I am looking for 10w40 and found a Auto Parts store has Valvoline 4-Stroke ATV 10w40 Motor Oil, can I use it for my Kawasaki Vulcan 800 wet clutch? Is it any good?
What I won’t use from my personal experience with a wet clutch shared sump are auto specific oils or synthetic oils even motorcycle labeled bottles. After less than a thousand miles the slippage was just so apparent.
This was back in the late 80s early 90s with a ‘86 Ninja 600r. Purchased used with a history of rider abuse. Replaced with a new Barnett clutch pack and changed oil with 20w50 Pennzoil conventional. Rode for weeks and the rpms started to mismatch relative to clutch lever disengagement so drained motor oil and replaced with motorcycle specific Spectro and got noticeably better. Never changed the clutch pack ever again.Your clutch slip after a thousand miles??? but want was the total mileage on the clutch???
Valvoline ATV oil has slightly lower Z and P (1020/930 ppm) vs their Motorcycle oil (1120/1030 ppm). I got some Valvoline ATV oil on super sale at AutoZone a number of years ago.I am looking for 10w40 and found a Auto Parts store has Valvoline 4-Stroke ATV 10w40 Motor Oil, can I use it for my Kawasaki Vulcan 800 wet clutch?
