none believer in synthetic

picking up new fe 570 next weekend , if the oil is changed every 400 to 500 kms do you need to use synthetic oil

well just use what the factory recommends. they aint gonna say use synthetic for no reason are they? or just put any old ***** in and wonder why your engine is f+@ked. but i suppose the choice is yours

I use synthetic oil and have since day one. If anything ever happens to the engine at least I will know that it had nothing to do with the oil I'm using... peace of mind really... I would asume for your warranty you will have to use what the factory recommends, at least untill the warranty expires.
It would be better to go off the hour meter instead of the odometer for oil change intervals.
Like weapon272 says... the choice is yours.

Probably not.
I would let the type of use and conditions determine what I was going to use.

I just bought a FE390 and asked the samme question at the shop. They said I MUST use the oil as per the manual which is synthetic. It cost me $AU119 for 4 litres! Warranty here is only for 30 days.... just use what they recommend. You bought an expensive bike - dont cheap out on the oil that feeds it.

I like mineral oil for numerous reasons which I will not enter into debate on this forum.

When I first bought my 570 I dropped the factory oil before even starting the motor. I replaced it with mineral oil and have had mineral oil in ever since. (only just under 1,000 kms so far)
I will use mineral oil for the life of the bike. But the funny thing is when I returned to the dealer I got dragged into conversation with him about something else, and then the subject turned to oil. I never told him about using mineral oil as I did not want to jepardize any possible warranty claims due to NOT using the recommended product. He was talking away and mentioned that their dealership changes all the oil in ALL their bikes from the factory supplied oil to mineral oil before they leave the shop !
I was glad to hear this as it's the first dealer I have dealt with that has strong enough views on the topic to go to the time and expense to change the oil in the bikes he sells !

The bike needs to break in and the motor will take forever to do this on synthetic oil, it;s as simple as that.

Another oil thread eh ? My $.02, the tractor oil has done all right in my bike, I have 3300 km on her now.

U talking bout Delo 400 ?

yeah bro the Delo. Trying to be sly and not actually say the name coz I know how tichy people get about this subject. Funk it my hats in the ring now, in for a penny in for a pound, Motul 5100 is rubbish as are most synthetic oils, big lot of **** all for **** all I think. I built a motor for a friend ( yami Rhino ) he ran it first up on synthetic and ****** it, heaps of blow by, the rings never had a chance to bed in. Synthetic is way too expensive for me and if ya change the **** every 3 friggen hours whats the difference ? So come on people lets see some passion here, hopefully I've stirred it up enough now. :twisted:

I am using the Delo 400 as well now. Only started using it on this bike and so far I am wrapt, and your right, frequent oil changes it's a waste of time using synthetic IMO

I also ran my bike in by this method which also stirs up a hornets nest at times.

oh yeah its right up there with religion and politics. This is the second bike I've run delo in and at $6.50 a litre it is good value too.

synthetics and semi synthetics make the clutches go to shyeeete too quick for my liking

seems that at some point the better the oil is for the bearings piston and stuff the worse it is for the clutch

as i was once a dealer i was pushed towards using the oil recommended by the factory for warranty reasons and thats what i had to tell the customer, Motorex was the oil they chose for the bikes so thats what i had in my workshop. But back in 2000 it was Shell, tommorow it may be Motul, Mobil, Belray, Castrol it depends who give them the best deal to supply oils in all the bikes that leave the production line. Motorex and KTM are in bed now
Ive used Motorex 10/60 Crosspower in my Berg 650 07 because i stole it from myself for free as i had it in bulk in my workshop its done 10 000 km and i still have not rebuilt it except for replacing the crap mainbearings after 1000k.
Ive seen inside a lot of engines and mine needs ringsand will be getting a piston kit soon as they can crack after a lot of ks so thats when i will look at the wear inside.
I dont believe in changing the oil every ride its a waste of money, no complaints about the oil heater in my workshop it ran real good on full syn from the waste oil.
I always seem to run my oils longer as a mechanics bike is always the last serviced so i got value from full syn but if you cant help yourself and feel the need to change it every ride run Delo or a mineral oil.
I never did follow up what grade of Motorex oil they put in the bikes new but i dont think it was the full syn maybe Formula 4t, i will find out as i agree with running the bike in on mineral to bed in the rings properly.
In saying that i replaced the rings in a KXF 250 recently and use the cheap Shell SX4 and it blew thick smoke as soon as it started, i replaced the oil with Motorex full syn and it stopped so im back on the fence again.
You will always get a debate on oil and im still sitting on the fence with this one im just having my 2 bobs worth.

I have been using Motorex power synt 4t 10w 50 from the start for years.
I work at a heavy equipment co. and we do stock the "Delo 400 hd 15w 40 mg"
We have it in the hundreds of gallons and it would be free for me to use.
I just like the motorex and money is not the issue.
I change every 2 rides or 5hrs.

pollo

I did some tests a while back with the lathe, started an agressive cut with power feed through the half nut then tip oil on and see what happens

some of the full synth oils are so slippery they will stop the cut and push the tool out of the way till it all gets so hot the oil evaporates.

delo400 will not stop the cut

so you'd have to say the synth ones are better for the mains and piston etc

different story with old oil; old delo400 (10 hrs) is better than old full synth I can feel the clutch action change at about 5hrs with the delo and 3 hrs with motul300v. so I change the delo at 4 hrs. i think the clutch slips more with the motul so it stresses out the oil more even though its "better oil" it gets a harder time in the clutch because its too slippery

If i didn't have to use the clutch much maybe desert racing etc id be happier using full synth but the way I ride I get better feel and better useful life out of the clutch with delo400 and 10% moreys.

Hey Bushie you always go to the extremes when we need an explanation or a scientific answer, have you ever considered applying for a job on Myth Busters.
Keep up the good work.
John ORANGEBERG

myth busters would be fun for sure heaps of things I'd like to blow up

I can feel the clutch action change at about 5hrs with the delo and 3 hrs with motul300v. so I change the delo at 4 hrs. i think the clutch slips more with the motul so that slipping stresses out the oil more so even though its "better oil" it gets a harder time in the clutch because its too slippery and then the oil and the clutch can get fried. if you're not using the clutch though its gotta be better for the teeny mains to have the slippery oil.

ive read somewhere maybe quads forums that some guys reckon the only way to have the clutch last in high load high grip situations is to use a modified suter slipper so the more tourque that goes through it the harder the plates get pressed together.

two shafts one out of the blown up and burnt 550 at 170hrs it had a diet of motul 300V 10 hr changes that shaft is not stuffed but its definatley not new.

the one on the left is mine at 220hrs you can still see the machining marks from the factory. delo400 and 10% moreys changed every 4 hrs.

doesn't prove much other than delo is looking good enough and even motul 300V can't save a 550 engine with a twisted crank and no endfloat.

the pic is truncated in the page but if you click the link below it works fine

hey bushie what is 10% moreys

moreys heavy duty oil stabiliser its great stuff

be careful though if you have a silver plated big end cage. the moreys eats silver
