In the cooler months I run 5000 miles and change just the filter and top off with oil using synthetic. I do full oil and filter during the hot months of the summer though but still at 5000 miles.

 

I've had prompt answers from them on the few occasions I've emailed them, before buying my motor and with the odd query since. Fortunately I haven't had to test them with anything more than simple questions!

 

All this is good to know, holy crap new cars run 7500 or more between changes, a once in a blue moon extended oil change wouldn't cause any long term damage in my view. After all, if the motor is broke in, there shouldn't be a lot of garbage floating around in there. mho., if regular changes were made, in your case, i'm positve they were.

 

Have a S&S 113" in a FXR......using a Purolater ML16822 filter, and Amsoil 20W-50. It gets changed @ 4000 miles......

Run the same filter/oil in my 80" FXRS.......

Enjoy your upcoming trip .... sounds like an adventure!

 

Many of the oils and filters you chaps have easy access to in North America don't make it across the pond, or are very expensive, like Mobil 1 oil which is only available (in my experience) from our few S&S dealers. We don't have them on every street corner!

For reference and British readers, I have uncovered a very suitable looking oil by Silkolene (British old chap!). They produce a mineral 20w-50 oil for Harleys and V-twins, also a synthetic 10w-50, which is the one I will go with. They can be had discounted from Opie Oils.

So I reckon I have this cracked now!

 

When I lived in the UK you could get Mobil 1 from Halfords and any Mobil gas Station.

 

I have already looked into this at some length. It is true that some Mobil 1 oils are available in those outlets, but only a limited choice and none of the motorcycle range, including V-twin. What is available here is darned expensive, roughly twice as much as the Silkolene I mentioned. It's a bit annoying, as Mobil is/was a French company and they don't serve Europe as well as they do North America! You can compare different markets by checking their website.

 

Aha, I didn't know Mobil made V Twin oils....but hey! We race in the NZ Classic series with Silkolene, its very good!

Anyway, why would you wanna put money in French pockets when you can "Back Britain" (that just revealed how old I am) ;-)

 

Good to hear Silkolene is making it down under old chap. As for using Mobil 1 V-twin oil, it is S&S's recommended lubricant and while my motor was under warranty (3 years - don't get that with a Harley!) I obediently stuck to using it. I've been meaning to find an alternative and this long trip has got me looking into the subject at last.
