Oil Change

The obvious first question/s would be how many miles has the bike covered and how long prior to being laid up was it since the oil and filter were last changed? If the answer is very few miles and less than a year, I think I'd just run the bike myself. Its your call of course and if you do it yourself an oil + filter change isn't very expensive.

 

I would go on how old the oil is and and how many miles it's covered. I changed the oil and filter in March last year on the ZZR and covered just over 1k miles since. It's not moved since before Christmas so I've just changed the oil again this time. TBH the oil came out very clean so I could probably have left it in but that's just me being a bit OCD.

 

I'd leave it tbh if it's not done a lot of miles beforehand.
Like others have said, it's not expensive to do if you want peace of mind!!

 

I’ve just done an oil change after 7000 miles and just over 14 months. Think it was ready fo4 it.

 

oil is cheap.

when ever you are in doubt, change it and don't worry.

you have nothing to lose by changing it, and frankly, nothing to gain by delaying the service.

 

Personal thing but I would check level if it’s fine and oil is clean leave it,my triple had done about 1k in last year after I broke my wrist but just mot today,going to change oil and filter in summer already got triumph filter and got Halfords trade cares for the castrol oil ✅

 

Mileage is the key when it comes to oil and how the engine handles things of course, but most modern oils are fine just sat in an engine.

 

Laying vehicles up, particularly older ones, for long periods will be come more of an issue in future, not because of oil longevity but down to the increasing use of Ethanol in fuel.

 

Had been lying about 6 months on sorn so prob ok it’s 2011 speedy

 

True there has been talk of ethanol affecting the friction modifiers and oil film thickness, but I would suspect that counter measures are already under development and testing since the talk of the amount of ethanol is being increased.
But with today's lean-burn engine designs and better ring seal the amounts of fuel and combustion gases that actually get past the rings and guides is pretty minimal compared to engines of 20 years ago......we hope.

 

I was thinking specifically of fuel system related problems. Ethanol is hydroscopic, more so than "normal" unleaded with all the problems that entails plus it can affect seals and plastic parts.

 

I wouldn't change it I do the oil every 7000km .oil will Easley last a year if you dont do the miles it starts lose it verlosety after year so I am told so that's what I will stick with
