Oil

I use castrol GPS in mine but have to say, everytime I go into Halfords they haven't got any on the shelf, the one time they did they only had it in 1ltr bottles so I ended up paying slightly more than buying a 4 litre bottle of it.

Really annoying.

"Motorcycle oils and passenger car oils are very similar, with the exception of a couple of areas that are key to motorcycle operation. The first area concerns common sumps, or the use of motor oil, to lubricate and cool the transmission. As you know, in a passenger car the transmission is lubricated by an ATF fluid, which has frictional properties required for transmission operation. In a motorcycle, where the transmission may be lubricated by the engine oil, an engine oil that does not have the same level of friction modification (for fuel economy) of a typical passenger car engine oil will provide better transmission performance in terms of transmission lock-up and slippage. So motorcycle engine oil does not contain the friction modifiers of a passenger car engine oil. The second area of concern for motorcycle engine oils is that they tend to shear (breakdown viscosity) more quickly than a typical passenger car."

The GPS motorcycle specific oil is the right oil for a Bike as normal car oil doesn't do a 'WET CLUTCH' any favours,thats proberbly why so many people complain of clutch drag !! its not worth saving a few quid to risk damaging your motor!

yes i was wanting to do the a oil change at the weekend but i dont know which oil to put in it can the 2001 sv650 take fully synthetic or semi and is 10w 40 the best grade to stick with

Dont do it car oil in bikes just isnt good bike oils have many different additives to allow it to survive in a harsh enviroment car oils just wont stand upto the bike gearbox and will do your wet clutch no favours. For anyone thinking about scimping on oil think about this.

If you had a super model girlfriend would you feed her chips??

Specifically that's referring to cars with auto 'boxes, (ATF = automatic tramsmission fluid), was it a Yank site? a large percentage of their cars are auto. Over here our cars being mostly manual they use an EP oil in the 'box.

Anyway it may well be valid advice all the same, modern oils are very good but all the same I'd still use a bike specific semi-synth.

For a while yes, I probably would - most of them are too skinny.

If this were SV Rider everyone would be telling you to use diesel oil.

I went back into the one in Newbury because I was passing, and they'd got some more stock in, incl GTS, so I bought some of that. I'm sure the Halfords own brand would have been fine, but for an extra £6, I tought I'd go for it. 5L will last me a long time, so I don't feel too riped off. Of course, it could be that exactly the same product is in the Halfords containers...

Thanks for the advice

Anyone got any idea why the oil is red? Just curious.

Someone told me once that Castrol colour their oils according to grade and viscosity. This might be rubbish though.
