Stihl 4 mix oil equivalent

[Rye Oil Ltd]

Hi all we have a few customers who use The STIHL Ultra HP 4 mix oil.

We already make an oil that is a direct replacement for the semi synthetic 2-stroke that all the major makes sell, but I cannot get anymore info on this particular oil.

Are the any other oils that are used in the same bits of kit that I may be able to find spec sheets for?

No one got any info on this? What sort of machinery is it used for etc?

The Ultra oil seems to have been developed to combat some of the troubles that have plagued the Stihl 4-mix engines. It seems that deposits were building on the valves and guides as well as the combustion chamber causing failure.

 

I believe that HP Ultra is a very low deposit, hence clean burn oil.

 

What I find strange is that we all go on about using oils of JASO-FC or FD rating, yet HP Ultra is only an FB rating.

 

I am sending you an email.

Thanks Barrie I appreciate the info.

Problem is he is worried about warranty issues so uses the Stihl spec oil, but if I can find an oil that matches the spec then his warranty stands.
