i use mobil1 20w50 vtwin but i would not be affraid of castrol 20w50 syn vtwin oil we have run castrol straight 30 in our farm tractors for 40 years (gas burners) with no oil issues what so ever. heck only one of our tractors has had the engine rebuilt and it had a ton of hours on it before we got it. now our diesel tractors we run mobil delvac 15w-40 still no issues......as stated before pick u out a full syn oil (NOT SYN3)!!!!!!!!!! And go with it your engine will be just fine
