yes it's getting cold here in texas, & fixing to change to a thinner lube but i bought some revtech 25/60 premium oil at a very cheap price; $1.25 qt.,an could not find any info on this weight of oil. it was about 110 degrees road temp this summer & i thought this oil might work out better this next summer than the HD oil i use now. any comments are welcome--2008 FLHTCU ULTRA still stock till we payoff this little darlin

 

I USED AND NOT BAD HERE IN SPAIN the time is very hot all year,and the bike is going very well with this oil.

 

I have no experience with that brand of oil but would think it wouldn't be a problem when outside temps are high. But I would not use it during "cool" or "cold" weather.
