If it is energy conserving, then it is NOT good for the Rincon. I use Rotella synthetic in 5w-40 which is good. It was developed for diesels and works well in gas engines, including ATV's. It is better than car oils for ATV's and motorcycles since the oil is changed frequently. It actually protects better than car oil. I had quite an extensive conversation with a lubrication engineer about this oil. It is about $12.00 agallon at Walmart.
Thanks John, This oil is sold just for atv's wet clutch. It doesnt say energy conserving. Was wondering if any guys use it in these temperature ranges 20-50. I would like a better oil for our tranny isues along w/ a better price. The manual says 10w 40 was recommended for 0 - 100 degress, or something like that.. It seems that nobody in this forum uses this weight oil????
There was a noticeable difference in the transmission when I changed over to Rotella. Suddenly the transmission shifted so smoothly that when in Auto mode it is hard to tell when it does shift and can barely feel it even when I do the shifting.
