    Main thing is to replace the hundred year old soup shite you have in there with fresh stuff
    That would depend on whether or not the halfrauds stuff was the right grade for the forks wouldn't it? and if you think there is no difference between fork oils, why replace the old soup in the forks? that is even cheaper than the Halfrauds stuff as you already own it.

    Have you ever set off on a ride in the winter and felt that the bike feels a bit crap, a bit wooden, but as the ride goes on it gets better, that is probably the suspension oil getting up to temp and it's viscosity coming into the range the damping is set for. I have felt this and the best oils (not necessarily the most expensive) with a high VI minimise this effect.

    The bottom line here is, the Halfords fork oil is 8 and the Silkolene Pro RSF fork oil is 11. Is anyone in this day and age that hard up they cannot afford an extra 3 for a known quality over the shite Halfrauds sell?

    The Halfords oil is made to make Halfords the most profit which is why they change their suppliers every now and again, their suppliers cut corners when they make the oil they sell Halfords because they need to make a profit to stay in business.

    Silkolene make oil and their business is dependant on the quality of said oils.

    If you want consistency in performance - go with one of those two.
    Which Motul and Motorex oils do you recommend?, one of the Motul oils in the chart i have linked to is the worst oil on there.

    Re: Factory fork oil.

    I bet that most (if not all) are derivatives of ATF and just labelled differently. After all what is fork oil ??? It's only a Hydraulic fluid and nothing else !

    The so called performance of the oil can be easily influenced by the air gap in the top of the fork tube. This gap is averaged out by most bike manufacturers by simply stating the amount of oil required per each applicable Workshop Manual. But this is easily changeable depending on your own personal requirements (in addition of course, to the adjustable damping possibilities).

    You're just being ridiculous now on purpose
    Of course you buy the correct grade (they do 5W and 10W).
    Of course you change the soup to fresh stuff.....just saying new stuff is probably very similar in performance and may come from the same source.

    Amazingly I actually agree with BruceJ on something.
    Fresh oil and getting the air gap right is the main thing.

    You go ahead and waste your money, at least it's stimulating the economy

    Thanks Purge.....appreciated.
    Now here is something I have just remembered re oil (be it fork or whatever), some years ago I was informed by a Rolls Royce engineer that oils DO NOT break down, with age/constant use they get contaminated/dirty and this of course can influence their performance. All oils can be cleaned with the right equipment and this is common now-a-days. There are specialist companies that do this. Rolls Royce do recommended the use of re-refined oil. Very often re-refined oil is better than the 'new' stuff because often, in the process, additives are removed too. Additives as mentioned in most oil specs are what really ?
    Also, I mentioned 'new', above......because I doubt if anyone can be sure that the oil they are buying is new or if it is re-refined. I apply this thinking to all brands. When it comes to marketing oil, it is a simple statement of 'bullshit baffles brains' !!!!

    who's to say what you say is correct, only you , as everyone else has their own beliefs, and even being in the motor trade eventually things will change from what you learned in college, such is the way of life

    ATF is not fork oil but has been used and even recommend by h*nda for one of the Moldwings I believe. But it isn't suitable for all forks and will probably be too thick in the later cartridge forks. If the grade is suitable for a fork though, it does have a very low pour point so would be good in cold countries.

    The air gap will not affect damping but it will affect the rate of the spring when compressed, this is one of the reasons why I don't like progressive springs as there is already one in your forks ie the air gap is a progressive spring.

    Half right, the base stock doesn't degrade but the additives do. Companies like Comma (I think) used to collect old oil and remove the additives, clean the base stock and then add their own additive packs and resell the oil.

    Oil would be no good without the additives.

    Synthetic oils are not remanufactured.

    Oh, go on, it runs though the internet not just this thread. Which Motul and Motorex oils do you recommend?
