.

Put it this way I'll go through around 32l in the next 12 months, at $90 a 4l ( fully synth ) that it is $720 vs $320 ( semi synth Elf ), maybe I'm poor, but $400 is a chunk of change if I can save it, assuming I'm not risking my clutch & bike in the process.

P.S. at 1.5 litres of oil a kx250f would be more like 30bhp per litre, they tap out under 40bhp, to be safe say 50bhp per litre, but still that is way short of 150.

i use the elf moto4 ill check what $$ it is normally for you in the morning might even be able to do a better deal i run the stuff the same around 5 hours but do filter at the same time as i get them so dam cheap.

i suspect he ment per litre of capacity say 35hp x4 =140hp

shit its a lot of oil changes glad I've got a 2t

2strokes need the trans oil done just as often

Thats the stuff you've been givin me isn't it??? The stuff is fully synth and going good.

Been running an Elf synth oil, changing every 5hrs and filter every 10hrs. No problem with it just doing a bit of digging really, as mentioned elsewhere in this thread I keep seeing the yanks banging on about this rotella stuff. Though I might of been in the dark so asked on here, but from the rsponses I'll stick to what I've been using. althou don't know how much differance semi synth and synth make.
Cheers

yes it is the synthtics with stand heat better plus whole heap a other shit

Elf moto 4t, buy it in bulk from Mr Motorcycles, not sure about cost but what ever it is it's cheap insurance against the price of a rebuild.

yeah i realise clutch fucks oil real fast, but that post was in reference to the previous post saying about friction modificators etc vs clutch plates. this is not an issue for honda "4 stroke oil" which i interpret as 4 stroke engine oil.


and thinking about this topic, it does work out cheaper to run a 2 stroke. i use 750ml's of oil to 30 litres of fuel. for "engine oil" - we will leave a trans out of the equation as it makes no difference if its 2 stroke or 4
for a 4 stoke to use 30 litres of fuel i'd suggest will be running about 7 hours. which sounds like longer than how often you should be changing the 4 stroke engine oil. therefore using about 750mls of oil to every 30 litres of fuel

and then theres the filters on top. plus the actual effort of warming, draining, extra wear of alloy threads, replacing filter, discarding old filter - (see emmissions and all that shit) re-filling / spilling

lol theres a good arguement for the 2 stroke lol
