1990 Yamaha SRX250 opinions

One bit of advice often repeated here....

Don't use car oil, don't use car oil, don't use car oil, don't use car oil !!!

It will bugger your clutch up due to containing what's called friction modifiers.

Do a search here in Kiwibiker, you'll find lots of threads containing what people consider is the best oil, but to cut a long story short, I run Shell Advance 4-stroke Motorcycle oil available at any (or most) Shell Garages.
Works well in the NZ and VT 250's.

Yeah, I have read a fair threads about the friction modifiers and how they affect the clutch. Thanks for the info about the oil.

Bullshit,bullshit,bullshit! ALL car engine oils DO NOT contain frictions modifiers,only some,and they will be marked as such.Motorcycle specific oils are higher in moly than car oils - moly is used as a ingrediant of friction modified oils,ester is also used as a friction modifier,the highest quality synthetics are esters.How about some facts before you use such a wide brush in your statements.

So what specific weight of oil should I use, I don't have a manual so would it pay to ask a Yamaha dealer??

Umm,...actually you're right, they are marked as such. I should know this after working in the petroleum industry for 15 odd years....
(but thanks for the lovely way of telling me I was wrong, Motu......)


But as a general rule, use motorcycle oil , as just about everyone I know that has used car oil has had clutch trouble (and we're talking about wet-clutches of course). That I can vouch for !!!!

I use a 10w40 semi-synthetic in the NZ250. I get good results with that.
Once again, it is only my opinion.

I use delo 400 15-40 diesel engine oil in the XT and the YZF before that. Works a treat. Oh and I change it every 6000kms.

OK, so I went to a couple of bike shops and ended up getting a 4 litre of Spectro 4, plus an Oil filter and a new Spark plug. I was just wondering if it is necesary to fill to oil filter before installing it or if I just chuck it in and it will fill up when I add the new oil??

[Motu]

The oil filter cover has a bleed screw,loosen it off and run the engine,when oil flows out lock it up - don't do this in your lounge,it's messy.
