Can't find any Mobil 1 75/90 locally,found some on-line but there's a minimum order of 5 litres at around $120...the local car mart has it's own brand 75/90 semi synthetic at around $5 a litre but don't know any bikers who have used it, so no feed back on that.....should I just order some Formula + from the nearest Harley shop?......cheers.

 

Have you tried calling Mobil UK for retail location info.?

Any reputable brand 75w90 synthetic Gear Oil should also be fine.

 

Thanks cHarley...I'll call them Monday......I did Google Mobil and didn't come across that......Isn't Formula + rated then?

 

Formula+ is OK, and definitely better than running Syn3 in there. But, I would still prefer a top quality Synthetic over the Formula+, I find it shifts better and quieter.

 

When going through the past posts on the subject....someone posted about not putting 75/90 in pre 04 Sportsters......any thoughts?...mines 2000.

 

I was told to use 20w50 not 75/90 in Sportsters before 2004. I had asked about this the other Day. Look back in the previous posts it should be in here. I am getting a 2001 Sportster 1200.

 

My owner manual says to use H-D Sport-Trans fluid....all I can find out about this oil is that It Is semi synthetic,can't find an SAE number for It.
Is there a difference in the clutches pre and post 04's?

 

I saw 1 guy post to that effect, but it makes no sense to me. Back before Formula+, Harley recommended Sport-Trans Fluid in the Primary/Tranny on Sportsters and it was an 80w Gear Oil. Go with the Gear Oil is my recommendation.

 

Will do cHarley....your advice Is good enough for me.
